Quantitative ultrasound (QUS) is a promising tool to estimate bone structure characteristics and predict fragile fracture. The aim of this pilot cross-sectional study was to evaluate the performance of a multi-channel residual network (MResNet) based on ultrasonic radiofrequency (RF) signal to discriminate fragile fractures retrospectively in postmenopausal women. Methods. RF signal and speed of sound (SOS) were obtained using an axial transmission QUS at one‐third distal radius for 246 postmenopausal women. Based on the involved RF signal, we conducted a MResNet, which combines multi-channel training with original ResNet, to classify the high risk of fragility fractures patients from all subjects. The bone mineral density (BMD) at lumber, hip and femoral neck acquired with DXA was recorded on the same day. The fracture history of all subjects in adulthood were collected. To assess the ability of the different methods in the discrimination of fragile fracture, the odds ratios (OR) calculated using binomial logistic regression analysis and the area under the receiver operator characteristic curves (AUC) were analyzed. Results. Among the 246 postmenopausal women, 170 belonged to the non-fracture group, 50 to the vertebral group, and 26 to the non-vertebral fracture group. MResNet was discriminant for all fragile fractures (OR = 2.64; AUC = 0.74), for Vertebral fracture (OR = 3.02; AUC = 0.77), for non-vertebral fracture (OR = 2.01; AUC = 0.69). MResNet showed comparable performance to that of BMD of hip and lumbar with all types of fractures, and significantly better performance than SOS all types of fractures. Conclusions. the MResNet model based on the ultrasonic RF signal can significantly improve the ability of QUS device to recognize previous fragile fractures. Moreover, the performance of the proposed model modified by age, weight, and height is further optimized. These results open perspectives to evaluate the risk of fragile fracture applying a deep learning model to analyze ultrasonic RF signal

Osteoporosis is common and the health and financial cost of fragility fractures is considerable. The burden of cardiovascular disease has been reduced dramatically by identifying and targeting those most at risk. A similar approach is potentially possible in the context of fragility fractures. The World Health Organization created and endorsed the use of FRAX, a fracture risk assessment tool, which uses selected risk factors to calculate a quantitative, patient-specific, ten-year risk of sustaining a fragility fracture. Treatment can thus be based on this as well as on measured bone mineral density. It may also be used to determine at-risk individuals, who should undergo bone densitometry. FRAX has been incorporated into the national osteoporosis guidelines of countries in the Americas, Europe, the Far East and Australasia. The United Kingdom National Institute for Health and Clinical Excellence also advocates its use in their guidance on the assessment of the risk of fragility fracture, and it may become an important tool to combat the health challenges posed by fragility fractures

Hypovitaminosis D has been identified as a common risk factor for fragility fractures and poor fracture healing. Epidemiological data on vitamin D deficiency have been gathered in various populations, but the association between vertebral fragility fractures and hypovitaminosis D, especially in males, remains unclear. The purpose of this study was to evaluate serum levels of 25-hydroxyvitamin D (25-OH D) in patients presenting with vertebral fragility fractures and to determine whether patients with a vertebral fracture were at greater risk of hypovitaminosis D than a control population. Furthermore, we studied the seasonal variations in the serum vitamin D levels of tested patients in order to clarify the relationship between other known risk factors for osteoporosis and vitamin D levels. We measured the serum 25-OH D levels of 246 patients admitted with vertebral fractures (105 men, 141 female, mean age 69 years, . sd. 8.5), and in 392 orthopaedic patients with back pain and no fractures (219 men, 173 female, mean age 63 years, . sd. 11) to evaluate the prevalence of vitamin D insufficiency. Statistical analysis found a significant difference in vitamin D levels between patients with vertebral fragility fracture and the control group (p = 0.036). In addition, there was a significant main effect of the tested variables: obesity (p < 0.001), nicotine abuse (p = 0.002) and diabetes mellitus (p < 0.001). No statistical difference was found between vitamin D levels and gender (p = 0.34). Vitamin D insufficiency was shown to be a risk factor for vertebral fragility fractures in both men and women.

Aims. This study aims to define the epidemiology of trauma presenting to a single centre providing all orthopaedic trauma care for a population of ∼ 900,000 over the first 40 days of the COVID-19 pandemic compared to that presenting over the same period one year earlier. The secondary aim was to compare this with population mobility data obtained from Google. Methods. A cross-sectional study of consecutive adult (> 13 years) patients with musculoskeletal trauma referred as either in-patients or out-patients over a 40-day period beginning on 5 March 2020, the date of the first reported UK COVID-19 death, was performed. This time period encompassed social distancing measures. This group was compared to a group of patients referred over the same calendar period in 2019 and to publicly available mobility data from Google. Results. Orthopaedic trauma referrals reduced by 42% (1,056 compared to 1,820) during the study period, and by 58% (405 compared to 967) following national lockdown. Outpatient referrals reduced by 44%, and inpatient referrals by 36%, and the number of surgeries performed by 36%. The regional incidence of traumatic injury fell from 5.07 (95% confidence interval (CI) 4.79 to 5.35) to 2.94 (95% CI 2.52 to 3.32) per 100,000 population per day. Significant reductions were seen in injuries related to sports and alcohol consumption. No admissions occurred relating to major trauma (Injury Severity Score > 16) or violence against the person. Changes in population mobility and trauma volume from baseline correlated significantly (Pearson’s correlation 0.749, 95% CI 0.58 to 0.85, p < 0.001). However, admissions related to fragility fractures remained unchanged compared to the 2019 baseline. Conclusion. The profound changes in social behaviour and mobility during the early stages of the COVID-19 pandemic have directly correlated with a significant decrease in orthopaedic trauma referrals, but fragility fractures remained unaffected and provision for these patients should be maintained.

Aims. Minimally invasive fixation of pelvic fragility fractures is recommended to reduce pain and allow early mobilization. The purpose of this study was to evaluate the outcome of two different stabilization techniques in bilateral fragility fractures of the sacrum (BFFS). Methods. A non-randomized, prospective study was carried out in a level 1 trauma centre. BFFS in 61 patients (mean age 80 years (SD 10); four male, 57 female) were treated surgically with bisegmental transsacral stablization (BTS; n = 41) versus spinopelvic fixation (SP; n = 20). Postoperative full weightbearing was allowed. The outcome was evaluated at two timepoints: discharge from inpatient treatment (TP1; Fitbit tracking, Zebris stance analysis), and ≥ six months (TP2; Fitbit tracking, Zebris analysis, based on modified Oswestry Disability Index (ODI), Majeed Score (MS), and the 12-Item Short Form Survey 12 (SF-12). Fracture healing was assessed by CT. The primary outcome parameter of functional recovery was the per-day step count; the secondary parameter was the subjective outcome assessed by questionnaires. Results. Overall, no baseline differences were observed between the BTS and SP cohorts. In total, 58 (BTS = 19; SP = 39) and 37 patients (BTS = 14; SP = 23) could be recruited at TP1 and TP2, respectively. Mean steps per day at TP1 were median 308 (248 to 434) in the BTS group and 254 (196 to 446) in the SP group. At TP2, median steps per day were 3,759 (2,551 to 3,926) in the BTS group and 3,191 (2,872 to 3,679) in the SP group, each with no significant difference. A significant improvement was observed in each group (p < 0.001) between timepoints. BTS patients obtained better results than SP patients in ODI (p < 0.030), MS (p = 0.007), and SF-12 physical status (p = 0.006). In all cases, CT showed sufficient fracture healing of the posterior ring. Conclusion. Both groups showed significant outcome improvement and sufficient fracture healing. Both techniques can be recommended for BFFS, although BTS was superior with respect to subjective outcome. Step-count tracking represents a reliable method to evaluate the mobility level.

Aims. The aim of this study was to determine the current incidence and epidemiology of humeral diaphyseal fractures. The secondary aim was to explore variation in patient and injury characteristics by fracture location within the humeral diaphysis. Methods. Over ten years (2008 to 2017), all adult patients (aged ≥ 16 years) sustaining an acute fracture of the humeral diaphysis managed at the study centre were retrospectively identified from a trauma database. Patient age, sex, medical/social background, injury mechanism, fracture classification, and associated injuries were recorded and analyzed. Results. A total of 900 fractures (typical 88.9%, n = 800/900; pathological 8.3%, n = 75/900; periprosthetic 2.8%, n = 25/900) were identified in 898 patients (mean age 57 years (16 to 97), 55.5% (n = 498/898) female). Overall fracture incidence was 12.6/100,000/year. For patients with a typical fracture (n = 798, mean age 56 years (16 to 96), 55.1% (n = 440/798) female), there was a bimodal distribution in men and unimodal distribution in older women (Type G). A fall from standing was the most common injury mechanism (72.6%, n = 581/800). The majority of fractures involved the middle-third of the diaphysis (47.6%, n = 381/800) followed by the proximal- (30.5%, n = 244/800) and distal-thirds (n = 175/800, 21.9%). In all, 18 injuries (2.3%) were open and a radial nerve palsy occurred in 6.7% (n = 53/795). Fractures involving the proximal- and middle-thirds were more likely to occur in older (p < 0.001), female patients (p < 0.001) with comorbidities (p < 0.001) after a fall from standing (p < 0.001). Proximal-third fractures were also more likely to occur in patients with alcohol excess (p = 0.003) and to be classified as AO-Orthopaedic Trauma Association type B or C injuries (p < 0.001). Conclusion. This study updates the incidence and epidemiology of humeral diaphyseal fractures. Important differences in patient and injury characteristics were observed based upon fracture location. Injuries involving the proximal- and middle-thirds of the humeral diaphysis should be considered as fragility fractures. Cite this article: Bone Joint J 2020;102-B(11):1475–1483

Osteoporosis is a disease when bone mass and tissue is lost, with a consequent increase in bone fragility and increase susceptibility to develop fracture. The osteoporosis prevalence increases markedly with age, from 2% at 50 years to more than 25% at 80 years. 1. in women. The vast majority of distal radius fractures (DRFs) can be considered fragility fractures. The DRF is usually the first medical presentation of these fractures. With an aging population, all fracture clinics should have embedded screening for bone health and falls risk. DRF is the commonest type of fracture in perimenopausal women and is associated with an increased risk of later non-wrist fracture of up to one in five in the subsequent decade. 2. . According to the national guidelines in managing the fragility fractures of distal radius with regards the bone health review, we, as orthopedic surgeons, are responsible to detect the risky patients, refer them to the responsible team to perform the required investigations and offer the treatment. We reviewed our local database (E-trauma) all cases of fracture distal radius retrospectively during the period from 01/08/2019 to 29/09/2019. We included total of 45 patients who have been managed conservatively and followed up in fracture clinic. Our inclusion criteria was: women aged 65 years and over, men aged 75 years and over with risk factors, patients who are more than 50 years old and sustained low energy trauma whatever the sex is or any patient who has major risk factor (current or frequent recent use of oral or systemic glucocorticoids, untreated premature menopause or previous fragility fracture). We found that 96% of patients were 50 years old or more and 84% of the patients were females. 71% of patients were not referred to Osteoporosis clinic and 11% were already under the orthogeriatric care and 18% only were referred. Out of the 8 referred patients, 3 were referred on 1st appointment, 1 on the 3rd appointment, 1 on discharge from fracture clinic to GP again and 3 were without clear documentation of the time of referral. We concluded that we as trust are not compliant to the national guidelines with regards the osteoporosis review for the DRF as one of the first common presentations of fragility fractures. We also found that the reason for that is that there is no definitive clear pathway for the referral in our local guidelines. We recommended that the Osteoporosis clinic referral form needs to be available in the fracture clinic in an accessible place and needs to be filled by the doctor reviewing the patient in the fracture clinic in the 1st appointment. A liaison nurse also needs to ensure these forms have been filled and sent to the orthogeriatric team. Alternatively, we added a portal on our online database (e-trauma), therefore the patient who fulfils the criteria for bone health review should be referred to the orthogeriatric team to review

This multicentre prospective clinical trial aimed to determine whether early administration of alendronate (ALN) delays fracture healing after surgical treatment of fractures of the distal radius. The study population comprised 80 patients (four men and 76 women) with a mean age of 70 years (52 to 86) with acute fragility fractures of the distal radius requiring open reduction and internal fixation with a volar locking plate and screws. Two groups of 40 patients each were randomly allocated either to receive once weekly oral ALN administration (35 mg) within a few days after surgery and continued for six months, or oral ALN administration delayed until four months after surgery. Postero-anterior and lateral radiographs of the affected wrist were taken monthly for six months after surgery. No differences between groups was observed with regard to gender (p = 1.0), age (p = 0.916), fracture classification (p = 0.274) or bone mineral density measured at the spine (p = 0.714). The radiographs were assessed by three independent assessors. There were no significant differences in the mean time to complete cortical bridging observed between the ALN group (3.5 months (se 0.16)) and the no-ALN group (3.1 months (se 0.15)) (p = 0.068). All the fractures healed in the both groups by the last follow-up. Improvement of the Quick-Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, grip strength, wrist range of movement, and tenderness over the fracture site did not differ between the groups over the six-month period. Based on our results, early administration of ALN after surgery for distal radius fracture did not appear to delay fracture healing times either radiologically or clinically.

Aims. Hip fracture is a common condition of the older, frailer person. This population is also at risk from SARS-CoV-2 infection. It is important to understand the impact of coexistent hip fracture and SARS-CoV-2 for informed decision-making at patient and service levels. Methods. We undertook a systematic review and meta-analysis of observational studies of older (> 60 years) people with fragility hip fractures and outcomes with and without SARS-CoV-2 infection during the first wave of the COVID-19 pandemic. The primary outcome was early (30-day or in-hospital) mortality. Secondary outcomes included length of hospital stay and key clinical characteristics known to be associated with outcomes after hip fracture. Results. A total of 14 cohort and five case series studies were included (692 SARS-CoV-2 positive, 2,585 SARS-CoV-2 negative). SARS-CoV-2 infection was associated with an overall risk ratio (RR) for early mortality of 4.42 (95% confidence interval (CI) 3.42 to 5.82). Early mortality was 34% (95% CI 30% to 38%) and 9% (95% CI 8% to 10%) in the infected and noninfected groups respectively. Length of stay was increased in SARS-CoV-2 infected patients (mean difference (MD) 5.2 days (3.2 to 7.2)). Age (MD 1.6 years (0.3 to 2.9)); female sex (RR 0.83 (95% CI 0.65 to 1.05)); admission from home (RR 0.51 (95% CI 0.26 to 1.00)); presence of dementia (RR 1.13 (95% CI 0.94 to 1.43)); and intracapsular fracture (RR 0.89 (95% CI 0.71 to 1.11)) were not associated with SARS-CoV-2 infection. There were statistically, but not clinically, significantly greater Nottingham Hip Fracture Scores in infected compared with non-infected patients (MD 0.7 (0.4 to 0.9)). Conclusion. SARS-CoV-2 infection is associated with worse outcomes after hip fracture. This is not explained by differences in patient characteristics. These data can be used to support informed decision-making and may help track the impact of widespread adoption of system-level and therapeutic changes in management of the COVID-19 pandemic.

Aims. We assessed the value of the Clinical Frailty Scale (CFS) in the prediction of adverse outcome after hip fracture. Methods. Of 1,577 consecutive patients aged > 65 years with a fragility hip fracture admitted to one institution, for whom there were complete data, 1,255 (72%) were studied. Clinicians assigned CFS scores on admission. Audit personnel routinely prospectively completed the Standardised Audit of Hip Fracture in Europe form, including the following outcomes: 30-day survival; in-hospital complications; length of acute hospital stay; and new institutionalization. The relationship between the CFS scores and outcomes was examined graphically and the visual interpretations were tested statistically. The predictive values of the CFS and Nottingham Hip Fracture Score (NHFS) to predict 30-day mortality were compared using receiver operating characteristic area under the curve (AUC) analysis. Results. Significant non-linear associations between CFS and outcomes were observed. Risk of death within 30 days rose linearly for CFS 1 to 5, but plateaued for CFS > 5. The incidence of complications and length of stay rose linearly for CFS 1 to 4, but plateaued for CFS > 4. In contrast, the risk of new institutionalization rose linearly for CFS 1 to 8. The AUCs for 30-day mortality for the CFS and NHFS were very similar: CFS AUC 0.63 (95% CI 0.57 to 0.69) and NHFS AUC 0.63 (95% CI 0.57 to 0.69). Conclusion. Use of the CFS may provide useful information on outcomes for fitter patients presenting with hip fracture, but completion of the CFS by the admitting orthopaedic team does not appear successful in distinguishing between higher CFS categories, which define patients with frailty. This makes a strong case for the role of the orthogeriatrician in the early assessment of these patients. Further work is needed to understand why patients assessed as being of mild, moderate, and severe frailty do not result in different outcomes. Cite this article: Bone Joint J 2022;104-B(8):980–986

Aims

Current levels of hip fracture morbidity contribute greatly to the overall burden on health and social care services. Given the anticipated ageing of the population over the coming decade, there is potential for this burden to increase further, although the exact scale of impact has not been identified in contemporary literature. We therefore set out to predict the future incidence of hip fracture and help inform appropriate service provision to maintain an adequate standard of care.

Aims. Ankle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest. Methods. A modified Delphi method was used and a group of experts with a vested interest in best practice were invited from the British Foot and Ankle Society (BOFAS), British Orthopaedic Association (BOA), Orthopaedic Trauma Society (OTS), British Association of Plastic & Reconstructive Surgeons (BAPRAS), British Geriatric Society (BGS), and the British Limb Reconstruction Society (BLRS). Results. In the first stage, there were 36 respondents to the survey, with over 70% stating their unit treats more than 20 such cases per year. There was a 50:50 split regarding if the timing of surgery should be within 36 hours, as per the hip fracture guidelines, or 72 hours, as per the open fracture guidelines. Overall, 75% would attempt primary wound closure and 25% would utilize a local flap. There was no orthopaedic agreement on fixation, and 75% would permit weightbearing immediately. In the second stage, performed at the BLRS meeting, experts discussed the survey results and agreed upon a consensus for the management of open elderly ankle fractures. Conclusion. A mutually agreed consensus from the expert panel was reached to enable the best practice for the management of patients with frailty with an open ankle fracture: 1) all units managing lower limb fragility fractures should do so through a cohorted multidisciplinary pathway. This pathway should follow the standards laid down in the "care of the older or frail orthopaedic trauma patient" British Orthopaedic Association Standards for Trauma and Orthopaedics (BOAST) guideline. These patients have low bone density, and we should recommend full falls and bone health assessment; 2) all open lower limb fragility fractures should be treated in a single stage within 24 hours of injury if possible; 3) all patients with fragility fractures of the lower limb should be considered for mobilisation on the day following surgery; 4) all patients with lower limb open fragility fractures should be considered for tissue sparing, with judicious debridement as a default; 5) all patients with open lower limb fragility fractures should be managed by a consultant plastic surgeon with primary closure wherever possible; and 6) the method of fixation must allow for immediate unrestricted weightbearing.

Aims. The purpose of this study was to determine the weightbearing practice of operatively managed fragility fractures in the setting of publically funded health services in the UK and Ireland. Methods. The Fragility Fracture Postoperative Mobilisation (FFPOM) multicentre audit included all patients aged 60 years and older undergoing surgery for a fragility fracture of the lower limb between 1 January 2019 and 30 June 2019, and 1 February 2021 and 14 March 2021. Fractures arising from high-energy transfer trauma, patients with multiple injuries, and those associated with metastatic deposits or infection were excluded. We analyzed this patient cohort to determine adherence to the British Orthopaedic Association Standard, “all surgery in the frail patient should be performed to allow full weight-bearing for activities required for daily living”. Results. A total of 19,557 patients (mean age 82 years (SD 9), 16,241 having a hip fracture) were included. Overall, 16,614 patients (85.0%) were instructed to perform weightbearing where required for daily living immediately postoperatively (15,543 (95.7%) hip fracture and 1,071 (32.3%) non-hip fracture patients). The median length of stay was 12.2 days (interquartile range (IQR) 7.9 to 20.0) (12.6 days (IQR 8.2 to 20.4) for hip fracture and 10.3 days (IQR 5.5 to 18.7) for non-hip fracture patients). Conclusion. Non-hip fracture patients experienced more postoperative weightbearing restrictions, although they had a shorter hospital stay. Patients sustaining fractures of the shaft and distal femur had a longer median length of stay than demographically similar patients who received hip fracture surgery. We have shown a significant disparity in weightbearing restrictions placed on patients with fragility fractures, despite the publication of a national guideline. Surgeons intentionally restrict postoperative weightbearing in the majority of non-hip fractures, yet are content with unrestricted weightbearing following operations for hip fractures.

