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. The impact of concomitant injuries in patients with proximal femoral fractures has rarely been studied. To date, the few studies published have been mostly single-centre research focusing on the influence of upper limb fractures. A retrospective cohort analysis was, therefore, conducted to identify the impact and distribution of concomitant injuries in patients with proximal femoral fractures. Methods. A retrospective, multicentre registry-based study was undertaken. Between 1 January 2016 and 31 December 2019, data for 24,919 patients from 100 hospitals were collected in the Registry for Geriatric Trauma. This information was queried and patient groups with and without concomitant injury were compared using linear and logistic regression models. In addition, we analyzed the influence of the different types of additional injuries. Results. A total of 22,602 patients met the inclusion criteria. The overall prevalence of a concomitant injury was 8.2% with a predominance of female patients (8.7% vs 6.9%; p < 0.001). Most common were fractures of the ipsilateral upper limb. Concomitant injuries resulted in prolonged time-to-surgery (by 3.4 hours (95 confidence interval (CI) 2.14 to 4.69)) and extended length of stay in hospital by 2.2 days (95% CI 1.74 to 2.61). Mortality during the admission was significantly higher in the concomitant injury group (7.4% vs 5.3%; p < 0.001). Additionally, walking ability and quality of life were reduced in these patients at discharge. More patients were discharged to a nursing home instead of their own home compared to patients without additional injuries (25.8% vs 30.3%; p < 0.001). Conclusion. With a prevalence of 8.2%, the appearance of a concomitant injury is common in elderly patients with hip fracture. These patients are at a greater risk for death during the admission, longer hospital stays, and delayed surgery. This knowledge is clinically important for all who are involved in the treatment of proximal femur fractures. Cite this article: Bone Joint J 2021;103-B(9):1526–1533

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

Malnutrition is often associated with the advanced age and can be influenced by physical, mental, social and environmental changes. Hip fracture is a major issue and a prior poor nutritional status is associated with higher rates of perioperative complications and prolonged hospital length of stay. Prospective observational cohort study performed in a Level one trauma center including 189 consecutive patients admitted for hip fracture. The main outcome measure was the Mini Nutritional Assessment (MNA), a specific tool validated for geriatric population. This questionnaire was performed at admission by an independent assessor, at the same time as a large set of demographic and functional data. Blood samples were tested for blood count and albuminemia. Two groups were constituted and analysed according to a MNA score ≥ 24 (lower limit for normal nutritional status). Factors explored included physical and mental items. Impact of malnutrition was determined on hospital length of stay (HLS), discharge in an adverse location than prior to admission (DAL), complications and mortality rate. The rate of patients with malnutrition (or at risk) in this study is 47% (88 patients). Patients with a MNA < 24 are older (84.81 yrs ± 7.75 vs 80.41 ± 8.11, p<0,01), have more comorbidities (Charlson 2.8 ± 2.21 vs 1.67 ± 3.10, p<0,01), a more impaired mental (MMSE 19.39±8.55 vs 25.6±3.6, p<0,01) or physical status (MIF 105.3 ± 26.6 vs 121.8 ± 6.4, p< 0,01). Blood samples are not selective to detect malnutrition (p=0,64). Malnutrition is associated with a longer HLS (26.04±23.39 days vs 13.95±11.34 days, p<0,01), a greater DAL (58.9% vs 38.2%, p=0,02) and a higher one year mortality rate (23.9% vs 8.9 %, p<0,01). The prevalence of malnutrition in a geriatric population admitted for hip fracture is high. Blood samples at admission have clearly a poor value and a systematic screening with the MNA is mandatory. An early diagnosis will target specific interventions to reduce the physical and socio-economic impact of the malnutrition. Future studies should focus on actions in the perioperative stage (fast-track surgery, nutritional protocols, analgesia) and their impact on the socio-economic burden

Objectives. Aged trauma patients are at high risk for various comorbidities and loss of function following hip fracture. Consequently a multidisciplinary approach for the treatment of these patients has become more famous in order to maintain the patients” activity level and health status prior to trauma. This study evaluates the effect of a multidisciplinary inpatient rehabilitation on the short- and long-term functional status of geriatric patients following hip fracture surgery. Methods. A collective of 158 hip fracture patients (> 80 years) who underwent