The purpose of this study was to determine whether there have been changes in the complexity of femoral fragility fractures presenting to our Dunedin Orthopaedic Department, New Zealand, over a period of ten years. Patients over the age of 60 presenting with femoral fragility fractures to Dunedin Hospital in 2009 −10 (335 fractures) were compared with respect to demographic data, incidence rates, fracture classification and treatment details to the period 2018-19 (311 fractures). Pathological and high velocity fractures were excluded. The gender proportion and average age (83.1 vs 83.0 years) was unchanged. The overall incidence of femoral fractures in people over 60 years in our region fell by 27% (p<0.001). Intracapsular fractures (31 B1 and B2) fell by 29% (p=0.03) and stable trochanteric fractures by 56% (p<0.001). The incidence of unstable trochanteric fractures (31A2 and 31A3) increased by 84.5% from 3.5 to 6.4/10,000 over 60 years (p = 0.04). The proportion of trochanteric fractures treated with an intramedullary (IM) nail increased from 8% to 37% (p <0.001). Fewer intracapsular fractures were treated by internal fixation (p<0.001) and the rate of acute total hip joint replacements increased from 13 to 21% (p=0.07). The incidence of femoral shaft fractures did not change significantly with periprosthetic fractures comprising 70% in both cohorts. While there has been little difference in the numbers there has been a decrease in the incidence of femoral fragility fractures likely due to the increasing use of bisphosphonates. However, the incidence of unstable trochanteric fractures is increasing. This has led to the increased use of IM nails which are increasingly used for stable fractures as well. The increasing complexity of femoral fragility fractures is likely to have an impact on implant use, theatre time and cost

Introduction. Ankle fractures in the elderly have been increasing with an ageing but active population and bring with them specific challenges. Medical co-morbidities, a poor soft tissue envelope and a requirement for early mobilisation to prevent morbidity and mortality, all create potential pitfalls to successful treatment. As a result, different techniques have been employed to try and improve outcomes. Total contact casting, both standard and enhanced open reduction internal fixation, external fixation and most recently tibiotalocalcaneal (TTC) nailing have all been proposed as suitable treatment modalities. Over the past five years popular literature has begun to herald TTC nailing as an appropriate and contemporary solution to the complex problem of high-risk ankle fragility fractures. We sought to assess whether, within our patient cohort, the outcomes seen supported the statement that TTC has equal outcomes to more traditional open reduction internal fixation (ORIF) when used to treat the high-risk ankle fragility fracture. Materials & Methods. Results of ORIF versus TTC nailing without joint preparation for treatment of fragility ankle fractures were evaluated via retrospective cohort study of 64 patients with high-risk fragility ankle fractures without our trauma centre. We aimed to assess whether results within our unit were equal to those seen within other published studies. Patients were matched 1:1 based on gender, age, Charlson Comorbidity Index (CCI) and ASA score. Patient demographics, AO/OTA fracture classification, intra-operative and post-operative complications, discharge destination, union rates, FADI scores and patient mobility were recorded. Results. There were 32 patients within each arm. Mean age was 78.4 (TTC) and 78.3 (ORIF). The CCI was 5.9 in each group respectively with mean ASA 2.9 (TTC) and 2.8 (ORIF). There were two open fractures within each group. Median follow up duration was 26 months. Time to theatre from injury was 8.0 days (TTC) versus 3.3 days (ORIF). There was no statistically significant difference in 30-day, one year or overall mortality at final follow up. Kaplan-Meier survivorship analysis did however demonstrate that of those patients who died post-operatively the mean time to mortality was significantly shorter in those treated with TTC nailing versus ORIF (20.3 months versus 38.2 months, p=0.013). There was no statistical difference in the overall complication rate between the two groups (46.9% versus 25%, p=0.12). The re-operation rate was twice as high in patients treated with TTC nailing however this was not statistically significant. There was no statistical difference in the FADI scores at final follow up, 72.1±12.9 (TTC) versus 67.9±13.9 (ORIF) nor post-operative mobility status. Conclusions. Within our study TTC nailing with an unprepared joint demonstrated broadly equivalent results to ORIF in the management of high-risk ankle fragility fractures; this replicates findings of previous studies. We did however observe that mean survival was significantly shorter in the TTC group than those treated with ORIF. We believe this may have been contributed to by a delay to theatre due to TTC stabilisation being treated as a sub-specialist operation in our unit at the time. We propose that both TTC and ORIF are satisfactory techniques to stabilise the frail ankle fracture however, similarly to the other fragility fractures, the priority should be on an emergent operation in a timely fashion in order to minimise the associated morbidity and mortality. Further randomised control studies are needed within the area to establish definitive results and a working consensus

Venous Thromboembolism (VTE) prophylaxis is an essential part of orthopaedic surgeries in preventing life-threatening thromboembolic events such as Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE). Orthopaedic surgery has the highest incidence rate of thromboembolic events as compared to any other surgical specialities, making it an essential component in managing any orthopaedic case. At Queen's Medical Centre (QMC), a major trauma centre in the United Kingdom (UK), sees up to 750 NOF fracture cases annually, making it one of the busiest trauma and orthopaedic centres in the UK. Our study aims to evaluate how VTE Prophylaxis is conducted in a UK Major Trauma Centre for NOF and pelvic fragility fractures and how human factors can improve its efficacy. The Nottingham University Hospitals (NUH) Trust has implemented new guidelines from August 2019 that patients with fragility fractures such as NOF and pelvic fractures are prescribed with 28 days VTE prophylaxis with Enoxaparin, or their own anti-coagulants if risk of thrombosis exceed the risk of bleeding. This is an adaptation from the trust to align their guidelines closer to the NICE 2018 guidelines. We will be evaluating the initial compliance of VTE Prophylaxis, identify and utilise human factors, then re-analyse the department after implementing interventions on the same batch of junior doctors working in the department. Data of 100 patients with fragility fractures were collected, 50 consecutive patients in the pre-intervention window during August 2019 and 50 in the post-intervention window during November 2019. The pre-intervention data had 43 NOF and 7 Pelvic fractures. Our study showed that 93% of NOF fracture and 100% of pelvic fracture received the correct course of VTE prophylaxis. The data was presented at the local department junior doctor academic session. Three simple human factor interventions were implemented over the course of September and October: Education to the trauma and orthopaedic department on the new guideline, extended VTE labels on drug charts for patients with fragility fractures, VTE reminder labels at doctors' stations. Another 50 consecutive patients' data were collected during November 2019. Data shows that 97.8% of NOF (p>0.05) and 60% of pelvic fracture (p>0.05) received the correct course of VTE prophylaxis. Our data has shown an increase in correct VTE prescription for NOF fracture patients, which is the main bulk of our fragility fracture patients whilst we see a drop in pelvic fracture patients. Due to the limited time frame of four months where junior doctors in the UK rotate between specialities, we are only able to collect data during the first month, implement interventions between datasets and collect data on the final month of the four-month rotation. A future bigger study might provide a more significant result on the department. We believe that the key to achieving 100% VTE prophylaxis in the T&O department is optimising human factors, educating junior doctors, who are not orthopaedic trained, with sufficient information of the guidelines, and evidence of the risk and benefits of providing prolonged VTE prophylaxis for orthopaedic patients. In conclusion, we found that QMC, a major trauma centre with high patient volume and turnover, has a high level of compliance with VTE prophylaxis for fragility fractures and it is imperative that utilising human factors will inch the department closer to its goal of 100% VTE compliance

Fragility fractures associated with osteoporosis (OP) reduce quality of life, increase risk for subsequent fractures, and are a major economic burden. In 2010, Osteoporosis Canada produced clinical practice guidelines on the management of OP patients at risk for fractures (Papaioannou et al. CMAJ 2010). We describe the real-world incidence of primary and subsequent fragility fractures in elderly Canadians in Ontario, Canada in a timespan (2011–2017) following guideline introduction. This retrospective observational study used de-identified health services administrative data generated from the publicly funded healthcare system in Ontario, Canada from the Institute for Clinical Evaluative Sciences. The study population included individuals ≥66 years of age who were hospitalized with a primary (i.e. index) fragility fracture (identified using ICD-10 codes from hospital admissions, emergency and ambulatory care) occurring between January 1, 2011 and March 31, 2015. All relevant anatomical sites for fragility fractures were examined, including (but not limited to): hip, vertebral, humerus, wrist, radius and ulna, pelvis, and femur. OP treatment in the year prior to fracture and subsequent fracture information were collected until March 31, 2017. Patients with previous fragility fractures over five years prior to the index fracture, and those fractures associated with trauma codes, were excluded. 115,776 patients with an index fracture were included in the analysis. Mean (standard deviation) age at index fracture was 80.4 (8.3) years. In the year prior to index fracture, 32,772 (28.3%) patients received OP treatment. The incidence of index fractures per 1,000 persons (95% confidence interval) from 2011–2015 ranged from 15.16 (14.98–15.35) to 16.32 (16.14–16.51). Of all examined index fracture types, hip fractures occurred in the greatest proportion (27.3%) of patients (Table). The proportion of patients incurring a second fracture of any type ranged from 13.4% (tibia, fibula, knee, or foot index fracture) to 23% (vertebral index fracture). Hip fractures were the most common subsequent fracture type and the proportion of subsequent hip fractures was highest in patients with an index hip fracture (Table). The median (interquartile range [IQR]) time to second fracture ranged from 436 (69–939) days (radius and ulna index fracture) to 640 (297–1,023) days (tibia, fibula, knee, or foot index fracture). The median (IQR) time from second to third fracture ranged from 237 (75–535) days (pelvis index fracture) to 384 (113–608) days (femur index fracture). This real-world study found that elderly patients in Ontario, Canada incurring a primary fragility fracture from 2011–2015 were at risk for future fractures occurring over shorter periods of time with each subsequent fracture. These observations are consistent with previous reports of imminent fracture risk and the fragility fracture cascade in OP patients (Balasubramanian et al. ASBMR 2016, Toth et al. WCO-IOF-ESCEO 2018). Overall, these data suggest that in elderly patients with an index fragility fracture at any site (with the exception of the radius or ulna), the most likely subsequent fracture will occur at the hip in less than 2 years

To evaluate the effects of 6 and 18 months of abaloparatide (ABL) compared with placebo (PBO) on bone mineral density (BMD) in the acetabular regions of postmenopausal women with osteoporosis (OP). Acetabular bone loss, as may occur in OP, increases risk of acetabular fragility fractures. a. In total hip arthroplasty (THA), low acetabular BMD adversely affects primary stability, osseointegration, and migration of acetabular cups. c. ABL is an osteoanabolic agent for the treatment of men and postmenopausal women with OP at high risk for fracture. Effects of ABL on acetabular BMD are unknown. Hip DXA scans were obtained at baseline, 6, and 18 months from a random subgroup of postmenopausal women (aged 49–86 y) from the phase 3 ACTIVE trial randomized to either ABL 80 µg/d or PBO (n=250/group). Anatomical landmarks were identified in each DXA scan to virtually place a hemispherical shell model of an acetabular cup and define regions of interest corresponding to DeLee & Charnley zones 1 (R1), 2 (R2), and 3 (R3). BMD changes compared to baseline were calculated for each zone. Statistical P values were based on a repeated mixed measures model. BMD in all zones were similar at baseline in the ABL and PBO groups. BMD significantly increased in the ABL group at 6 and 18 months compared with PBO (all P<0.0001 vs PBO). BMD in the PBO group was relatively stable over time. ABL treatment resulted in rapid and progressive increases in BMD of all 3 acetabular zones. Increasing acetabular BMD has the potential to improve acetabular strength, which may reduce risk of acetabular fragility fractures. In bone health optimization prior to THA, increased acetabular BMD via ABL may provide better primary stability and longevity of acetabular cups in postmenopausal women with OP

Fragility ankles fractures in the geriatric population are challenging to manage, due to fracture instability, soft tissue compromise, patient co-morbidities. Traditional management options include open reduction internal fixation, or conservative treatment, both of which are fraught with high complication rates. We aimed to present functional outcomes of elderly patients with fragility ankle fractures treated with tibiotalocalcaneal nails. 171 patients received a tibiotalocalcaneal nail over a six-year period, but only twenty met the inclusion criteria of being over sixty and having poor bone stock, verified by radiological evidence of osteopenia or history of fragility fractures. Primary outcome was mortality risk from co-morbidities, according to the Charlson co-morbidity index (CCI), and patients’ post-operative mobility status compared to pre-operative mobility. Secondary outcomes include intra-operative and post-operative complications, six-month mortality rate, time to mobilisation and union. The mean age was 77.82 years old, five of whom are type 2 diabetics. The average CCI was 5.05. Thirteen patients returned to their pre-operative mobility state. Patients with low CCI are more likely to return to pre-operative mobility status (p=0.16; OR=4.00). Average time to bone union and mobilisation were 92.5 days and 7.63 days, respectively. Mean post-operative AOFAS ankle-hindfoot and Olerud-Molander scores were 53.0 (range 17-88) and 50.9 (range 20-85), respectively. There were four cases of broken distal locking screws, and four cases of superficial infection. Patients with high CCI were more likely to acquire superficial infections (p=0.264, OR=3.857). There were no deep infections, periprosthetic fractures, nail breakages, non-unions. TTC nailing is an effective treatment methodology for low-demand geriatric patients with fragility ankle fractures. This technique leads to low complication rates and early mobilisation. It is not a life-changing procedure, with many able to return to their pre-operative mobility status, which is important for preventing the loss of socioeconomic independence

Aims. COVID-19 represents one of the greatest global healthcare challenges in a generation. Orthopaedic departments within the UK have shifted care to manage trauma in ways that minimize exposure to COVID-19. As the incidence of COVID-19 decreases, we explore the impact and risk factors of COVID-19 on patient outcomes within our department. Methods. We retrospectively included all patients who underwent a trauma or urgent orthopaedic procedure from 23 March to 23 April 2020. Electronic records were reviewed for COVID-19 swab results and mortality, and patients were screened by telephone a minimum 14 days postoperatively for symptoms of COVID-19. Results. A total of 214 patients had orthopaedic surgical procedures, with 166 included for analysis. Patients undergoing procedures under general or spinal anaesthesia had a higher risk of contracting perioperative COVID-19 compared to regional/local anaesthesia (p = 0.0058 and p = 0.0007, respectively). In all, 15 patients (9%) had a perioperative diagnosis of COVID-19, 14 of whom had fragility fractures; six died within 30 days of their procedure (40%, 30-day mortality). For proximal femoral fractures, our 30-day mortality was 18.2%, compared to 7% in 2019. Conclusion. Based on our findings, patients undergoing procedures under regional or local anaesthesia have minimal risk of developing COVID-19 perioperatively. Those with multiple comorbidities and fragility fractures have a higher morbidity and mortality if they contract COVID-19 perioperatively; therefore, protective care pathways could go some way to mitigate the risk. Our 30-day mortality of proximal femoral fractures was 18.2% during the COVID-19 pandemic in comparison to the annual national average of 6.1% in 2018 and the University Hospital Coventry average of 7% for the same period in 2019, as reported in the National Hip Fracture Database. Patients undergoing procedures under general or spinal anaesthesia at the peak of the pandemic had a higher risk of contracting perioperative COVID-19 compared to regional block or local anaesthesia. We question whether young patients undergoing day-case procedures under regional block or local anaesthesia with minimal comorbidities require fourteen days self-isolation; instead, we advocate that compliance with personal protective equipment, a negative COVID-19 swab three days prior to surgery, and screening questionnaire may be sufficient.

Aims. The current global pandemic due to COVID-19 is generating significant burden on the health service in the UK. On 23 March 2020, the UK government issued requirements for a national lockdown. The aim of this multicentre study is to gain a greater understanding of the impact lockdown has had on the rates, mechanisms and types of injuries together with their management across a regional trauma service. Methods. Data was collected from an adult major trauma centre, paediatric major trauma centre, district general hospital, and a regional hand trauma unit. Data collection included patient demographics, injury mechanism, injury type and treatment required. Time periods studied corresponded with the two weeks leading up to lockdown in the UK, two weeks during lockdown, and the same two-week period in 2019. Results. There was a 55.7% (12,935 vs 5,733) reduction in total accident and emergency (A&E) attendances with a 53.7% (354 vs 164) reduction in trauma admissions during lockdown compared to 2019. The number of patients with fragility fractures requiring admission remained constant (32 patients in 2019 vs 31 patients during lockdown; p > 0.05). Road traffic collisions (57.1%, n = 8) were the commonest cause of major trauma admissions during lockdown. There was a significant increase in DIY related-hand injuries (26% (n = 13)) lockdown vs 8% (n = 11 in 2019, p = 0.006) during lockdown, which resulted in an increase in nerve injuries (12% (n = 6 in lockdown) vs 2.5% (n = 3 in 2019, p = 0.015) and hand infections (24% (n = 12) in lockdown vs 6.2% (n = 8) in 2019, p = 0.002). Conclusion. The national lockdown has dramatically reduced orthopaedic trauma admissions. The incidence of fragility fractures requiring surgery has not changed. Appropriate provision in theatres should remain in place to ensure these patients can be managed as a surgical priority. DIY-related hand injuries have increased which has led to an increased in nerve injuries requiring intervention

The widely used Fracture Risk Assessment Tool (FRAX) estimates a 10-year probability of major osteoporotic fracture (MOF) using age, sex, body mass index, and seven clinical risk factors, including prior history of fracture. Prior fracture is a binary variable in FRAX, although it is now clear that prior fractures affect future MOF risk differently depending on their recency and site. Risk of MOF is highest in the first two years following a fracture and then progressively decreases with time – this is defined as imminent risk. Therefore, the FRAX tool may underestimate true fracture risk and result in missed opportunities for earlier osteoporosis management in individuals with recent MOF. To address this, multipliers based on age, sex, and fracture type may be applied to baseline FRAX scores for patients with recent fractures, producing a more accurate prediction of both short- and long-term fracture risk. Adjusted FRAX estimates may enable earlier pharmacologic treatment and other risk reduction strategies. This study aimed to report the effect of multipliers on conventional FRAX scores in a clinical cohort of patients with recent non-hip fragility fractures. After obtaining Research Ethics Board approval, FRAX scores were calculated both before and after multiplier adjustment, for patients included in our outpatient Fracture Liaison Service who had experienced a non-hip fragility fracture between June 2020 and November 2021. Patients age 50 years or older, with recent (within 3 months) forearm (radius and/or ulna) or humerus fractures were included. Exclusion criteria consisted of patients under the age of 50 years or those with a hip fracture. Age- and sex-based FRAX multipliers for recent forearm and humerus fractures described by McCloskey et al. (2021) were used to adjust the conventional FRAX score. Low, intermediate and high-risk of MOF was defined as less than 10%, 10-20%, and greater than 20%, respectively. Data are reported as mean and standard deviation of the mean for continuous variables and as proportions for categorical variables. A total of 91 patients with an average age of 64 years (range = 50-97) were included. The majority of patients were female (91.0%), with 73.6% sustaining forearm fractures and 26.4% sustaining humerus fractures. In the forearm group, the average MOF risk pre- and post-multiplier was 16.0 and 18.8, respectively. Sixteen percent of patients (n = 11) in the forearm group moved from intermediate to high 10-year fracture risk after multiplier adjustment. Average FRAX scores before and after adjustment in the humerus group were 15.7 and 22.7, respectively, with 25% (n = 6) of patients moving from an intermediate risk to a high-risk score. This study demonstrates the clinically significant impact of multipliers on conventional FRAX scores in patients with recent non-hip fractures. Twenty-five percent of patients with humerus fractures and 16% of patients with forearm fractures moved from intermediate to high-risk of MOF after application of the multiplier. Consequently, patients who were previously ineligible for pharmacologic management, now met criteria. Multiplier-adjusted FRAX scores after a recent fracture may more accurately identify patients with imminent fracture risk, facilitating earlier risk reduction interventions

Aims. Periprosthetic fractures (PPFs) around the knee are challenging injuries. This study aims to describe the characteristics of knee PPFs and the impact of patient demographics, fracture types, and management modalities on in-hospital mortality. Methods. Using a multicentre study design, independent of registry data, we included adult patients sustaining a PPF around a knee arthroplasty between 1 January 2010 and 31 December 2019. Univariate, then multivariable, logistic regression analyses were performed to study the impact of patient, fracture, and treatment on mortality. Results. Out of a total of 1,667 patients in the PPF study database, 420 patients were included. The in-hospital mortality rate was 6.4%. Multivariable analyses suggested that American Society of Anesthesiologists (ASA) grade, history of peripheral vascular disease (PVD), history of rheumatic disease, fracture around a loose implant, and cerebrovascular accident (CVA) during hospital stay were each independently associated with mortality. Each point increase in ASA grade independently correlated with a four-fold greater mortality risk (odds ratio (OR) 4.1 (95% confidence interval (CI) 1.19 to 14.06); p = 0.026). Patients with PVD have a nine-fold increase in mortality risk (OR 9.1 (95% CI 1.25 to 66.47); p = 0.030) and patients with rheumatic disease have a 6.8-fold increase in mortality risk (OR 6.8 (95% CI 1.32 to 34.68); p = 0.022). Patients with a fracture around a loose implant (Unified Classification System (UCS) B2) have a 20-fold increase in mortality, compared to UCS A1 (OR 20.9 (95% CI 1.61 to 271.38); p = 0.020). Mode of management was not a significant predictor of mortality. Patients managed with revision arthroplasty had a significantly longer length of stay (median 16 days; p = 0.029) and higher rates of return to theatre, compared to patients treated nonoperatively or with fixation. Conclusion. The mortality rate in PPFs around the knee is similar to that for native distal femur and neck of femur fragility fractures. Patients with certain modifiable risk factors should be optimized. A national PPF database and standardized management guidelines are currently required to understand these complex injuries and to improve patient outcomes.

Introduction. With an aging population, the prevalence of fragility ankle fractures is rising. The surgical management of these injuries is challenging and associated with high rates of complications. The incidence of fragility ankle fractures is currently estimated to be around 150 per 100,000 people annually and is anticipated to rise to around 269 per 100,000 by 2030. The aim of surgery is to restore mobility, preserve function and to prevent complications related to non-weight-bearing and the application of hind foot nail (HFN) seems to provide these advantages. This systematic review aims to investigate the role of HFN in the treatment of fragility ankle fractures. We aim to review the available evidence published on the functional recovery observed in patients following treatment with HFN and the observed complications in the literature. Materials and Methods. A review of the current literature was conducted to identify recent systematic reviews on the use of HFN in the treatment of fragility ankle fractures. Our electronic search included the following databases; Web of Sciences, Cochrane Database of Systematic Review, MEDLINE, CINHAL, and Academic Search Premier. We also conducted a web search using Google Scholar for sake of completeness. Studies published from the inception of data until September 2019 that assess the effectiveness of HFN in patients with osteoporotic ankle fractures were included. Articles meeting the inclusion criteria were read in full and assessed against the eligibility criteria. Results. Six case series and one randomized controlled trial included in our review. The total number of patients included was 194, of them, 145 were females and 49 males. The age range of all cases was 37–98 years (mean 76.39 years). Patients' demographic data, follow-up duration, Postoperative weight-bearing status, postoperative complications, mortality and Olerud and Molander score (OMAS) scores have been obtained in details. Conclusions. The use of HFN have found that it has favorable outcomes regarding early rehabilitation, restoration of function and length of hospital stay. Prospective trials comparing the outcome of patients with fragility ankle fractures treated with HFN vs conventional treatments are warranted, particularly with long periods of follow ups

The Nottingham Hip Fracture Score (NHFS) is validated to predict mortality after fragility neck of femur fractures (NOF). Risk stratification supports informed consent, peri-operative optimisation and case prioritisation. With the inclusion of fragility distal femur fractures (DFF) in the BPT, increasing attention is being placed on the outcome of these injuries. Developing on the lessons learnt over the past decades in NOF management is key. This study assesses the validity of the NHFS in predicting mortality after fragility DFFs. A multi-centre study of 3 high volume fragility fracture units was performed via a retrospective analysis of prospectively collected databases. Patients aged 60 years-of-age who presented with AO 33.A/B/C native DFF, or V.3.A/B periprosthetic DFF over an 86-month period between September 2014 and December 2021 and underwent surgical treatment were eligible for inclusion. Open and/or polytrauma (ISS >15) were excluded. All operations were performed or supervised by Consultant Orthopaedic Surgeons and were reviewed peri-operatively by a 7-day MDT. Patients with a NHFS of gt;=5 were stratified into a high-risk of 30-day mortality cohort, with all others being œlow-risk. 285 patients were eligible for inclusion with 92 considered to be low-risk of 30-day mortality, these tended to be younger female patients admitted from their own homes. 30-day mortality was 0% in the low-risk cohort and 6.2% (12/193) in the high-risk group. 1-year mortality was 8.7% (8/92) and 35.7% (69/193) in the low and high-risk groups respectively. Area Under the Curve (AUC) analyses of Receiver Operator Characteristic (ROC) curves demonstrated the greatest ability to predict mortality at 30-days for the high-risk cohort (0.714). The NHFS demonstrates a good ability to predict 30-day mortality in those patients with a NHFS =5 after a surgically managed fragility DFF. With comparable mortality outcomes to those documented from fragility NOF

Fragility ankle fractures are traditionally managed conservatively or with open reduction internal fixation (ORIF). Tibiotalocalcaneal (TTC) fusion is an alternative option for the geriatric patient. This systematic review and meta-analysis provides a detailed analysis of the functional and clinical outcomes of hindfoot nailing for fragility ankle fractures presented so far in the literature. A systematic search was performed on MEDLINE, EMBASE, Cochrane Library, Scopus, Web of Science, identifying fourteen studies for inclusion. Studies including patients over 60 with a fragility ankle fracture, treated with TTC nail were included. Patients with a previous fracture of the ipsilateral limb, fibular nails, and pathological fractures were excluded. Subgroup analyses were performed according to (1) open vs closed fractures, (2) immediate post-operative FWB vs post-operative NWB, (3) majority of cohort are diabetics vs minority of cohort are diabetics. Meta-regression analyses were done to explore sources of heterogeneity, and publication bias was assessed using Egger's test. The pooled proportion of superficial infection, deep infection, implant failure, malunion, and all-cause mortality was 0.10 (95%CI:0.06-0.16; I2=44%), 0.08 (95%CI:0.06-0.11, I2=0%), 0.11 (95%CI:0.07-0.15, I2=0%), 0.11 (95%CI:0.06-0.18; I2=51%), and 0.27 (95%CI:0.20-0.34; I2=11%), respectively. The pooled mean post-operative OMAS score was 54.07 (95%CI:48.98-59.16; I2=85%). The best-fitting meta-regression model included age and percentage of male patients as covariates (p=0.0263), and were inversely correlated with higher OMAS scores. Subgroup analyses showed that studies with a majority of diabetics had a higher proportion of implant failure (p=0.0340) and surgical infection (p=0.0096), and a lower chance of returning to pre-injury mobility than studies with a minority of diabetics (p=0.0385). Egger's test (p=0.56) showed no significant publication bias. TTC nailing is an adequate alternative option for fragility ankle fractures. However, current evidence includes mainly case series with inconsistent outcome measures reported and post-operative rehabilitation protocols. Prospective RCTs with long follow-up times and large cohort sizes are needed to clearly guide the use of TTC nailing for ankle fractures

Aims. The distal radius is a major site of osteoporotic bone loss resulting in a high risk of fragility fracture. This study evaluated the capability of a cortical index (CI) at the distal radius to predict the local bone mineral density (BMD). Methods. A total of 54 human cadaver forearms (ten singles, 22 pairs) (19 to 90 years) were systematically assessed by clinical radiograph (XR), dual-energy X-ray absorptiometry (DXA), CT, as well as high-resolution peripheral quantitative CT (HR-pQCT). Cortical bone thickness (CBT) of the distal radius was measured on XR and CT scans, and two cortical indices mean average (CBTavg) and gauge (CBTg) were determined. These cortical indices were compared to the BMD of the distal radius determined by DXA (areal BMD (aBMD)) and HR-pQCT (volumetric BMD (vBMD)). Pearson correlation coefficient (r) and intraclass correlation coefficient (ICC) were used to compare the results and degree of reliability. Results. The CBT could accurately be determined on XRs and highly correlated to those determined on CT scans (r = 0.87 to 0.93). The CBTavg index of the XRs significantly correlated with the BMD measured by DXA (r = 0.78) and HR-pQCT (r = 0.63), as did the CBTg index with the DXA (r = 0.55) and HR-pQCT (r = 0.64) (all p < 0.001). A high correlation of the BMD and CBT was observed between paired specimens (r = 0.79 to 0.96). The intra- and inter-rater reliability was excellent (ICC 0.79 to 0.92). Conclusion. The cortical index (CBTavg) at the distal radius shows a close correlation to the local BMD. It thus can serve as an initial screening tool to estimate the local bone quality if quantitative BMD measurements are unavailable, and enhance decision-making in acute settings on fracture management or further osteoporosis screening.

Aims. With the ageing population, fragility fractures have become one of the most common conditions. The objective of this study was to investigate whether microbiological outcomes and fracture-healing in osteoporotic bone is worse than normal bone with fracture-related infection (FRI). Methods. A total of 120 six-month-old Sprague-Dawley (SD) rats were randomized to six groups: Sham, sham + infection (Sham-Inf), sham with infection + antibiotics (Sham-Inf-A), ovariectomized (OVX), OVX + infection (OVX-Inf), and OVX + infection + antibiotics (OVX-Inf-A). Open femoral diaphysis fractures with Kirschner wire fixation were performed. Staphylococcus aureus at 4 × 10. 4. colony-forming units (CFU)/ml was inoculated. Rats were euthanized at four and eight weeks post-surgery. Radiography, micro-CT, haematoxylin-eosin, mechanical testing, immunohistochemistry (IHC), gram staining, agar plating, crystal violet staining, and scanning electron microscopy were performed. Results. Agar plating analysis revealed a higher bacterial load in bone (p = 0.002), and gram staining showed higher cortical bone colonization (p = 0.039) in OVX-Inf compared to Sham-Inf. OVX-Inf showed significantly increased callus area (p = 0.013), but decreased high-density bone volume (p = 0.023) compared to Sham-Inf. IHC staining showed a significantly increased expression of TNF-α in OVX-Inf compared to OVX (p = 0.049). Significantly reduced bacterial load on bone (p = 0.001), enhanced ultimate load (p = 0.001), and energy to failure were observed in Sham-Inf-A compared to Sham-Inf (p = 0.028), but not in OVX-Inf-A compared to OVX-Inf. Conclusion. In osteoporotic bone with FRI, infection was more severe with more bone lysis and higher bacterial load, and fracture-healing was further delayed. Systemic antibiotics significantly reduced bacterial load and enhanced callus quality and strength in normal bone with FRI, but not in osteoporotic bone.

One of the most important sequelae to ageing is osteoporosis and subsequently hip fractures. Hip fractures are associated with major morbidity, mortality and costs. Most patients require surgery to restore mobility. Provision of surgery and its complications is poorly understood in South Africa. Our aim was to collect and report current hip fracture care at four centres in South Africa, as well as reporting surgical and general patient outcomes. A three year retrospective cohort at four centres will be described, focussing on provision of surgical care, mortality, types of surgery and complications. We identified 562 patients who had surgical intervention for fragility fractures, 66% were females. Forty nine percent had open reduction and internal fixation, 28% had hemi-arthroplasty replacement whilst 23% had total hip replacements. Twenty percent of patients had operative intervention within 36 hours of presentation to the emergency department. Mortality was 9% at 30 days. The most common complications were lower respiratory infections (29%), urinary tract infections (21%) and surgical site infections (9%). This is the largest cohort of surgically treated hip fracture from South Africa. Proportions of patients receiving different surgical interventions such as THR are comparable to the broader literature. However a number of key performance indicators such as surgery within 36 hours are challenging to meet. Given the changing demographics of South Africa, this study provides an early insight to contemporary care and may help provide direction for broader national strategies for reporting and improving hip fracture care

Ankle fractures represent the third most common fragility fracture seen in elderly patients following hip and distal radius fractures. Non-operative management of these see complication rates as high as 70%. Open reduction and internal fixation (ORIF) has complication rates of up to 40%. With either option, patients tend to be managed with a non-weight bearing period of six weeks or longer. An alternative is the use of a tibiotalocalcaneal (TTC) nail. This provides a percutaneous treatment that enables the patient to mobilise immediately. This case-series explores the efficacy of this device in a broad population, including the highly comorbid and cognitively impaired. We reviewed patients treated with TTC nail for acute ankle fractures between 2019 and 2022. Baseline and surgical data were collected. Clinical records were reviewed to record any post-operative complication, and post-operative mobility status and domicile. 24 patients had their ankle fracture managed with TTC nailing. No intra-operative complications were noted. There were six (27%) post-operative complications; four patients had loosening of a distal locking screw, one significant wound infection necessitating exchange of nail, and one pressure area from an underlying displaced fracture fragment. All except three patients returned to their previous domicile. Just over two thirds of patients returned to their baseline level of mobility. This case-series is one of the largest and is also one of the first to include cognitively impaired patients. Our results are consistent with other case-series with a favourable complication rate when compared with ORIF in similar patient groups. The use of a TTC nail in the context of acute, geriatric ankle trauma is a simple and effective treatment modality. This series shows acceptable complication rates and the majority of patients are able to return to their baseline level of mobility and domicile

A balanced inflammatory response is important for successful fracture healing. The response of osteoporotic fracture healing is deranged and an altered inflammatory response can be one underlying cause. The objectives of this review were to compare the inflammatory responses between normal and osteoporotic fractures and to examine the potential effects on different healing outcomes. A systematic literature search was conducted with relevant keywords in PubMed, Embase, and Web of Science independently. Original preclinical studies and clinical studies involving the investigation of inflammatory response in fracture healing in ovariectomized (OVX) animals or osteoporotic/elderly patients with available full text and written in English were included. In total, 14 articles were selected. Various inflammatory factors were reported; of those tumour necrosis factor-α (TNF-α) and interleukin (IL)-6 are two commonly studied markers. Preclinical studies showed that OVX animals generally demonstrated higher systemic inflammatory response and poorer healing outcomes compared to normal controls (SHAM). However, it is inconclusive if the local inflammatory response is higher or lower in OVX animals. As for clinical studies, they mainly examine the temporal changes of the inflammatory stage or perform comparison between osteoporotic/fragility fracture patients and normal subjects without fracture. Our review of these studies emphasizes the lack of understanding that inflammation plays in the altered fracture healing response of osteoporotic/elderly patients. Taken together, it is clear that additional studies, preclinical and clinical, are required to dissect the regulatory role of inflammatory response in osteoporotic fracture healing.

For over a decade, bisphosphonate administration has evolved and become the cornerstone of the prevention and treatment of fragility fractures. Millions of post-menopausal women have relied on, and continue to depend on, the long-acting, bone density-maintaining pharmaceutical drug to prevent low-energy fractures. In return, we have seen the number of fragility fractures decrease, along with associated costs and emotional benefits. However, with any drug, there are often concerns with side effects and complications, and this unique drug class is seeing one such complication in atypical subtrochanteric femoral fracture, counterproductive to that which it was designed to prevent. This has created concern over long-term bisphosphonate administration and its potential link to these atypical fractures. There is controversial evidence surrounding such a definitive link, and no protocol for managing these fractures. . This review offers the latest information regarding this rare but increasingly controversial adverse effect and its potential connection to one of the most successful forms of treatment that is available for the management of fragility fractures

We have developed a novel technique to analyse bone, using imaging mass cytometry (IMC) without the constraints of using immunofluorescent histochemistry. IMC can measure the expression of over 40 proteins simultaneously, without autofluorescence. We analysed mitochondrial respiratory chain (RC) protein deficiencies in human bone which are thought to contribute to osteoporosis with increasing age. Osteoporosis is characterised by reduced bone mineral density (BMD) and fragility fractures. Humans accumulate mitochondrial mutations and RC deficiency with age and this has been linked to the changing phenotype in advancing age and age-related disease. Mitochondrial mutations are detectable from the age of 30 onwards, coincidently the age BMD begins to decline. Mitochondria contain their own genome which accumulates somatic variants at around 10 times the rate of nuclear DNA. Once these mutations exceed a threshold, RC deficiency and cellular dysfunction occur. The PolgD257A/D257A mouse model expresses a proof-reading deficient version of PolgA, a mtDNA polymerase. These mice accumulate mutations 3-5 times higher than wild-type mice showing enhanced levels of age-related osteoporosis and RC deficiency in osteoblasts. Bone samples were analysed from young and old patients, developing a protocol and analysis framework for IMC in bone tissue sections to analyse osteoblasts in-situ for RC deficiency. Samples from the femoral neck of 10 older healthy volunteers aged 40 – 85 were compared with samples from young patients aged 1-19. We have identified RC complex I defect in osteoblasts from 6 of the older volunteers, complex II defects in 2 of the older volunteers, complex IV defect in just 1 older volunteer, and complex V defect in 4 of the older volunteers. These observations are consistent with the PolgD257A/D257A mouse-model and suggest that RC deficiency, due to age-related pathogenic mitochondrial DNA mutations, may play a significant role in the pathogenesis of human age-related osteoporosis

It is known that Osteoporosis is the pathology of bone mass and tissue loss resulting in an increase of fragility, risk of fracture occurrence, and risk of fracture recurrence. We noted there was no definitive pathway in our last audit, therefore recommended: availability of the Osteoporosis clinic referral form in an accessible place, the form be filled by the doctor reviewing the patient in the first fracture clinic, and a liaison nurse to ensure these forms were filled and sent to the Osteoporosis clinic. This second audit analyses our Trust's response to these recommendations and effect achieved in Osteoporosis care. We reviewed our local data base from the 7/27/2020 – 10/2/2021 retrospectively for distal radius fractures who were seen in fracture clinic. We analysed a sample size of 59 patients, excluding patients who had already commenced bone protection medications. 67.7% of our patients had neither been on bone protection medications nor recorded referrals and 13.5% were already on bone protection medications when they sustained the fragility fracture. Ten out of the 51 patients were offered referral to the osteoporosis clinic, and one refused. This makes 20% (10 out of 50) of the patients had completed referrals. In comparison, in our first audit, 11% had already been on bone protection medications and 18% had completed referrals. The second cycle showed a slight increase in compliance. Majority of the referrals were completed by Orthopaedic Consultants in both audits and ana awareness increase noted among non-consultants in starting the referral process. Based on our analysis, our Trust has a slight improvement in commencing bone protection medications, associated with slight improvement in completing referrals to the Osteoporosis clinic. Despite our recommendations in the first audit, there is still no easily accessible definitive pathway to ensure our Trust's patients have timely access to bone protection and continued care at the Osteoporosis clinic. We recommend streamlining our recommendations to have a more effective approach in ensuring our Trust meets national guidelines. We will implement a Yes or No question assessment for patients visiting clinic in our electronic database which should assist in referral completions

BACKGROUND. Ideal treatment of displaced femoral neck fragility fractures in the previously ambulatory patient remains controversial. Treating these patients with total hip arthroplasty has improved patient reported outcomes and reduced rates of revision surgery compared to those treated with hemiarthroplasty. However, possible increased risk of dislocation remains a concern with total hip arthroplasty. The anterolateral and direct anterior approaches to total hip replacement have been applied in the femoral neck fracture population to minimize dislocation rates. However, the anterolateral approach has been associated with abductor injury and increased rates of heterotopic ossification while the anterior approach has been associated with peri-prosthetic femur fracture, lateral femoral cutaneous nerve injury, and wound complications. The Supercapsular Percutaneously Assisted (SuperPATH) approach was developed to minimize disruption of the capsule and short-external rotators in an effort to reduce the risk of dislocation and assist in quicker recovery in the elective hip arthroplasty setting. To achieve this, the SuperPATH technique allows the femur to be prepared in situ and the acetabulum to be reamed percutaneously once the femoral head is removed. This study investigates the post-operative time to ambulation, length of stay, discharge destination, and early dislocation rate of previously ambulatory patients with a displaced femoral neck fragility fracture that were treated with a total hip arthroplasty via the SuperPATH technique. METHODS. A retrospective chart review was performed of previously ambulatory patients consecutively treated for a displaced femoral neck fragility fracture with a total hip replacement using the SuperPATH technique. Thirty-five patients were included in the study and examined for demographic data, time to ambulation, length of stay, major and minor complications during their hospital stay. Phone interviews were conducted to check for dislocation events. RESULTS. Thirty-five patients were included in the study with an average age of 75.7 years old (range 51–95). Patients spent an average of 5.35 ± 1.61 days in the hospital and were discharged on post-operative day 3.6 ±1.38. 89% of patients were able to stand and ambulate by post-operative day 1, and 97% of patients were able to stand and ambulate before discharge from the hospital. 26% of patients were able to be discharged home, 46% were discharged to in-patient rehabilitation, 23% were discharged to a skilled nursing facility, and one patient was discharged to hospice. There were no iatrogenic femoral fractures caused, no incidents of symptomatic heterotopic bone formation, and no superficial or deep wound infections. 88.5% of patients had adequate follow up averaging 370.6 ±235.18 days, with no dislocation events observed. CONCLUSION. These early results indicate that minimally invasive total hip arthroplasty utilizing the SuperPATH technique is a safe and effective treatment for displaced femoral neck fragility fractures in the previously ambulatory patient. Additionally, this technique allows for early ambulation without an increased risk of dislocation

We aimed to audit the results of one stop fragility fracture risk assessment service at fracture clinic for non-hip fractures in 50–75 years old patients at Newcastle General Hospital. Currently, fewer than 30% of patients with fragility fractures benefit from secondary prevention in the form of comprehensive risk assessment and bone protection because of multifactorial reasons. We have a fragility fracture risk assessment service staffed by an Osteoporosis Specialist Nurse equipped with a DEXA scanner located at the fracture clinic itself. We carried out a retrospective audit of 349 patients of 50–75 years with suspected non-hip fractures referred from A& E Department from October 2006 to September 2007. Patients over 75 years were excluded because as per NICE guidelines, they should receive bone protection without need of a DEXA scan. Out of these 349 patients with suspected fractures, 171 had fragility fractures. Median age was 64 years. 69 patients had humerus fracture, 65 had forearm fracture and 23 patients had ankle fracture and 14 had metatarsal fractures. Fracture risk assessment was carried out in 120 (70%) patients. Thirty Seven (31%) patients had osteoporosis and bone protection was recommended to GP. 38 (32%) had osteopenia and lifestyle advice was provided. 45 (37%) had normal axial bone densitometry. 90% patients had DEXA scan at the same time of fracture clinic appointment. Patients with male gender, undisplaced fracture and fewer fracture clinic appointments were more likely to miss fracture risk assessment. Our experience suggests that locating fragility fracture risk assessment service co-ordinated by an Osteoporosis Specialist Nurse at fracture clinic is an efficient way of providing secondary prevention for patients with fragility fractures. This can improve team communication, eliminate delay and improve patient compliance because of ‘One Stop Shop’ service at the time of fracture clinic appointment

Age-related fragility fractures are highly correlated with the loss of bone integrity and deteriorated morphology of the osteocytes. Previous studies have reported low-magnitude high-frequency vibration(LMHFV) promotes osteoporotic diaphyseal fracture healing to a greater extent than in age-matched normal fracture healing, yet how osteoporotic fractured bone responds to the mechanical signal has not been explored. As osteocytes are prominent for mechanosensing and initiating bone repair, we hypothesized that LMHFV could enhance fracture healing in ovariectomized metaphyseal fracture through morphological changes and mineralisation in the osteocyte Lacuno-canalicular Network(LCN). As most osteoporotic fractures occur primarily at the metaphysis, an osteoporotic metaphyseal fracture model was established. A total of 72 six-month old female Sprague-Dawley rats (n=72) were obtained(animal ethical approval ref: 16–037-MIS). Half of the rats underwent bilateral ovariectomy(OVX) and kept for 3 months for osteoporosis induction. Metaphyseal fracture on left distal femur was created by osteotomy and fixed by a plate. Rats were then randomized to (1) OVX+LMHFV(20 mins/day and 5 days/week, 35Hz, 0.3g), (2) OVX control, (3) SHAM+LMHFV, (4) SHAM control. Assessments of morphological structural changes, functional markers of the LCN(Scanning Electron Microscopy, FITC-Imaris, immunohistochemistry), mineralization status(EDX, dynamic histomorphometry) and healing outcomes(X-ray, microCT, mechanical testing) were performed at week 1, 2 and 6 post-fracture. One‐way ANOVA with post-hoc test was performed. Statistical significance was set at p < 0.05. Our results showed LMHFV could significantly enhance the morphology of the LCN. There was a 65.3% increase in dendritic branch points(p=0.03) and 93% increase in canalicular length(p=0.019) in the OVX-LMHFV group at week 2 post-fracture. Besides, a similar trend was also observed in the SHAM+LMHFV group, with a 43.4% increase in branch points and 53% increase in canaliculi length at week 2. A significant increase of E11 and DMP1 was observed in the LMHFV groups, indicating the reconstruction of the LCN. The decreasing sclerostin and increasing FGF23 at week 1 represented the active bone formation phase while the gradual increase at week 6 signified the remodelling phase. Furthermore, Ca/P ratio, mineral apposition rate and bone formation rate were all significantly enhanced in the OVX+LMHFV group. The overall bone mineral density in BV was significantly raised in the OVX+LMHFV group at week 2(p=0.043) and SHAM+LMHFV at week 6(p=0.04). Quantitative analysis of microCT showed BV/TV was significantly increased at week 2 in OVX+LMHFV group(p=0.008) and week 6(p=0.001) in both vibration groups. In addition, biomechanical testing revealed that the OVX+LMHFV group had a significantly higher ultimate load(p=0.03) and stiffness(p=0.02) at week 2. To our best knowledge, this is the first report to illustrate LMHFV could enhance osteocytes' morphology, mineralisation status and healing outcome in a new osteoporotic metaphyseal fracture animal model. Our cumulative data supports that the mechanosensitivity of bone would not impair due to osteoporosis. The revitalized osteocyte LCN and upregulated osteocytic protein markers implied a better connectivity and transduction of signals between osteocytes, which may foster the osteoporotic fracture healing process through an enhanced mineralisation process. This could stimulate further mechanistic investigations with potential translation of LMHFV to our fragility fracture patients

Surgical treatment of fragility sacrum fractures with percutaneous sacroiliac (SI) screw fixation is associated with high failure rates in terms of screw loosening, cut-through and turn-out. The latter is a common cause for complications, being detected in up to 20% of the patients. The aim of this study was to develop a new screw-in-screw concept and prototype implant for fragility sacrum fracture fixation and test it biomechanically versus transsacral and SI screw fixations. Twenty-seven artificial pelves with discontinued symphysis and a vertical osteotomy in zone 1 after Denis were assigned to three groups (n = 9) for implantation of their right sites with either an SI screw, the new screw-in-screw implant, or a transsacral screw. All specimens were biomechanically tested to failure in upright position with the right ilium constrained. Validated setup and test protocol were used for complex axial and torsional loading, applied through the S1 vertebral body. Interfragmentary movements were captured via optical motion tracking. Screw motions in the bone were evaluated by means of triggered anteroposterior X-rays. Interfragmentary movements and implant motions in terms of pull-out, cut-through, tilt, and turn-out were significantly higher for SI screw fixation compared to both transsacral screw and screw-in-screw fixations. In addition, transsacral screw and screw-in-screw fixations revealed similar construct stability. Moreover, screw-in-screw fixation successfully prevented turn-out of the implant, that remained at 0° rotation around the nominal screw axis unexceptionally during testing. From biomechanical perspective, fragility sacrum fracture fixation with the new screw-in-screw implant prototype provides higher stability than with the use of one SI screw, being able to successfully prevent turn-out. Moreover, it combines the higher stability of transsacral screw fixation with the less risky operational procedure of SI screw fixation and can be considered as their alternative treatment option

Abstract. Objectives. Osteoporotic fractures tend to be more challenging than fractures in healthy bone and the efficacy of metal screw fixation decreases with decreasing bone mineral density making it more difficult for such screws to gain purchase. This leads to increased complication rates such as malunion, non-union and implant failure (1). Bioresorbable polymer devices have seen clinical success in fracture fixation and are a promising alternative for metallic devices but are rarely used in the osteoporotic population. To address this, we are developing a system that may allow osteoporotic patients to avail of bioresorbable devices (2) but it is important to establish if patients have any reservations about having a plastic resorbable device instead of a metal one. Therefore the aim of this study was to explore the acceptability of bioresorbable fracture fixation devices to people with osteoporosis. Methods. A cross sectional descriptive study was conducted in a UK wide population using convenience sampling. An online survey comprising nine survey questions and nine demographic questions was developed in Microsoft Teams and tested for face validity in a small pilot study (n=6). Following amendments and ethical approval, the survey was distributed by the Royal Osteoporosis Society on their website and social media platforms. People were invited to take part if they lived in the UK, were over 18 years old and had been diagnosed with osteoporosis. The survey was open for three weeks in May 2023. Responses were analysed using descriptive statistics. Results. There were 112 responses. Eight participants had not been diagnosed with osteoporosis and therefore did not meet the study criteria. Of the remaining 104, 102 were female and 2 were male and 102 were white (2 chose not to disclose their ethnicity). The majority of participants were aged 55–64 (34.6%) or 65–74 (37.5%), were college/university educated (38.5%) and had previously sustained a fragility fracture (52.9%). Only 3.9% of participants had heard of bioresorbable fracture fixation devices compared to 62.5% for metal devices. Most people were unsure if they would trust one type of device over the other (58.7%) and would ask for more information if their surgeon were to suggest using a bioresorbable device to fix their fracture (61.5%). The most commonly reported concerns were about device safety and efficacy: toxicity of the degradation products and the device breaking down too early before the fracture had healed. Two participants cited environmental concerns about increased use of plastics as a reason they would decline such a device. Conclusions. As expected, participants had little to no knowledge of bioresorbable polymer fixation devices. In general, they were willing to be guided by their surgeon but would require supporting information on the safety and efficacy of their long-term use. The results of this study show that it will be important to have relevant and understandable information to give patients when recommending these devices as treatments to ensure and support a shared-decision approach to patient care.

Purpose: Recognizing Osteoporosis and Its Consequences in Québec revealed that 73% of women 50y and over are not provided anti-fracture therapy following fragility fracture. This study’s objectives were to determine predictors of osteoporosis (OP) diagnosis (DX) and treatment (TX) 6 to 8 months after fragility fracture. Method: At phase 1, women were recruited at cast or out-patient clinics within 16 weeks post-fracture. Consenting patients answered a short questionnaire classifying them as experiencing a fragility or traumatic fracture; no reference to the association between fracture and OP was made and no investigation or intervention was proposed. At phase 2, 6–8 months post-fracture, the women completed a questionnaire on demographic features, clinical characteristics and risk factors for OP. The DX (informed of OP and/or BMD measurement with diagnosis of OP) and TX (bisphosphonates, raloxifene, nasal calcitonin or teriparatide) rates of OP were determined via this questionnaire. This analysis included only women with a fragility fracture who were not receiving OP TX at phase 1. Results: Of the 1273 women completing phase 1, 1001 (79%) sustained a fragility fracture; 818 were untreated at phase 1 and completed the phase 2 questionnaire. Overall, 79% of these participants had not received a DX of osteoporosis or were without OP TX at phase 2. The highest rate of DX and TX of OP occurred 0–5 months post-fracture and decreased considerably thereafter. In multivariate analyses, the results of BMD tests before or after the fracture event (p< 0.0001) and mobility problems (p=0.03) were the only variables that influenced the DX of OP. BMD test results were the strongest predictor (p< 0.0001) of TX followed by the fracture site (hip, femur and pelvis; p=0.015) and administration of vitamin D supplements at the time of fracture (p=0.035). No other risk factors for OP significantly influenced the DX or TX rate. No demographic or clinical features or OP risk factors were significantly associated with the decision to refer women for BMD testing post-fracture. Conclusion: Although fragility fracture represents a greater risk of future fragility fracture than low BMD, physicians based their decision to treat on BMD and not the clinical event (fragility fracture)

Cigarette smoking has a negative impact on the skeletal system by reducing bone mass and increasing the risk of fractures through its direct or indirect effects on bone remodeling. Recent evidence shows that smoking causes an imbalance in bone turnover, making bone vulnerable to osteoporosis and fragility fractures. In addition, cigarette smoking is known to have deleterious effects on fracture healing, as a positive correlation has been shown between the daily number of cigarettes smoked and years of exposure to smoking, although the underlying mechanisms are not fully understood. Smoking is also known to cause several medical and surgical complications responsible for longer hospital stays and a consequent increase in resource consumption. Smoking cessation is, therefore, highly advisable to prevent the onset of metabolic bone disease. However, some of the consequences appear to continue for decades. Based on this evidence, the aim of our work was to assess the impact of smoking on the skeletal system, particularly bone fractures, and to identify the pathophysiological mechanisms responsible for the impairment of fracture healing. Because smoking represents a major public health problem, understanding the association between cigarette smoking and the occurrence of bone disease is necessary in order to identify potential new targets for intervention

Purpose. To describe the implication of Family Physicians (FPs) in the management of osteoporosis revealed by a fragility fracture. Method. The impact and costs of fractures is straining the health system. A better collaboration between specialists and FPs should improve the evaluation and treatment of affected patients. Since January 2007, the OPTIMUS initiative is an attempt to reach that objective in the Estrie area of the Province of Quc. With OPTIMUS, rates of appropriate treatment of osteoporosis at one year in previously untreated patients more than double (53% vs 20%). In OPTIMUS, FPs remain responsible for investigation and treatment of their patients after identification of a bone fragility fracture. A coordinator based in orthopaedists outpatient clinics identifies fragility fractures in patients older than 50 y.o., informs them about bone fragility and its link to osteoporosis, and spurs them to contact their FPs to get treated; the importance of persistence on treatment is reinforced during phone follow ups. Initially and when patients remain untreated upon follow up, the coordinator sends a letter to the patients FP about the occurrence of the fracture, its predictive value for future fractures, and the need for investigation and treatment. This represents a personalized form of continuous medical education for FPs, in the hope that FPs become leaders in the prevention of fragility fractures. To evaluate the perception of FPs about OPTIMUS, we performed a mail survey targeting FPs reached at least once by OPTIMUS. Results. The survey was sent to a total of 212 FPs. One hundred and nine (51.4%) answered. Of these, 97 (89%) agreed that a fragility fracture is an indication for treatment of osteoporosis; 56 (51%) agreed that OPTIMUS had helped them take charge of osteoporosis; and 105 (96.3%) were Satisfied or Very Satisfied of the OPTIMUS initiative. Conclusion. Because of this high level of acceptance, we propose to put into place a more elaborate intervention including a fall prevention program that will be managed by nurse coordinators in 16 FP Groups (GMF); these 16 Groups include 178 of the 360 FPs of the area. The FPs practicing in GMF are also involved in teaching to colleagues, residents and medical students; we expect an exponential effect on the practice of FPs over the years. We believe this enhanced intervention will improve the quality of life and autonomy of the patients while decreasing their rate of fractures

Orthopedic surgeons treat numerous patients in whom osteoporosis (OP) is an important factor: inflammatory arthritides (rheumatoid arthritis); sports medicine (the anorexic, amenorrhoeic female athlete); in consultation to renal, transplant and cardiac units; patients on corticosteroids, as well as others. Orthopedic procedures in patients who have osteoporotic bone require special techniques and precautions. A common example is hip replacement, where, through endosteal resorption, the medullary canal is large, cortices are thin, and the risk of femoral fracture and a poor outcome is higher. The commonest interface of orthopedic surgery with OP is in the management of fractures. In North America, most orthopedic surgeons manage fractures in hospital and in the fracture clinic, where typically 3%–8% of patient visits are for classic fragility fractures. Traumatic fractures also commonly occur in osteoporotic bone. The yield of screening for OP in orthopedic wards and clinics, targeting fragility fracture patients, is much higher than screening in a general population. Published guidelines based on Level I evidence indicate that fragility fracture patients are at highest risk of future hip fractures, which often occur within one year of index fragility fracture, and that preventive treatment is economical and safe. Treatment prevents 30–50% of hip fractures in high risk groups. Unfortunately, less than 20% of fragility fracture patients generally receive appropriate OP care, in multiple studies in developed countries. There is a growing international focus on developing care delivery systems that will promote consistent OP investigation and treatment in the inpatient and outpatient orthopedic environment. In Ontario, Canada, an Osteoporosis Exemplary Care Program was initiated in 2003 to identify, educate, evaluate, refer, and treat female (> 40 years) and male (> 50 years) fragility fracture patients for OP. In the first year of the program, over 95% of inpatients and outpatients were appropriately diagnosed, treated, or referred for OP care. Success resulted from the presence of a dedicated coordinator and cooperation by orthopedic surgeons and residents, technologists, allied health professionals and administrative staff. Regional, national and international orthopedic associations have developed initiatives designed to improve processes of care for OP in the orthopedic environment

An audit was carried out to assess the management of patients with fragility fractures in fracture clinic and primary care. NICE guidelines advise these patients require treatment for osteoporosis if 75 years or older, and a DEXA scan if below this age. Distal radius and proximal humeral fractures were identified in a retrospective review of letters from 10 fracture clinics. Current medication of all patients ≥ 75 years was accessed and DEXA scan requests identified for patients < 75 years. There were 69 fragility fractures: 53 distal radius and 16 proximal humerus. 4 letters (6%) mentioned fragility fracture and advised treatment and 3 (3%) correctly advised a DEXA scan. Only 3 of 25 (10%) patients ≥ 75yrs not previously on osteoporosis medication had treatment started by their GPs. 3 of a possible 29 (10%) patients < 75 years were referred for a DEXA scan. A text box highlighting fragility fractures and NICE guidelines was added to all clinic letters for patient ≥ 50 years old. Re-audits showed an improvement in management of these fractures, with 45% of patients ≥ 75 years being started on treatment and 39% of patients < 75 years being referred for a DEXA scan

Introduction: Osteoporosis is a skeletal disorder characterised by decreased bone mineral density (BMD) and a subsequent increased risk of fragility fractures. This disease is commonly associated with postmenopausal females with an increasing incidence into later life, over 50% of females over 80 have osteoporosis. At the opposite spectrum of life, decreased BMD is traditionally associated with the female athletic triad, with hormonal imbalance leading to skeletal insufficiency. Considered a “silent disease” until a fracture occurs, as orthopaedic surgeons we must be able to identify those at risk of osteoporosis and refer promptly for dual energy x-ray absorptiometry (DEXA) scanning to prevent future fragility fractures in this specific patient cohort. Methods: We carried out an epidemiological analysis of all female patients under the age of 30 referred for DEXA scanning in a university teaching hospital over a 3 year period. We analysed mode of referral, risk factors, T-score and subsequent fractures with an aim to highlight an underestimated level of osteopenia/osteoporosis in the younger patient. Results: We identified 102 patients eligible for our study, with a mean age of 25.34 (Range- 17–29). As per the World Health Organisation (WHO) osteopenia was defined as osteopenia as a T-Score between −1 and −2.5, with osteoporosis below −2.5. The mean T score of these patients was −1.037 (range −3.2 to 2.4). Medical teams initiated the majority of referrals (77%), followed by General Practitioners (17%), Gynaecologists (4%), Paediatricians (1%) and Surgeons(1%). Risk factors included excess steroid use for medical conditions (41%), decreased body mass index (BMI) (27%), ceoliac disease (12%) and radiological evidence of osteopenia (7%). 34% of these patients had suffered a fall with 12% of patients suffering from a fragility fracture. Conclusion: We identified a definite cohort of young female patients who had a mean T-score within the levels for osteopenia. Over one third had suffered a fall and 12% had suffered a fragility fracture despite a young age. With ever increasing patient numbers in both fracture and orthopaedic clinics and increased pressure on resources, it is imperative that we still take thorough histories to identify those young female patients that are at risk of osteoporosis. With appropriate follow up and investigations, they can be started on necessary treatment and prevent subsequent fragility fractures, the incidence of which appears to be underestimated

Introduction and Objective. Geriatric patients with a fragility fracture of the hip (FFH) are especially prone to sarcopenia with poor functional outcomes and quality of life. We assessed the prevalence of sarcopenia in older South African patients with FFH. Risk factors for sarcopenia were also investigated. Materials and Methods. From August 1 to November 30, 2018, all older patients with FFH were invited to participate. Sarcopenia was diagnosed based on the revised criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). Handgrip strength (HGS) and muscle strength were assessed. Muscle quantity was determined by dual-energy X-ray absorptiometry. Demographic information was collected, and 25-hydroxyvitamin D (25[OH]D) status was determined. Results. Of the 100 hip fracture cases, 65 were enrolled, and 52% (34/65) were sarcopenic (women: 62%; men: 38%). HGS accurately identified sarcopenia (sensitivity and specificity: 100%). Patients >80 years of age had a prevalence of sarcopenia twice (18/21 [83%]) that of younger patients (18/44 [36%]). Women with sarcopenia were smaller than those without (weight: p < 0.001; height: p < 0.001; body mass index: p¼0.018). Low 25(OH)D was almost universally present, with median 25(OH)D levels significantly lower in the patients with sarcopenia (27 nmol/L [interquartile range {IQR}: 20–39] vs. 40 nmol/L [IQR: 29–53]). Several risk factors, including advanced age; female sex; a smaller body size, especially among women; limited physical activity; and low 25(OH)D levels, were identified. Conclusions. The accuracy of HGS testing in this cohort underscores EWGSOP2's recommendation that muscle strength is key to sarcopenia. Further study and follow-up are required to determine the clinical relevance of sarcopenia among FFH patients. The prevalence of sarcopenia in our FFH population is high. Sarcopenia is associated with poor patient outcomes following surgical intervention. Orthopaedic surgeons should therefore be cognisant of the presentation and associated risk of sarcopenia as our patient populations age

Tranexamic acid (TXA) is an inexpensive antifibrinolytic. Currently there are no national guidelines in the UK that promote the use of TXA in femoral fragility fracture (FFF) management. The aim of the study was to determine whether intra-operative intravenous TXA affects the requirement for post-operative blood transfusion following FFF surgery. A prospective non-randomized case-control study of consecutive FFF admitted to the study centre was performed. 361 patients were included in the study (mean age 81.4yrs; mean BMI 23.5; 73.7% female). TXA was given at the discretion of the operating surgeon, with 178 (49%) patients receiving TXA. Patient demographics, surgical management, peri-operative haemoglobin (Hb) and haematocrit, intravenous TXA use, and requirement for blood transfusion were recorded prospectively. Percentage fall in Hb from preoperative level was calculated at postoperative day one. Calculated-blood-loss (CBL) was determined using the Nadler and Gross formulae. The groups were well matched in terms of patient demographics, injury types and surgical management. The requirement for postoperative blood transfusion was significantly reduced in the TXA group: 15/178 (8.4%) compared to 58/183 (31.7%) (p<0.001; Chi square). TXA significantly reduced both the percentage fall in Hb (mean difference 4.3%, p<0.001) and the CBL (mean difference -222ml, p<0.001). There was no difference in venous thrombosis embolism events between the groups. Intra-operative intravenous TXA during the surgical management of FFF significantly reduced rate of transfusion, CBL and the percentage drop in HB

Purpose: Only 20% of women presenting with fragility fracture are subsequently investigated for Osteoporosis (OP). Blurred lines of responsibility between the orthopedic surgeons (OS) and the general practitioners may partly explain this situation. OPTIMUS is a 3 year health management program, lead by an OS and a rheumatologist, whose objective is to improve the rate of initiation of and persistence on treatment of OP in patients sustaining a fragility fracture visiting an OS at the Centre hospitalier universitaire de Sherbrooke. Method: All outpatients aged 50 years and older in which a fragility fracture is suspected by the OS are informed by a nurse practitioner about the OPTIMUS program. The first 200 patients seen at the Hôtel-Dieu site of the CHUS represent the control group. Inpatients with hip fragility fracture are evaluated by a rheumatologist. After signed consent, outpatient participants are randomized to one out of two intervention groups: The Minimal Intervention group includes nurse counseling and written general information transmitted to both patient and treating physician. Same information is given in the Intensive Intervention group. Blood tests and osteodensitometry are also performed and results transmitted to the treating physician along with personalized guidelines for treatment of the patient’s OP. In both interventions, patients are reached by phone at fixed intervals. Additional rounds of intervention are repeated as needed to increase the rates and persistence of appropriate treatment. Results: Over the first 6 months, the OS team identified 300 patients, 30% of which suffered from hip fracture. Acceptance rates to OPTIMUS management program were close to 95% with direct contact as compared to 50% with delayed phone contact. 5% of outpatients could not name a treating physician and thus had to be seen in rheumatology. The results during the first 18 months of the project will assess the feasibility of OPTIMUS’ interventions. Conclusion: There is a substantial care gap in the management of OP, despite the availability of diagnostic modalities and effective treatment. Involving orthopedic surgeons as key leaders of a multidisciplinary team implementing a systematic approach to identify patient with OP should help to close this care gap

Introduction: The incidence of osteoporosis is increasing as the population ages. Amongst the recommended treatment modalities for osteoporosis is the use of bisphosphonates. The National Osteoporosis Foundation (U.S.A.) recommends DEXA scanning prior to commencing treatment with bisphosphonate therapy. However, in the Irish setting the availability of DEXA scanning is often limited. We hypothesised that a high percentage of elderly women presenting with fragility fractures of the distal radius (following a simple fall from standing height) had underlying osteoporosis. As such, the initiation of treatment with bisphosphonates prior to obtaining a DEXA scan may be warranted in this patient cohort. Aim: To assess the incidence of osteoporosis in a continuous cohort of women over 60 years of age presenting with fractures of the distal radius. Patients and Methods: All female patients aged > 60 years old presenting to the fracture service over a five month period with distal radial fragility fractures were evaluated. Exclusion criteria included:. non-English speakers. non-resident in Ireland. previous diagnosis of osteoporosis or commenced on treatment for osteoporosis. not fit to attend for DEXA scan. not willing to participate in the study. 100 consecutive patients presenting to the fracture service with distal radial fragility fractures were prospectively identified. Data was collected, including body mass index (BMI), risk factors for osteoporosis, and the OST risk index calculated. A DEXA scan was then performed on the patient’s hips and lumbar spine. Results: The mean patient age was 74.3 (95%CI + 10.6) years. Mean BMI was 17.3 kg/m2. The mean Osteoporosis Self-assessment Tool (OST) index score was 0.65 correlating with a moderate risk for osteoporosis. The mean T score for the patients’ hips was −2.0 while that for the lumbar spine was −1.7. 64% of patients were osteoporotic with a T score of less than −2.5. Conclusions A significant incidence of osteoporosis was noted in the study cohort. It is imperative that orthopaedic surgeons recognise the high incidence of osteoporosis in the elderly female population presenting with fragility fractures. The high morbidity and mortality associated with hip and vertebral fractures in this population may be prevented by early treatment of underlying osteoporosis

To discover whether orthopaedic surgeons follow the BOA guidelines for secondary prevention of fragility fractures, a retrospective audit on neck of femur fractures treated in our hospital in October/November 2003 was carried out. There were 27 patients. Twenty-six patients (96%) had full blood count measured. LFT and bone-profile were measured in 18 patients (66%). Only nine patients (30%) had treatment for osteoporosis (calcium and vitamin D). Only one patient was referred for DEXA scan. Steps were taken to create better awareness of the BOA guidelines among junior doctors and nurse practitioners. In patients above 80 years of age it was decided to use abbreviated mental score above 7 as a clinical criterion for DEXA referral. A hospital protocol based on BOA guidelines was made. A re-audit was conducted during the period August-October 2004, with 37 patients. All of them had their full blood count and renal profile checked (100%). The bone-profile was measured in 28 (75.7%) and LFT in 34 (91.9%) patients. Twenty-four patients (65%) received treatment in the form of calcium + Vit D (20) and bisphosphonate (4). DEXA scan referral was not indicated in 14 patients as 4 of them were already on bisphosphonates and 10 patients had an abbreviated mental score of less than 7. Among the remaining 23 patients, nine (40%) were referred for DEXA scan. This improvement is statistically significant (p=0.03, chi square test). The re-audit shows that, although there is an improvement in the situation, we are still below the standards of secondary prevention of fragility fractures with 60% of femoral fragility fracture patients not being referred for DEXA scan. A pathway lead by a fracture liaison nurse dedicated to osteoporotic fracture patients should improve the situation

Purpose: To demonstrate that Rush pin is safe and effective in selected fragility ankle fractures. Introduction: Fragility ankle fracture is increasing proportionately to their age. It produces not only clinical challenge due to multiple co morbidities but also a challenge to heal the fracture and particularly the skin. We found that early minimal intervention by stabilizing the lateral column with a rush nail is safe, beneficial and acceptable practice in selected cases. Material & Method: Retrospective case notes & X-rays review of fragility ankle fractures between 1st of January 2005 to 31. st. of August 2008 selection using the criteria below. ✓ Closed Ankle Fracture. ✓ Elderly or fragility fracture. ✓ Minimal invasive ORIF. Results:. Seven patients found. Mean age: 78.2. M: F – 1:5. ASA CLASS: 3–4. All patients had ankle fracture with fragile or damaged skin. All operated within 10 days of injury, including those who were on warfarin or significant medical problems. All underwent closed reduction and or percutaneous medial malleolar fixation and stabilization of the lateral column with Rush Pin through a stab incision under x-ray control. A lightweight plaster was applied for 4–6 weeks. All fracture healed in a acceptable position without any skin complication. One patient who had pre operative ulcer also healed. Discussion/Conclusion: Minimally invasive treatment has no surgical wound complication. All fracture healed in a satisfactory position. All discharged after mean follow up of 6 month. One death due to unrelated cause after 5 weeks of operation. Rush pin fixation in fragility fracture is a useful and safe methods of treatment in selected group

Aims: Secondary prevention in patients suffering neck of femur fractures is an effective but under utilised strategy in reducing subsequent fragility fractures. Published BOA guidelines recommend patients aged 75 or over with fragility fractures should receive bisphosphonates, falls risk assessment, and vitamin D supplements if there are concerns regarding deficiency. This audit aimed to determine the effectiveness of implementing secondary prevention strategies in patients admitted with neck of femur fractures. Methods: Patients aged 75 or above admitted to a local trauma unit with neck of femur fractures were identified over a two-year period. In-hospital mortality was recorded. Discharge letters for the remaining patients were obtained. Data was collected on whether patients were commenced on bisphosphonates and vitamin D supplements in hospital, or whether advice was given for these therapies to be initiated in the community. Patients undergoing falls risk assessment prior to discharge were also noted. Results: Overall 549 patients met the inclusion criteria. Eighty patients died during admission giving an in-hospital mortality rate of 14.6% per year. A further 238 patients were excluded due to missing data leaving 231 patients in the final study population. Mean age was 84.4 yr (range 75–97 yr) and 77.9% (n=180) were female. Bisphosphonate therapy was commenced or recommended in 22.9% (n=53), vitamin D supplements in 46.3% (n=107), and 16.5% (n=38) underwent falls risk assessment. Only 4.3% (n=10) were commenced on bisphosphonates and underwent falls risk assessment. Conclusions: Despite evidence that secondary prevention is effective in reducing subsequent fragility fractures our findings demonstrate these strategies are poorly implemented with less than one in twenty patients receiving the recommended falls assessment and antiresorptive therapy. A standardised discharge letter for patients with neck of femur fractures would provide more effective communication between hospitals and primary care thereby assisting the implementation of secondary prevention strategies

Background: By the end of the current Bone and Joint Decade (2000–2010) the World Health Organisation predicts that 55% of post-menopausal women will have osteoporosis, as defined by fragility fracture and / or BMD. Volume aside, fragility fractures also represent a significant technical challenge in operative care. Current aggressive medical management is aimed to minimize the resource impact of this pandemic. Study Design: This prospective study of 3000 consecutive fractures treated in a Level 1 trauma unit identified 977 fragility fractures requiring operative management, 803 of which were in patients over the age of 65 years. In every case the GP was informed of the diagnosis of osteoporosis and appropriate recommendations were made regarding medical management. We present the demographic features of this population and the resource impact of their management. We also examine the outcome of our efforts to improve care of the elderly with osteoporotic fractures, as all GP’s were contacted 6 months following discharge to determine the uptake of medical treatment as recommended. Materials and Methods: Our computerized operative database was utilized to prospectively collect demographic and operative data on all 977 patients. All medical charts were examined to identify medications on admission, GP contact details and other relevant information. GP’s were contacted by telephone and post to determine patient 6-month mortality and the uptake in the use of recommended medication. Data represents the mean ± SD. Results: Of the 803 patients over the age of 65 years, the average age was 80.5 ± 7.5 years, with a 75% female preponderance. 14% of these had had a previous wrist or vertebral insufficiency fracture, while 2.2% had a previous contralateral hip fracture. Hip fractures accounted for 70% (566 patients) of fragility fractures with 25% AMP, 24% Bipolar, 51% DHS. There were 121 wrist fractures. On admission 23% of hip fracture patients were resident in a Nursing Home. Despite the relatively large number with previous fracture (16.2%) only 3.4% were taking calcium / vitamin D supplementation while only 2.1% were on anti-resorptive therapy, eg a bisphosphonate. The median interval between admission and operation was 1 calendar day with a range of 1–10 days. 57% of all cases were performed outside of routine trauma lists. The average length of stay for this hip fracture population was 11.5 days with a further 16.5 days spent at a step down facility. Only 14.8% went directly home. Of 240 GP’s contacted, 74% replied resulting in complete follow-up data on 730 patients. The inpatient mortality rate was 5.8% while that at 6 months follow up was 19%. By this time 54% of hip fracture patients were living in Nursing Homes. The number of patients taking only calcium / vitamin D was 4%, a bisphosphonate alone 6%, while the use of both had risen dramatically to 16%. Conclusions: To our knowledge this is the largest reported study documenting the epidemiology, demography and short-term follow-up of hip fractures in an elderly Irish population. Such data is essential to appropriately plan for the impending national health crisis consequent to the predicted dramatic rise in the elderly population with bone fragility. In a short time, we have achieved significant success in improving awareness and treatment of osteoporosis in the elderly following hip fracture

Fractures of the neck of femur are common in the older adult with significant morbidity and mortality rates. This patient cohort is associated with frailty and multiple complex medical and social needs requiring a multidisciplinary team to provide optimal care. The aim of this study was to assess the outcomes at 5 years following implementation of a collaborative service between the Orthopaedic and Geriatric departments of Southland Hospital in 2012. Retrospective data was collected for patients aged 65 years and older who were admitted with a fragility hip fracture. Data was collated for 2011 (pre-implementation) and 2017 (post-implementation). Demographics and ASA scores were recorded. We assessed 30-day and 1-year mortality, surgical data, length of stay and complications. There were 74 patient admissions in 2011 and 107 in 2017. Mean age at surgery was 84.2 years in 2011 and 82.6 years in 2017 (p>0.05). Between the 2011 and 2017 groups there has been a non-significant reduction in length of stay on the orthopaedic ward (9.8 days vs 7.5 days, p=0.138) but a significant reduction in length of stay on the rehabilitation ward (19.9 vs 9 days, p<0.001). There was a significant decrease in frequency of patients with a complication (71.6% vs 57%, p=0.045) and a marginal reduction in number of complications (p=0.057). Through logistic regression controlling for age, sex and ASA score, there was a reduction in the odds of having a complication by 12% between 2011 and 2017 (p<0.001). There was no difference in mortality between the groups. The orthogeriatric model of care at Southland Hospital appears to have reduced both the frequency of complications and length of stay on the rehabilitation ward 5 years after its implementation. This is the first study in New Zealand demonstrating medium-term post-implementation follow-up of what is currently a nationally accepted standard model of care

Introduction. Open fragility ankle fractures involve complex decision making. There is no consensus on the method of surgical management. Our aim in this study was to analyse current management of these patients in a major trauma centre (MTC). Materials & Methods. This cohort study evaluates the management of geriatric (≥65years) open ankle fractures in a MTC (November 2020–November 2022). The method, timing(s) and personnel involved in surgical care were assessed. Weightbearing status over the treatment course was monitored. Patient frailty was measured using the clinical frailty score (CFS). Results. There were 35 patients, mean age 77 years (range 65–97 years), 86% female. Mean length of admission in the MTC was 26.4 days (range 3–78). Most (94%) had a low-energy mechanism of injury. Only 57% of patients underwent one-stage surgery (ORIF n=15, hindfoot nail n=1, external frame n=4) with 45% being permitted to fully weightbear (FWB). Eleven (31.4%) underwent two-stage surgery (external fixator; ORIF), with 18% permitted to FWB. Of those patients with pre-injury mobility, 12 (66%) patients were able to FWB following definitive fixation. Delay in weightbearing ranged from 2–8weeks post-operatively. Seven patients (20%) underwent an initial Orthoplastic wound debridement. Ten patients (28.6%) required plastic surgery input (split-skin grafts n=9, local or free flaps n=3), whereby four patients (40%) underwent one stage Orthoplastic surgery. Eighteen (51.4%) patients had a CFS ≥5. Patients with a CFS of ≥7 had 60% 90-day mortality. Only 17% patients had orthogeriatrician input during admission. Conclusions. These patients have high frailty scores, utilise a relatively large portion of resources with multiple theatre attendances and protracted ward occupancy in an MTC. Early FWB status needs to be the goal of treatment, ideally in a single-staged procedure. Poor access to orthogeriatric care for these frail patients may represent healthcare inequality

Aims. This is a multicentre, prospective assessment of a proportion of the overall orthopaedic trauma caseload of the UK. It investigates theatre capacity, cancellations, and time to surgery in a group of hospitals that is representative of the wider population. It identifies barriers to effective practice and will inform system improvements. Methods. Data capture was by collaborative approach. Patients undergoing procedures from 22 August 2022 and operated on before 31 October 2022 were included. Arm one captured weekly caseload and theatre capacity. Arm two concerned patient and injury demographics, and time to surgery for specific injury groups. Results. Data was available from 90 hospitals across 86 data access groups (70 in England, two in Wales, ten in Scotland, and four in Northern Ireland). After exclusions, 709 weeks' of data on theatre capacity and 23,138 operations were analyzed. The average number of cases per operating session was 1.73. Only 5.8% of all theatre sessions were dedicated day surgery sessions, despite 29% of general trauma patients being eligible for such pathways. In addition, 12.3% of patients experienced at least one cancellation. Delays to surgery were longest in Northern Ireland and shortest in England and Scotland. There was marked variance across all fracture types. Open fractures and fragility hip fractures, influenced by guidelines and performance renumeration, had short waits, and varied least. In all, nine hospitals had 40 or more patients waiting for surgery every week, while seven had less than five. Conclusion. There is great variability in operative demand and list provision seen in this study of 90 UK hospitals. There is marked variation in nearly all injuries apart from those associated with performance monitoring. There is no evidence of local network level coordination of care for orthopaedic trauma patients. Day case operating and pathways of care are underused and are an important area for service improvement. Cite this article: Bone Jt Open 2023;4(6):463–471

Objective: To critically appraise the use of hindfoot nailing as an alternative treatment for fragility fractures of the ankle. Summary of background data: Ankle fractures are common. The peak incidence now lies in women between the ages of 75 and 84. These fractures are inherently unstable and it is known that anatomical reduction and stable fixation leads to a rapid return of function. Although this is usually achieved by open reduction and plate and screw fixation, in older patients poor bone quality and compromised wound healing can lead to unacceptably high complication rates. Conservative management of these patients also has its problems with anatomical congruity being difficult to achieve and maintain. Method: We reviewed 13 patients who underwent minimally invasive intramedullary nailing to fuse the tibiotalocalcaneal joint as primary or revision treatment for an ankle fracture. Olerud and Molander Scale, and SF36 were used as outcome measures. Results: There were 12 females and 1 male with a mean age of 81.5 (range 64 to 93). One nail was revised after 22 days due to valgus deformity and one patient suffered a minor wound (breakdown / infection). Half of the patients were discharged in the first two weeks after the operation. They all achieved pain free full weight bearing on the fractured ankle and gained a comparable function to their pre-operative state. The mean follow up period was 9 months (range of 2 – 62 months). Conclusion: Minimally invasive tibiotalocalcaneal fusion is a very useful and successful way of restoring function following a fragility fracture of the ankle. We recommend its use in the cases of fragility fracture of the ankle with poor soft tissue

Treat to target is the use of a physiologic marker as a monitor of effectiveness or compliance to an intervention. A recent example has been the progressive use of CTX-1 (Marker of osteoclastic activity) as a surrogate of bone resorptive activity in osteoporosis treatment. CTX-1 levels were demonstrated to be inversely related to drug efficacy in the suppression of bone resorption. As far as fragility fractures are concerned, no reference value of CTX-1 for any index fracture sites was found in the literature. In order to prevent subsequent fractures, efforts to better manage this chronic disease are to be explored. The main objective of this study was to compare and validate the use of serum CTX-1 to the perceived compliance to treatment. Five hundred and forty three patients (men and women) 40 years of age or older who had been treated for a fragility fracture were enrolled. The purpose of this study was to correlate the measurement of CTX-1 with the perceived compliance to treatment of patients at the time of fracture and at six, 12 and 18 months after initiation of treatment. Our secondary objectives were to evaluate two different CTX-1 suppression target levels (CTX-1< 0.3 ng/mL and CTX-1<0.2 ng/mL), to determine CTX-1 values according to fracture sites, and to explore the profile of patients with subsequent fractures. Considering index fractures, compliant patients under treatment at baseline had lower CTX-1 levels than non-compliant patients (p=0.052). Patients who were compliant to treatment at six, 12 and 18 months also had lower CTX-1 levels than non-compliant patients (p=0.000). When index fractures were divided into fracture sites, regardless of CTX-1 suppression target level (i.e. CTX-1< 0.3 or 0.2 ng/mL), significant CTX-1 suppression was observed in non-hip and non-vertebral (NHNV) fractures at six, 12 and 18 months (p0.05). No clinically relevant difference was observed between the profile of patients with and without subsequent fractures. The correlation between serum CTX-1 at the time of fracture and at six, 12, 18 months and the perceived compliance to treatment was validated for NHNV fractures supporting the concept of the available treatments and their effects on bone remodeling for this type of fracture. The correlation was not validated for hip neither for vertebral fracture. There was no correlation between CTX-1 levels and subsequent fracture risk

Aim. The treatment of fracture-related infections (FRI) focuses on obtaining fracture healing and eradicating infection to prevent osteomyelitis. Treatment guidelines include removal, exchange, or retention of the implants used according to the stability of the fracture and the time from the infection. Infection of a fracture in the process of healing with a stable fixation may be treated with implant retention, debridement, and antibiotics. Nonetheless, the retention of an intramedullary nail is a potential risk factor for failure, and it is recommended to exchange or remove the nail. This surgical approach implies additional life-threatening risks in elderly fragile hip fracture patients. Our study aimed to analyze the results of implant retention for the treatment of infected nails in elderly hip fracture patients. Methods. Our retrospective analysis included patients 65 years of age or older with an acute fracture-related infection treated with implant retention from 2012 to 2020 in 6 Spanish hospitals with a minimum 1-year follow-up. Patients that required open reduction during the initial fracture surgery were excluded. Variables included in our analysis were patient demographics, type of fracture, date of FRI diagnosis, causative microorganism, and outcome. Treatment success was defined as fracture healing with infection eradication without the need for further hospitalization. Results. A total of 48 patients were identified. Eight patients with open reduction were excluded and 11 did not complete a 1-year follow-up. Out of the 29 remaining patients, the mean age was 81.5 years, with a 21:9, female to male ratio. FRI was diagnosed between 10 and 48 days after initial surgery (mean 26 days). Treatment success was achieved in 24 patients (82.7%). Failure was objectivated in polymicrobial infections or infections caused by microorganisms resistant to antibiofilm antibiotics. Seven patients required more than one debridement with a success rate of 57%. Twelve patients had an infection diagnosed after 21 days from the initial surgery and implant retention was successful in all of them. Conclusion. Our results suggest implant retention is a valid therapeutic approach for fracture-related infection in elderly hip fracture patients treated by closed reduction and intramedullary nailing

Objectives. Bisphosphonates are widely used as first-line treatment for primary and secondary prevention of fragility fractures. Whilst they have proved effective in this role, there is growing concern over their long-term use, with much evidence linking bisphosphonate-related suppression of bone remodelling to an increased risk of atypical subtrochanteric fractures of the femur (AFFs). The objective of this article is to review this evidence, while presenting the current available strategies for the management of AFFs. Methods. We present an evaluation of current literature relating to the pathogenesis and treatment of AFFs in the context of bisphosphonate use. Results. Six broad themes relating to the pathogenesis and management of bisphosphonate-related AFFs are presented. The key themes in fracture pathogenesis are: bone microdamage accumulation; altered bone mineralisation and altered collagen formation. The key themes in fracture management are: medical therapy and surgical therapy. In addition, primary prevention strategies for AFFs are discussed. Conclusions. This article presents current knowledge about the relationship between bisphosphonates and the development of AFFs, and highlights key areas for future research. In particular, studies aimed at identifying at-risk subpopulations and organising surveillance for those on long-term therapy will be crucial in both increasing our understanding of the condition, and improving population outcomes.

A prior fragility fracture is one of the strongest predictors for a subsequent one, and this should be a target for secondary fracture prevention. All injured patients admitted to the emergency floor, Ume̊ University Hospital, Sweden, were registered. Between 1993–2004, there were 113,668 injury events, including 29,190 fracture events (one or more fractures at the same time), of whom 12,635 patients were _ 50 years. 1,994 of them had at least two fracture events; 500 had 3; 131 had 4; 35 had 5; and 11 had _ 6 fracture events. Mean age at the baseline fracture was 72.2 years and 75.5 at the second one. Thus, over 50 years of age, not less than 37% of all fractures were serial fractures, and 20% of the patients are serial fracturers. Hip and radius fracture were the most common ones, but 20% were fractures not traditionally labelled as fragility fractures. However, since more than 78% were caused by falls in the same level, most presumably have a fragility component. The interval between the two first fractures was longer than reported in several previous studies, mostly on patients participating in clinical trials. However, our material is population-based and unselected, since there is just one trauma facility in the area, and the general population is healthier than in-hospital or trial patients. On the other hand, there is a cut-off bias, so the interval is likely to be even longer. Interestingly, the difficult-to-treat hip fracture was the second common baseline fracture, the most common subsequent one, and hip-hip fractures were the most common combination, not less than 8.5% of the serial fractures. It is therefore clinically important to use the information provided by the fracture event, a fragility fracture may actually be regarded as a biomechanical test or a natural experiment. Trauma units, therefore, have an onus to screen for risk factors and inform patients about the treatment options, and to organize fracture liaison services. This seems to be especially cost-efficient for our oldest and frailest patients, but alas this is rarely done. A similar neglect of secondary prophylaxis and treatment after cardiovascular disorders would be an outrage! Secondary prevention is especially important since serial fractures are so common, often preventable, having a high impact on health-related quality of life

Purpose: To evaluate the impact of the Osteoporosis Exemplary Care Program (OECP) on orthopaedic surgeons’ practice patterns at St. Michael’s Hospital. Methods: A chart audit was performed to collect data on two groups of 54 patients identified with fragility fractures. The intervention group consisted of patients treated during the first four months of the OECP, while the control (pre-intervention) group consisted of age, sex, and fracture-type matched patients treated prior to implementation of the OECP. Characteristics of the intervention and control groups were compared using chi-square tests. Multivariable logistic regression analysis was then performed to identify significant correlates of OP care. Results: Preliminary results from 54 matched pairs (108 patients in total) indicate that the OECP group was more likely to have OP risk or OP diagnosis documented (unadjusted OR 2.49; 95% CI 1.05–5.87), as well as to be referred for further investigation of OP (unadjusted OR 3.08; 95% CI 1.37–6.91) or to receive treatment or follow-up related to OP (unadjusted OR 9.01; 95% CI 3.77–21.54). As one surgeon was known to have been providing a high level of OP care prior to implementation of the OECP, the analysis was repeated after removing his patients. In addition, the analysis was repeated after removing patients who were already being treated for OP at the time of their fragility fracture. In both cases, larger increases in the likelihood of OP documentation and care were observed. Through multivariable analysis, age and fracture type (i.e. wrist vs. hip) were found to be significant correlates of having received OP care for patients with fragility fractures treated prior to implementation of the OECP. Following implementation of the OECP, there were no significant correlates of receiving OP care. Conclusions: Preliminary results indicate that the OECP had a significant impact on orthopedic surgeons’ practice patterns. Following implementation of the OECP all patients were equally likely to receive appropriate referral, treatment, and follow-up whereas, prior to implementation of the program, age and fracture type affected the likelihood that a patient would receive such care.

Proximal humerus fractures are the third most common fragility fractures with treatment remaining challenging. Mechanical fixation failure rates of locked plating range up to 35%, with 80% of them being related to the screws perforating the glenohumeral joint. Secondary screw perforation is a complex and not yet fully understood process. Biomechanical testing and finite element (FE) analysis are expected to help understand the importance of various risk factors. Validated FE simulations could be used to predict perforation risk. This study aimed to (1) develop an experimental model for single screw perforation in the humeral head and (2) evaluate and compare the ability of bone density measures and FE simulations to predict the experimental findings. Screw perforation was investigated experimentally via quasi-static ramped compression testing of 20 cuboidal bone specimens at 1 mm/min. They were harvested from four fresh-frozen human cadaveric proximal humeri of elderly donors (aged 85 ± 5 years, f/m: 2/2), surrounded with cylindrical embedding and implanted with a single 3.5 mm locking screw (DePuy Synthes, Switzerland) centrally. Specimen-specific linear µFE (ParOSol, ETH Zurich) and nonlinear explicit µFE (Abaqus, SIMULIA, USA) models were generated at 38 µm and 76 µm voxel sizes, respectively, from pre- and post-implantation micro-Computed Tomography (µCT) images (vivaCT40, Scanco Medical, Switzerland). Bone volume (BV) around the screw and in front of the screw tip, and tip-to-joint distance (TJD) were evaluated on the µCT images. The µFE models and BV were used to predict the experimental force at the initial screw loosening and the maximum force until perforation. Initial screw loosening, indicated by the first peak of the load-displacement curve, occurred at a load of 64.7 ± 69.8 N (range: 10.2 – 298.8 N) and was best predicted by the linear µFE (R. 2. = 0.90), followed by BV around the screw (R. 2. = 0.87). Maximum load was 207.6 ± 107.7 N (range: 90.1 – 507.6 N) and the nonlinear µFE provided the best prediction (R. 2. = 0.93), followed by BV in front of the screw tip (R. 2. = 0.89). Further, the nonlinear µFE could better predict screw displacement at maximum force (R. 2. = 0.77) than TJD (R. 2. = 0.70). The predictions of non-linear µFE were quantitatively correct. Our results indicate that while density-based measures strongly correlate with screw perforation force, the predictions by the nonlinear explicit µFE models were even better and, most importantly, quantitatively correct. These models have high potential to be utilized for simulation of more realistic fixations involving multiple screws under various loading cases. Towards clinical applications, future studies should investigate if explicit FE models based on clinically available CT images could provide similar prediction accuracies

Objectives. Bisphosphonates (BP) are the first-line treatment for preventing fragility fractures. However, concern regarding their efficacy is growing because bisphosphonate is associated with over-suppression of remodelling and accumulation of microcracks. While dual-energy X-ray absorptiometry (DXA) scanning may show a gain in bone density, the impact of this class of drug on mechanical properties remains unclear. We therefore sought to quantify the mechanical strength of bone treated with BP (oral alendronate), and correlate data with the microarchitecture and density of microcracks in comparison with untreated controls. Methods. Trabecular bone from hip fracture patients treated with BP (n = 10) was compared with naïve fractured (n = 14) and non-fractured controls (n = 6). Trabecular cores were synchrotron scanned and micro-CT scanned for microstructural analysis, including quantification of bone volume fraction, microarchitecture and microcracks. The specimens were then mechanically tested in compression. Results. BP bone was 28% lower in strength than untreated hip fracture bone, and 48% lower in strength than non-fractured control bone (4.6 MPa vs 6.4 MPa vs 8.9 MPa). BP-treated bone had 24% more microcracks than naïve fractured bone and 51% more than non-fractured control (8.12/cm. 2. vs 6.55/cm. 2. vs 5.25/cm. 2. ). BP and naïve fracture bone exhibited similar trabecular microarchitecture, with significantly lower bone volume fraction and connectivity than non-fractured controls. Conclusion. BP therapy had no detectable mechanical benefit in the specimens examined. Instead, its use was associated with substantially reduced bone strength. This low strength may be due to the greater accumulation of microcracks and a lack of any discernible improvement in bone volume or microarchitecture. This preliminary study suggests that the clinical impact of BP-induced microcrack accumulation may be significant. Cite this article: A. Jin, J. Cobb, U. Hansen, R. Bhattacharya, C. Reinhard, N.

Introduction: Fragility fractures are taking up an increasing amount of resources within Trauma departments. Women have a 1 in 3, men a 1 in 12 lifetime risk of sustaining an osteoporotic fracture with a previous fracture being the strongest independent predictor of sustaining a further fragility fracture, often within one year. Secondary prevention is therefore particularly important. Many guidelines give advice on secondary prevention in women, but very few mention men even though men have a higher morbidity and mortality after hip fractures. Methods: A retrospective review was carried out including 91 patients (48 females, 43 males) who were admitted with a fragility hip fracture between March 2003 and April 2004. Data about age, sex, investigations and medication were collected from the case notes, GP surgeries and the bone densitometry database. Investigations and treatment were compared with current guidelines (SIGN 2003, NICE 2005). Data was analysed using SPSS Version 13.0. Results: 33% of women and only 8% of men < 75 years of age were investigated for osteoporosis (DEXA scan) following their hip fracture (Fishers Exact Test, p = 0.32). In patients ≥ 75 years 25% of women and only 6% of men were treated with bisphosphonates (χ. 2. = 4.18, p < 0.05). There was also a statistically significant difference in overall treatment including bisphosphonates and calcium/vitamin D between the sexes (χ. 2. = 6.81, p < 0.05). Discussion: This study shows that there is a great need for improvement in secondary prevention of osteoporotic fragility fractures in both sexes, but men are far less likely to receive investigations and treatment than women. It is therefore essential to include recommendations for men in future guidelines and to increase awareness of male osteoporosis. Orthopaedic surgeons should take responsibility for initiating the process of secondary prevention

Patients most at risk of osteoporosis are post-menopausal women. However, for many such women, presentation of osteoporosis is only made following their first fragility fracture. Often in the UK, osteoporosis investigation occurs following discharge, and any subsequent secondary prevention starts in the community. This may result in patients with osteoporosis not being investigated or not receiving correct prophylactic treatment. 143 post-menopausal women (av. age 77.7 years) starting secondary osteoporosis prophylaxis following fragility fractures requiring operative intervention were included in this retrospective study. Osteoporosis was defined by DEXA scan using the WHO criteria (122 hip fractures and 21 wrist fractures), following the UK's national guidelines for osteoporosis prophylaxis. Treatment was started following discussion and explanation of treatment with each patient, and either commenced by the surgical team during the acute hospital admission with the fracture, or in an out-patient setting within 6 weeks of the fracture by an orthopaedic specialist nurse. To check compliance, either the patient themselves or the patients' family physician was contacted. Results showed that 120 of the women (83.9%, 102 hip fractures, and 18 wrist fractures) were still compliant with secondary osteoporosis prophylaxis at an average follow-up of 200 days (5 hip fractures lost to follow-up, 0 wrist fractures). 12 women with hip fractures died (0 wrist fractures), and 6 women stopped taking their prophylaxis (3 hip fractures, 3 wrist fractures): 4 for medical reasons, and 2 for unknown reasons. No women sustained further fractures. Few studies have previously investigated compliance of osteoporosis secondary prevention, and our results compare favorably. We therefore recommend the prompt commencement of secondary prevention treatment by the orthopaedic surgical team following osteoporotic fractures

Bones are thought to become fragile with advancing age due to a loss of mass and structure. However, there are important aspects of bone fragility and fracture that cannot be explained simply by a loss of bone: 30% of all patients told they have healthy bone based on bone mineral density (BMD) measurements go on to fracture. It has been suggested that increased fracture risk might also be due to ageing at the nanoscale, which might deteriorate the overall mechanical properties of a bone. However, it is not clear how mechanics at the level of the collagen-mineral matrix relate to mechanical properties of the whole bone, or whether nano-mechanics contribute to fracture risk. In order to answer these questions our group is developing state of the art methods for analysing the structure and function of the collagen mineral matrix under loading. To image the collagen mineral matrix we obtained beam time on a synchrotron particle accelerator at the Diamond Light Source (Didcot, UK). Electrons are accelerated to near light speed by powerful electromagnets, then slowed to create high energy monochromatic X-Ray beams. Through a combination of X-Ray computed tomography and X-Ray diffraction we have been able to image the collagen/mineral matrix. Furthermore, using in situ loading experiments it has been possible to visualise collagen fibrillar sliding and mineral crystal structure. Our group is analysing how age related changes in nano-structure affect bone mechanical behaviour. As well as comparing fragility fracture patients with ‘healthy’ age matched controls to investigate whether ageing at the nano-scale could increase fracture risk. We are also assessing the effect of common treatments for bone fragility (e.g. bisphosphonate) on nano-mechanics. Unfortunately the expense and high radiation dose associated with synchrotron imaging prevents the technology from being adapted for patients. Therefore the next step will be to identify and test tools that can be used to indirectly assess bone chemistry and mechanical properties at point of care (e.g. laser spectroscopy and indentation). The data could be used to improve the diagnosis, monitoring and treatment of bone fragility

Introduction. The purpose of this study was to establish whether men and women with a fragility hip fracture were equally investigated and treated for osteoporosis. Methods. A retrospective review was carried out including 91 patients (48 females, 43 males) who were admitted with a fragility hip fracture between March 2003 and April 2004. Data about age, sex, investigations and medication were collected from the case notes, GP surgeries and the bone densitometry database. Investigations and treatment were compared with current guideline recommendations (SIGN 2003, NICE 2005). Data were analysed using SPSS Version 13.0. Results. According to the guidelines patients < 75 years of age should be investigated and patients > 75 years should be treated for osteoporosis. In our review 33% of women and only 8% of men < 75 years were investigated with a DEXA scan following their hip fracture (Fishers Exact Test, p = 0.32). In patients > 75 years 25% of women and only 6% of men were treated with bisphosphonates (Chi-square = 4.18, p < 0.05). There was also a statistically significant difference in overall treatment including bisphosphonates and calcium/vitamin D between the sexes (Chi-square = 6.81, p < 0.05). Conclusion. This study shows that there is clearly a need for improvement in secondary prevention of fragility fractures in both sexes, but men are significantly less likely to be investigated and treated than women. It is important to include recommendations for men in future guidelines and increase the awareness of male osteoporosis. This is of particular importance as men have a higher morbidity and mortality following hip fractures than women. Orthopaedic surgeons should therefore take on responsibility for these fracture patients and ensure that the process of secondary prevention is initiated

BACKGROUND CONTEXT. Osteoporosis causes decreased bone mineral density, which predisposes to fragility fractures. Low-energy vertebral compression fractures are the most common type of osteoporotic fragility fracture. Prior studies have shown that only one-quarter of patients diagnosed with an osteoporotic fracture are referred or treated for osteoporosis. PURPOSE. To identify the rate of recurrent fractures after vertebroplasty and after the conservative treatment for patients aged 50 years and older who sustained low impact vertebral compressions fractures over a 6-month period. STUDY DESIGNED/SETTING. Prospective study. PATIENT SAMPLE. The sample included patients 50 years or older who had a low-energy vertebral compression fracture. The patients were divided into two groups: first group (n=24) - patients teated by vertebroplasty and the second group (n=34) - patients treated conservatory. There was no significant difference among the groups in terms of the vertebral levels or BMD. METHODS. Patients records were reviewed for fracture recurrence and in the same time we examined medical records for osteoporotic medication prescriptions, refferals to endocrinology and to dual-energy X-ray absorptiometry (DEXA) scans. RESULTS. Confounding factors of age at the procedure, sex and chronic steroids use were considered and found to have no statistically significant difference between the two groups and between those with fracture recurrence and those without fracture recurrence. Four vertebroplasty procedure resulted in a recurrent fracture within the first 6 months. In the patient group treated conservatory 8 patients sustained recurrent fractures. Patients with recurrent vertebral fracture didn't receive active osteoporosis treatment. Within 6 months after the fracture only 21% of patients were receiving active osteoporosis treatment. CONCLUSIONS. The incidence of recurrent fracture after vertebroplasty or after conservative treatment is substantial but have no statistically significant difference between the two groups. We consider that the recurrence rate is not related with the surgical intervention but is the result of natural history of the patient's osteoporosis because the patients do not understand the importance of initiating active therapeutic intervention for osteoporosis recommended by physicians

Fracture repair occurs by two broad mechanisms: direct healing, and indirect healing with callus formation. The effects of bisphosphonates on fracture repair have been assessed only in models of indirect fracture healing. A rodent model of rigid compression plate fixation of a standardised tibial osteotomy was used. Ten skeletally mature Sprague–Dawley rats received daily subcutaneous injections of 1 µg/kg ibandronate (IBAN) and ten control rats received saline (control). Three weeks later a tibial osteotomy was rigidly fixed with compression plating. Six weeks later the animals were killed. Fracture repair was assessed with mechanical testing, radiographs and histology. The mean stress at failure in a four-point bending test was significantly lower in the IBAN group compared with controls (8.69 Nmm. -2. (. sd. 7.63) vs 24.65 Nmm. -2. (. sd. 6.15); p = 0.017). On contact radiographs of the extricated tibiae the mean bone density assessment at the osteotomy site was lower in the IBAN group than in controls (3.7 mmAl (. sd. 0.75) vs 4.6 mmAl (. sd. 0.57); p = 0.01). In addition, histological analysis revealed progression to fracture union in the controls but impaired fracture healing in the IBAN group, with predominantly cartilage-like and undifferentiated mesenchymal tissue (p = 0.007). . Bisphosphonate treatment in a therapeutic dose, as used for risk reduction in fragility fractures, had an inhibitory effect on direct fracture healing. We propose that bisphosphonate therapy not be commenced until after the fracture has united if the fracture has been rigidly fixed and is undergoing direct osteonal healing.

We matched 78 patients with a loose cemented Charnley Elite Plus total hip replacement (THR) by age, gender, race, prosthesis and time from surgery with 49 patients with a well-fixed stable hip replacement, to determine if poor bone quality predisposes to loosening. Clinical, radiological, biomechanical and bone mineral density indicators of bone quality were assessed. Patients with loose replacements had more pain, were more likely to have presented with atrophic arthritis and to have a history of fragility fracture, narrower femoral cortices and lower peri-prosthetic or lumbar spine bone mineral density (all t-test, p < 0.01). They also tended to be smokers (chi-squared test, p = 0.08). Vitamin-D deficiency was common, but not significantly different between the two groups (t-test, p = 0.31). In this series of cemented hip replacements performed between 1994 and 1998, aseptic loosening was associated with poor bone quality. Patients with a THR should be screened for osteoporosis and have regular radiological surveillance

Fracture is the only clinically relevant aspect of osteoporosis—a major public health problem in many countries. The strongest predictor for a new fragility fracture is a previous one. For instance, a patient with one osteoporotic vertebral compression fracture has about a seven-fold increased hip fracture risk; a patient with two compression fractures a 14-fold hip fracture risk. Today, we have evidence based and efficient osteoporosis drugs as well as non-pharmacologic methods for fracture prophylaxis. In risk group patients it often is possible to halve the fracture risk. The orthopaedic surgeon is the first and sometimes the only doctor a fracture patien sees. Therefore, as orthopaedic surgeons, we have a great opportunity—and indeed an onus—to identify patients with increased fracture risk, and to do something about it. Imagine patients with myocardial infarction or stroke discharged from hospital without blood pressure control or having a biochemical profile taken? Such negligence is, alas, not uncommon for patients with fragility fractures. We must think in terms of absolute fracture risk, and implement today’s evidence based knowledge. Secondary prophylaxis should be an integrated part in fracture treatment. And this calls for a multidisciplinary and multiprofessional teamwork including surgeons, geriatricians, endocrinologists and general practitioners, as well as nurses, physiotherapists and a wide range of other paramedical specialists. Such “fracture chains” will reduce the number of unnecessary and preventable injuries and will have a great impact in terms of cost and suffering. This symposium will give an overveiw of fracture-preventing strategies

Introduction: Distal Radius Fractures (DRF) and Hip Fractures are considered as fragility fractures. The purpose of this study was to assess whether DRF precedes hip fracture or not. This retrospective analysis was carried out in a group of patients who sustained bilateral non contemporary hip fractures. Materials and Methods: Retrospective analysis of radiographs and notes of all the patients requiring surgery for bilateral neck of femur fractures, from January 1994 to June 2005 at a district general hospital. Data included ages at the first and second fractures, mechanisms of injury, types of fracture and implants used. Time interval between the two fractures was also noted. These were analyzed for presence of any Distal Radius Fractures (DRF) prior to first admission for hip fracture and time period between first and second admission. It was also analyzed whether a DRF was sustained between these two episodes. Results: Ninety five patients had bilateral neck of femur fractures during the study period with an average age of 76 years at the first fracture. There were eighty-three females and twelve males. The time interval between bilateral non contemporary hip fracture was 2.5 years. Out of these ninety five patients a small minority of patients had a DRF preceding their first hip fracture. Those sustaining DRF prior to their second hip fracture was also studied and statistical methods were employed to predict the presence of DRF prior to hip fractures. Conclusion: This study shows that there is no correlation between sustaining two fragility fractures i.e DRF & Hip Fracture and DRF may not necessarily precede a Hip Fracture

Aims. Surgical treatment of hip fracture is challenging; the bone is porotic and fixation failure can be catastrophic. Novel implants are available which may yield superior clinical outcomes. This study compared the clinical effectiveness of the novel X-Bolt Hip System (XHS) with the sliding hip screw (SHS) for the treatment of fragility hip fractures. Methods. We conducted a multicentre, superiority, randomized controlled trial. Patients aged 60 years and older with a trochanteric hip fracture were recruited in ten acute UK NHS hospitals. Participants were randomly allocated to fixation of their fracture with XHS or SHS. A total of 1,128 participants were randomized with 564 participants allocated to each group. Participants and outcome assessors were blind to treatment allocation. The primary outcome was the EuroQol five-dimension five-level health status (EQ-5D-5L) utility at four months. The minimum clinically important difference in utility was pre-specified at 0.075. Secondary outcomes were EQ-5D-5L utility at 12 months, mortality, residential status, mobility, revision surgery, and radiological measures. Results. Overall, 437 and 443 participants were analyzed in the primary intention-to-treat analysis in XHS and SHS treatment groups respectively. There was a mean difference of 0.029 in adjusted utility index in favour of XHS with no evidence of a difference between treatment groups (95% confidence interval -0.013 to 0.070; p = 0.175). There was no evidence of any differences between treatment groups in any of the secondary outcomes. The pattern and overall risk of adverse events associated with both treatments was similar. Conclusion. Any difference in four-month health-related quality of life between the XHS and SHS is small and not clinically important. There was no evidence of a difference in the safety profile of the two treatments; both were associated with lower risks of revision surgery than previously reported.

Aim: to determine the proportion of patients with fragility fractures who underwent risk assessment for osteoporosis as a result of their fracture clinic attendance prior to and following reinforcement of guidelines. Methods: The inclusion criteria were defined as: new patients fifty years of age or over sustaining a fragility fracture of their distal radius presenting during two three month periods in 2004 (April to June and October to December). Guidelines for osteoporosis risk assessment (the Northumberland guidelines) were reinforced during the interim period. Patients were identified from hospital records and the notes obtained to confirm the fracture type as fragility. The number assessed during each period was determined from outpatient referral for DEXA records and compared. Patients who had undergone DEXA scanning in the year prior to their fracture clinic attendance were excluded from the analysis. Results: from April to June there were forty-six patients (39 women and 7 men) with a mean age of 73 years while between October and December there were fifty-four patients (48 women and 6 men) with an average age of 68 years. In the April to June cohort 3 patients had already had a DEXA scan prior to fracture clinic attendance. Of the 43 remaining patients 3 were risk assessed for osteoporosis (7%). Within the October to December group two patients had previously undergone DEXA scanning and of the remaining 52 patients 16 (31%) underwent osteoporosis risk assessment. Conclusion: Risk assessment for osteoporosis is still carried out ineffectively by orthopaedic surgeons even following enforcement of guidelines

Purpose. In 2010, the new clinical guideline of Osteoporosis Canada for the diagnosis of osteoporosis, clearly indicates that patients with high-risk of fracture are those that have already sustained a fracture (osteoporotic fracture). Until now, only 12% of the 3,400 fractures that we treat each year receive a treatment for osteoporosis. We are validating an evaluation protocol and a multidisciplinary systematic follow-up approach for osteoporosis. Patients are managed by a clinical nurse specialist. We are recruiting 543 patients with an osteoporotic fracture at Hal du Sacré-Coeur de Montréal. We aim to evaluate: 1) the incidence of a second osteoporotic fracture, 2) the initiation of a treatment and determine the compliance and adherence to treatment and 3) the evaluation of CTX-1 and Osteocalcin at Baseline, 6, 12,18 et 24 months (treatment efficacy) and 4) the functional outcome and quality of life post-fracture. Method. We've enrolled 153 subjects (men and women) over 40 years of age who were treated for an osteoporotic fracture at the orthopaedic clinic of Hal du Sacré-Coeur de Montréal. After starting a treatment protocol for osteoporosis, the subjects will be followed for a 24 months period at different time intervals. During these visits, they fill up functional outcome questionnaires, undergo physical exam, blood test, x rays and their compliance to treatment is evaluated. Results. Mean patients age was 65 y.o (+ 13). Two hundred seventeen patients were approached and 153 patients were enrolled (23 men and 130 women). Eleven patients refused to be part of the systematic follow up because they were satisfied with their family doctors osteoporosis management. Fifty-three were explained treatment and follow up and refused to participate. Thirteen patients (9%) dropped out after six months. One patient died. Twenty-one patients (13.7%) were already on bisphosphonates and 53 pts (34.6 %) had already sustained a fragility fracture. All patients were prescribed risedronate except three that were prescribed zoledronic acid or pamidronate for intolerance or contraindication to oral bisphosphonates. Up to now, we obtained 71% adherence and 91% persistence. After validation, 10% of the patients needed to be referred to a rheumatologist and 90% of the patients were managed by the clinical nurse specialist. Conclusion. Our multidisciplinary systematic follow up of osteoporotic fracture improved the osteoporosis treatment rate from 12 to 71 % in our orthopaedic surgery department. Clinical Nurse Specialists could represent the best approach to manage the underlying osteoporosis that leads to fragility fractures

Highly active anti-retroviral therapy has transformed HIV into a chronic disease with a long-term asymptomatic phase. As a result, emphasis is shifting to other effects of the virus, aside from immunosuppression and mortality. We have reviewed the current evidence for an association between HIV infection and poor fracture healing. The increased prevalence of osteoporosis and fragility fractures in HIV patients is well recognised. The suggestion that this may be purely as a result of highly active anti-retroviral therapy has been largely rejected. Apart from directly impeding cellular function in bone remodelling, HIV infection is known to cause derangement in the levels of those cytokines involved in fracture healing (particularly tumour necrosis factor-α) and appears to impair the blood supply of bone. Many other factors complicate this issue, including a reduced body mass index, suboptimal nutrition, the effects of anti-retroviral drugs and the avoidance of operative intervention because of high rates of wound infection. However, there are sound molecular and biochemical hypotheses for a direct relationship between HIV infection and impaired fracture healing, and the rewards for further knowledge in this area are extensive in terms of optimised fracture management, reduced patient morbidity and educated resource allocation. Further investigation in this area is overdue

The international literature base demonstrates that individuals living with diabetes mellitus (DM) are at increased risk of mortality and post-operative complications following hip fracture surgery (HFS) than non-diabetics. Studies investigating databases in American, European or Asiatic populations highlight the impact geography can have on the resultant investigation. We aim to quantify the impact DM has on HFS patients in a single university hospital. The HIPE dataset of fragility fractures occurring in Galway University Hospital from 2014–2016 were analysed and cross referenced with hospital laboratory and public databases. A database of 759 individuals was created including 515 females and 237 males, with a mean age of 78+/−12.2 years, of which 110 patients had DM. The patient length-of-stay (PLOS) was comparable in all groups with patient age being the primary influencing factor. An extended PLOS correlated with an increased long-term mortality. A trend toward increased occurrence of sub-trochanteric fractures was observed in diabetics with fewer periprosthetic and intertrochanteric fractures. Patients with DM had a significant increased risk of post-operative mortality compared to non-diabetics. Males with DM where at a greater risk of death after HFS [HR 2.29, 95% CI 1.26–4.17. p=0.006] than females with DM [HR 1.69, 95% CI 0.99–2.91. p=0.056]. The presence of DM did not directly impact a patient's PLOS or increase the need for a re-operation. DM is associated with increased post-operative patient mortality and may influence the anatomical fracture pattern. This observation will support further investigation into the mechanical and biochemical changes occurring in the femur in individuals living with DM

Tibial plateau fractures classically present in a bimodal distribution associated with high energy mechanisms in the younger population and fragility fractures in the elderly populations as a result they are well suited for looking at the effect major trauma centre status. Military trauma surgeons in training should be exposed to as much young high-energy trauma as possible to equip them for operations. Retrospective review of all tibial plateaus presenting to RVI 20 months before MTC status and 20 months following this. 61 patients pre, 66 post. Schatzker grade 1–4 were similar pre and post change. Post change there was an increase in Schatzker 5 (62%) and 6 (27%). High energy injuries were most common in younger males, cause was falls followed by RTAs. MTC status has meant an increase in high energy tibial plateaus (Schatzker 5–6) These were predominantly seen in younger males with high-energy mechanisms. As this is likely to be replicated across all injuries, we would recommend military trauma surgeons have a significant period of time training in major trauma centres to ensure adequate exposure to young high energy trauma

Introduction: Osteoporotic fracture care is on the increase in healthcare systems worldwide. In the UK the British Orthopaedic Association (BOA) recommends all patients > 60 presenting with fragility fracture (FF) should be evaluated for osteoporosis by axial Dual Energy X-ray Absortiometry (DEXA) scan. All patients < 60 should be assessed for osteoporosis risk factors and DEXA scanned if present. The National Institute for Clinical Excellence (NICE) recommends all woman > 75 with FF should be prescribed secondary prevention bisphosphonates for osteoporosis 1st line without the need for DEXA scan. Aim: To evaluate how often patients with FF were appropriately managed in fracture clinic using BOA and NICE guidelines for the secondary prevention of FF. Methods: and Results: Over a two month period 18 of 184 new patients admitted to fracture clinic were identified as having FF (16 females, 2 males with age ranges 61–89). They were followed up over six months. According to BOA and NICE guidelines only 33% (6 of 18 patients) and 42% (3 of 7 > 75’s) respectively were appropriately managed for secondary prevention. Following this a FF prevention strategy was implemented. This consisted of fracture clinic infrastructure changes, a staff awareness teaching programme and the assignment of an osteoporosis nurse specialist. A re-audit six months later identified 16 of 175 new patients as having FF. According to BOA and NICE guidelines 88% (14 of 16 patients) and 75% (6 of 8 > 75’s) respectively were appropriately managed for secondary prevention. Fisher’s Exact Test showed a significant improvement in secondary prevention management according to BOA guidelines (p< 0.05), but not NICE guidelines (p=0.2), as a consequence of these interventions. Conclusion: Osteoporosis is an important cause of fracture in elderly patients. Changes to fracture clinic infrastructure, educational teaching initiatives and osteoporotic nurse specialists can improve uptake of secondary prevention measures in fracture clinic aimed at reducing risk of future fragility fractures in elderly patients

Current evidence suggests that in Australia more than 80% of individuals are not receiving treatment for osteoporosis following an initial osteoporotic fracture. The earliest opportunity to identify many individuals with osteoporosis is following their first osteoporotic fracture, which is usually less severe than subsequent fractures. As these fractures are usually treated by orthopaedic surgeons it was decided to survey Australian orthopaedic surgeons to determine their understanding, attitudes and involvement in the management of osteoporosis. Methods: The AOA in conjunction with the BJD distributed a questionnaire to 945 members. The results of 449 (48%) returned questionnaires were collated and sent to the Swedish National Competence Centre for Musculo-skeletal Disorders for analysis. Results: Responding surgeons claimed to treat at least 24,000 osteoporotic fractures per year. Sixty per cent felt they had ‘none’ or ‘insufficient’ training in osteoporosis and considered they had ‘no’ or only ‘slight knowledge’ in managing the condition. Approximately 65% of surgeons either ‘never’ or only ‘sometimes’ initiated investigation or treatment of patients with osteoporotic fractures; only 11% ‘always’ or ‘very often’ initiated investigation or treatment. If an osteoporotic fracture is suspected most (70%) refer to a GP or osteoporosis specialist, with only 22% evaluating the condition themselves. Although 46% claimed that they referred patients for a BMD study always or most of the time, only 14% did so routinely. Fifty percent felt it was the GP’s responsibility to identify and initiate the evaluation of the underlying osteoporosis of patients with fragility fractures, compared with 29% who considered that this was the orthopaedic surgeon’s responsibility. Eighty five per cent of the respondents do not prescribe any pharmacological treatment for osteoporosis management. Most commonly (36%) there was a preference for surgery rather than drug prescription. Twenty four percent had access to a specific osteoporosis team for treating osteoporosis. No experience with treating osteoporosis (23%) and no formal education in osteoporosis (16%) were other common reasons. Very few orthopaedic surgeons felt it was their responsibility to treat osteoporosis, however 52% were interested in attending a course on osteoporosis. The findings are contrasted with those of an international study conducted by the Bone and Joint Decade and the International Osteoporosis Foundation, using the same questionnaire. Conclusions: The evidence of under- treatment of osteoporosis after first fragility fractures, suggests that it may be necessary for orthopaedic surgeons to re-evaluate their approach to the management of osteoporosis, either by themselves or others. Further educational opportunities in this area should be considered

We performed a retrospective review of all patients admitted to two large University Hospitals in the United Kingdom over a 24-month period from January 2008 to January 2010 to identify the incidence of atypical subtrochanteric and femoral shaft fractures and their relationship to bisphosphonate treatment. Of the 3515 patients with a fracture of the proximal femur, 156 fractures were in the subtrochanteric region. There were 251 femoral shaft fractures. The atypical fracture pattern was seen in 27 patients (7%) with 29 femoral shaft or subtrochanteric fractures. A total of 22 patients with 24 atypical fractures were receiving bisphosphonate treatment at the time of fracture. Prodromal pain was present in nine patients (11 fractures); 11 (50%) of the patients on bisphosphonates suffered 12 spontaneous fractures, and healing of these fractures was delayed in a number of patients. This large dual-centre review has established the incidence of atypical femoral fractures at 7% of the study population, 81% of whom had been on bisphosphonate treatment for a mean of 4.6 years (0.04 to 12.1). This study does not advocate any change in the use of bisphosphonates to prevent fragility fractures but attempts to raise awareness of this possible problem so symptomatic patients will be appropriately investigated. However, more work is required to identify the true extent of this new and possibly increasing problem

The global COVID-19 pandemic has resulted in 71 million confirmed global cases and 1.6 million deaths. Hip fractures are a major global health burden with 70 000 admissions per annum in the UK. This multicentre UK study aimed to assess the impact of perioperative COVID-19 status on 30-day and 120-day mortality after a hip fracture. A prospective multicentre study of 10 hospitals in South England comprising eight DGHs and two MTCs treating c.8% of the annual incidence of hip fractures in England was performed. All fragility hip fractures presenting between 1. st. March to 30. th. April 2020 were eligible for inclusion. COVID-19 infection was diagnosed after a positive PCR swab. Expected 30-day mortality was calculated using the Nottingham Hip Fracture Score (NHFS), with non COVID-19 30-day mortality compared against the same study period in 2019. 746 patients were included in this study with 87 (12%) testing positive for COVID-19. Crude 30-day mortality for COVID-19 positive hip fractures was 35% compared to 6% for COVID-19 negative patients, with COVID-19 positive 30-mortality rates being significantly higher than expected based on NHFS alone (RR 3.0, 95% CI 1.57–5.75, p<0.001). There was no significant difference between expected NHFS and actual 2019 and COVID-19 negative hip fracture rates (p>0.05). Overall 120-day mortality was significantly higher for COVID-19 positive (46%) compared to COVID-19 negative (15%) hip fractures (p<0.001). However, mortality rates from 31–120 days were not significantly different despite COVID-19 status (p=0.107). COVID-19 results in significant increases in both 30 and 120-day mortality, above the expected mortality rates when confounding comorbidities are accounted for by the NHFS. However, COVID-19 positive patients who survive beyond 30-days have comparable mortality rates up to 120-days when compared to COVID-19 negative patients. Efforts should therefore be made to mitigate known risks for 30-day mortality such as time to theatre, to improve 30-day mortality rates in COVID-19 positive patients thus increasing the likelihood of long-term survival

Purpose: To test a novel Patient Education and Physician Alerting (PEPA) intervention that seeks to improve the proportion of correct diagnosis and management of osteoporosis in older adults who have sustained a recent hip fracture secondary to a fall. Methods: Design: Six-month randomized controlled trial. Participants were randomized either to the PEPA group (intervention) or the usual-care group (control). Participants and Setting: Forty-eight men and women aged 60 years and older who were admitted to Vancouver General Hospital for a fall-related hip fracture.|Measurements: The Diagnosis and Management Questionnaire (DMQ) was administered to all participants to determine the rate of investigation and treatment of osteoporosis. The responses were validated in part by physician report obtained for one half of the participants. Statistical Analyses: We compared the difference between the two experimental groups in the proportion of individuals who received bisphosphonate therapy within 6 months after their hip fracture using the chi-square test. The alpha level was set at P < 0.05. |. Results: To date, thirty-three of the 48 participants have completed this 6-month randomized controlled trial. Among these 33 participants, we found a significant difference between the two groups in the proportion of individuals who received bisphosphonate therapy after their hip fracture (p < 0.001). In the PEPA group, 70% (14 out of 20) were put on bisphosphonate therapy within 6 months after experiencing a fragility hip fracture. In contrast, 0% (0 out of 13) were put on bisphos-phonate therapy within 6 months after experiencing a fragility hip fracture in the usual-care group. Of the 78 individuals who were eligible for this study, 48 agreed to participate. Conclusions: Currently, there is an established care gap for patients who sustain a fragility fracture. This cohort of individuals who fractured their hip did not receive guideline care unless recommended by the PEPA intervention letters sent to the participant delivered to the family physician. Patients who sustain a low-trauma hip fracture and are “at risk” for osteoporosis and do not receive recommended “best practice” care. Funding: Commerical funding.

Introduction: Bone mineral density (BMD) is currently the gold standard in predicting osteoporotic fracture, but evidence suggests that over one third of such fractures occur in those with osteopenia or even normal BMD. The level of bone turnover may affect bone quality in these patients independently of BMD. Bone markers have evolved as tools in monitoring anti-resorptive treatment in osteoporosis. Aims: The aim of this study was to investigate if levels of bone markers in postmenopausal women could be used as an adjunct to BMD measurements in the assessment of fragility fracture risk. Patients and Methods: 60 postmenopausal women (30 osteoporotic, 30 with normal BDM) were studied. A single BMD measurement by dual energy x-ray absorptiometry (DEXA) enabled categorisation. Serum bone formation markers (bone specific alkaline phosphatase (BSAP) and osteocalcin (OC)), and resorption marker (C-telopetide of type 1 collagen (CTX)), were measured. History of low trauma fracture was documented for each woman. Results: 36% of the osteoporotic group had experienced at least one fragility fracture. However, the femoral neck and combined spinal BMD in these women was not significantly different from the 64% of osteoporotic women who had no prior fracture. There was also no significant difference in the age of women in both subgroups. Serum bone markers were significantly increased in the osteoporotic fracture subgroup when compared to the non-fracture subgroup and also to the non-osteoporotic controls. The largest increases were seen in the levels of CTX. Smaller increases in all markers were seen when the non-fracture subgroup was compared to the non-osteoporotic control group but these increases did not reach statistical significance. Conclusions: Bone turnover is significantly increased in postmenopausal osteoporotic women with previous fracture compared to both osteoporotic non-fracture counterparts and non-osteoporotic controls. This suggests higher bone turnover will increase fracture risk in osteoporotic women. It is possible that combining 2 or 3 markers to produce an “index of bone turnover” would be a useful tool when used in addition to BMD to identify those at greatest fracture risk

Background and objective: in 2003 in its publication ‘Care of fragility fracture patients’ The British Orthopaedic Association highlighted the orthopaedic surgeon’s role in assessment and management of patients at high risk from osteoporosis. In general such secondary prevention of osteoporosis is carried out poorly by orthopaedic surgeons. This audit aimed to determine if software which identifies patients at high risk from osteoporosis from clinic letters, improves orthopaedic surgeons’ referral rates for DEXA. Methods: two audit cycles were carried out using local guidelines. The audits concerned patients over 50 years having sustained a fragility fracture of the distal radius. According to local guidelines all such patients should undergo DEXA. Patients were identified from hospital records and the number referred for DEXA determined. Those who had undergone DEXA in the year prior to fracture were excluded. The baseline audit was from April to June 2004 inclusive followed by closure of the loop between October and December 2004 following reinforcement of guidelines. Following continued poor referral rates at this point the software programme was introduced. It identifies patient age and key words in dictated clinic letters when they are being printed, for example distal radial fracture. Appropriate patients have computer generated osteoporosis advice included at the bottom of the general practitioner letter along with a DEXA referral form which General Practitioners complete. A further audit using similar methods was carried out 3 months after the software introduction (January 2006). Results: baseline audit identified forty-three patients (36 women and 7 men) with a mean age of 73 years, 3 were referred for DEXA (7%). Following reinforcement of guidelines fifty-two patients were identified (46 women and 6 men) with a mean age of 68 years, 16 (31%) were referred. At re-audit (following the introduction of the software programme) 45 patients were identified (38 women and 7 men) with an average age of 71 years. 30 (67%) were referred for DEXA. This is a significant improvement using a Chi squared analysis. Conclusion: the software programme significantly improves orthopaedic surgeon identification of patients at high risk of osteoporosis and referral rates for DEXA

Purpose: We report the prevalence of vitamin D deficiency and other causes of secondary osteoporosis in a group of typical and atypical fragility fracture patients. Method: A chart audit of 399 patients (117 males, mean age 64.6, SD 12.8; 282 females, mean age 63.5, SD 14.6) referred from an inner city orthopaedic unit to the Metabolic Bone Disease Clinic (MBDC) over a three-year period was conducted. Fracture locations and etiology: 90 hip (76 fragility), 161 wrist (135 fragility), 8 vertebral (6 fragility), 77 shoulder (62 fragility), 62 other sites (45 fragility), 1 both hip and shoulder (fragility). Results: Thirty percent of patients (42 males, 78 females) had a total of 149 secondary causes of OP recorded. Secondary causes included medication use (oral steroids, anti-convulsants); rheumatic, gastrointestinal and endocrine conditions (RA, IBD, Graves disease, Type I DM, hyperparathyroidism); hypogonadal states (premature ovarian failure, hypogonadism); genetic conditions (hypophosphatasia); hematological conditions (thalassemia); miscellaneous causes (smoking, renal impairment). A total of 308 patients completed blood work, including 269 patients who had a 25-OH vitamin D measurement: 7 patients were deficient at ≤ 25 nmol/l, 137 were insufficient at 26 to 74 nmol/l, and 125 were sufficient at ≥ 75nmol/l. There were no differences between males and females (p = 0.457), or among fracture locations (p 0.246). Over 75% of blood/urine analyses were within the normal range for: 1,25 vitamin D, ALP, ALT, AST, bilirubin, creatinine, T3, T4, homocysteine, magnesium, phosphorus, platelets, serum calcium, protein, albumin, globulin, TSH, tissue transglutaminase, Vit B12, WBC, 24 hour urine calcium and phosphorus. Between 50 and 74% of the blood/urine analyses were within the normal range for: CRP (n = 30; 30% elevated), ESR (n = 173; 43% elevated), testosterone (n = 53; 25% of men below normal), bioavailable testosterone (n = 52; 40% of men below normal), N- telopeptide (n = 5; 30% of women elevated), RBC folate (n = 12; 33% elevated), 24 hour urine creatinine (n = 51; 27% below normal). Conclusion: Half of the fracture patients were vitamin D insufficient. A standardized blood test protocol for all fragility fracture patients is in use

Introduction: With a worldwide aging population, and an expected doubling in numbers of people older than 65 between 1990 and 2020, we are in the midst of a predicted increase in osteoporosis and resultant fractures. The International Osteoporosis Foundation recently surveyed consultant orthopaedic surgeons in mainland Europe and New Zealand to determine how patients with osteoporotic fractures were managed. Their conclusion was that treatment patterns were varied, and the findings supported the need to improve fragility fracture services to reduce the risk of recurrent fractures. Aim: The aim of our study was to see how Irish practices and opinions related to the IOF survey, in anticipation of a formal protocol being established in our unit. Methods: A modification of the International Osteoporosis Foundation survey used in 2002 was sent to 85 Consultant Orthopaedic Surgeons listed in the Irish Medical Directory. The questionnaire evaluated the surgeon’s education and knowledge of osteoporosis management, as well as estimated numbers of patients being treated with osteoporosis and the investigations available to their service. Treatment and referral patterns were also established. All responses were anonymous. Results: The Irish response rate to the survey of nearly 50% was higher than that of our European colleagues, and showed that only 25% of surgeons felt they received sufficient training in the area of osteoporosis, but only a minority were not confident managing the disease. One-quarter of those surveyed would treat a patient with a fragility fracture for osteoporosis themselves, while over half would refer the patient on to a General Practitioner for further management. 50% of Irish Consultants would first order bone mineral densitometry, and nearly three-quarters believe the General Practitioner is the most appropriate professional to follow up these patients. Significantly, 15% of Orthopaedic surgeons did not have any access to densitometry. The most popular treatment modality is a combination of calcium and vitamin D supplementation in conjunction with Alendronate. Conclusion: There is currently a lack of standarisation in the management and follow up of patients with osteoporosis. While the disease and its treatment is an internationally important topical issue, our study showed that at a national level there is a lack of consistency between the need for specialised services and implementation of treatment algorithms, due in part to lack of investigative facilities and organised management teams

Introduction: Traumatic vertebral compression fractures (VCF) should be distinguished from fragility fractures, occurring as a result of decreased bone strength due to osteoporosis or cancer. Polymethylmethacrylate cement (PMMA), as standard in fragility fractures, does not have the capacity to undergo remodeling. Therefore in young patients, a bio-compatible/–resorbable alternative would be preferable. KyphOs FS(R), a calcium magnesium hydroxyapatite cement has been developed for use during Balloon Kyphoplasty (BKP), a minimal invasive therapy. This single-arm multicenter study evaluates the safety and effectiveness of this cement during BKP in young patients with stable VCFs. We describe the clinical results up to 3mo of the ongoing 1-year follow-up study. Methods: Male and female patients, aged 50 years or less, with up to 3 VCFs of type A1.1, A1.2 or A3.1, according to the Magerl/AO classification were included. The primary endpoint was the change from baseline in the 24 point Roland Morris Disability Questionnaire (RMDQ) score at seven days. Secondary endpoints included the quality of life as measured by EuroQol-5 Domain questionnaire (EQ-5D), the 10 point self-rated back pain (VAS) and device and/or procedure related adverse events. Based on the standard deviation in the Wood study, up to 100 patients had to be enrolled to detect the minimal clinical important difference (MCID) of 2–3 pts on the primary endpoint. Results: 50 patients out of 51 enrolled were eligible. The mean age was 36.4 years, 64% were male. 80% of the patients were treated for 1 VCF, 14% for 2 VCFs and 6% for 3 VCFs. At 3 mo, data of 45 patients were available. Mean RMDQ score at baseline was 20.29pts. The change from baseline in RMDQ at 7d was 9.42pts(95%CI 7.50–11.34, p< 0.0001) and 16.76pts(95%CI 15.21–18.30,p< 0.0001) at 3mo. Mean EQ-5D score at baseline was 0.16pts. The change from baseline in total EQ-5D at 7d was 0.52pts(95%CI 0.42–0.62,p< 0.0001) and 0.71pts(95%CI: 0.60–0.82,p< 0.0001) at 3mo. The change from baseline in VAS at 7d was 4.44pts(95%CI 3.80–5.08,p< 0.0001) and 5.43pts(95%CI 4.81–6.05,p< 0.0001) at 3mo. There were no device-related serious adverse events during the peri-operative period up to 3 mo. Discussion: The MCID on the RMDQ is 2–3pts. In this study we obtained a difference of 9.42 points at 7 days. The recruitment was terminated earlier because of the highly significant results. The results on RMDQ were confirmed on all the other secondary endpoints with further improvement up to 3 mo. Conclusion: The use of KyphOs FS(R) during BKP, appears to be a safe and effective method to treat traumatic VCFs in young patients. Longer follow-up is needed to confirm the results at 1 year

Abstract. Objectives. Our objective was to determine the incidence of post-operative COVID-19 infection within the first two weeks following treatment at the COVID-free site. During the COVID-19 pandemic our hospital saw one of the highest rates of COVID-19 infection in the United Kingdom. As a result, our trauma services were relocated to a vacant private elective hospital to provide a ‘COVID-free’ setting for trauma patients. Patients admitted to the COVID-free site were screened for coronavirus infection and only treated at that site if asymptomatic. Those with symptoms were treated at the ‘COVID’ site. Method. We collected data at the COVID-free site during the first seven weeks of its’ establishment. Inclusion criteria were all patients presenting for operative management of limb trauma; however, fragility hip fractures were excluded. All patients were screened for symptoms of COVID-19 infection at their 2-week follow-up appointment. Results. 72 patients presented to our service during the study period. The mean age was 34.9 years (21 to 89). 62 patients had general anaesthesia (86%), 7 patients had regional anaesthesia (10%) and 3 patients had local anaesthesia (4%). One asymptotic patient who was swabbed for COVID-19 on admission returned a positive result. This patient had contracted the infection before surgery and was excluded from further analysis. 71 patients (100%) remained asymptomatic at follow-up and none had required medical attention for suspected COVID-19 infection. Conclusion. A ‘COVID-free’ trauma service was established in a private elective hospital during the pandemic. None of the patients undergoing urgent trauma surgery in this setting developed COVID-19 symptoms as a result of their hospital admission. Establishing a separate site with screening to avoid admission of patients with COVID-19 infection can allow safe emergency surgery. This data can support informed consent and reassure patients of their risks when we resume day case and elective surgery. Declaration of Interest.

Aims

Frailty greatly increases the risk of adverse outcome of trauma in older people. Frailty detection tools appear to be unsuitable for use in traumatically injured older patients. We therefore aimed to develop a method for detecting frailty in older people sustaining trauma using routinely collected clinical data.

Aims

Femoral periprosthetic fractures are rising in incidence. Their management is complex and carries a high associated mortality. Unlike native hip fractures, there are no guidelines advising on time to theatre in this group. We aim to determine whether delaying surgical intervention influences morbidity or mortality in femoral periprosthetic fractures.

Background. Reduced bone mineral density is recognised as a risk factor for hip fractures and fragility fractures in general. Vitamin D is important in maintaining healthy bone mineral levels and can therefore affect risk of hip fracture. We investigated the correlation between vitamin D levels and bone mineral density, as well as fracture type, in neck of femur fractures and also assessed the relationship of vitamin D and social deprivation. Method. We included all patients admitted to our department, with a neck of femur fracture over one year (October 2013 to October 2014). We analysed vitamin D levels for all patients during admission and compared these to bone mineral density scores, based on DEXA scan results; hip fracture type & comminution, based on admission radiographs; and levels of social deprivation, based on the patient's address. Results. In total 360 patients were admitted over the study period, with a neck of femur fracture, of which 298 had vitamin D assessed and 76 had DEXA scans. Of these cohorts, 71% were found to be vitamin D deficient and 7% had osteoporosis. No significant correlation was found between vitamin D scores and bone density, or with level of vitamin D deficiency and fracture type or comminution. A significant correlation was however identified, between low vitamin D levels and decreasing levels of social deprivation (R=0.11, p=0.04). Conclusion. No relationship was identified between vitamin D levels and hip fracture type, suggesting that vitamin D cannot be used to predict patients at risk of more comminuted fractures. Although no relationship was also identified for bone mineral density and vitamin D, this may be because the sample size of DEXA scans was relatively small. Interestingly the relationship between vitamin D and social deprivation was the reverse of what was expected and suggests that affluent individuals may be at greater risk of low vitamin D

Aims. The aim of this study was to inform a definitive trial which could determine the clinical effectiveness of the X-Bolt Dynamic Hip Plating System compared with the sliding hip screw for patients with complex pertrochanteric fragility fractures of the femur. Patients and Methods. This was a single centre, participant blinded, randomised, standard-of-care controlled pilot trial. Patients aged 60 years and over with AO/ASIF A2 and A3 type femoral pertrochanteric fractures were eligible. Results. The primary outcome was the EuroQoL 5 Dimension Score (EQ-5D-3L) at one year following index fixation. A total of 100 participants were recruited, and primary outcome data were available for 88 patients following losses to follow-up and withdrawals. The mean difference in EQ-5D was 0.03 (95% confidence interval -0.17, 0.120; p = 0.720.) There were no significant differences in any of the secondary outcomes measures. The recruitment and follow-up rates from this feasibility study were as predicted. Conclusion. A definitive trial with 90% power to find a clinically important difference in EQ-5D would require 964 participants based upon the data from this study. We plan to start recruitment to this trial in Spring 2016. Take home message: A definitive trial of X-Bolt Dynamic Hip Plating System is feasible and should be conducted now in order to quantify the clinical effectiveness of this novel implant.
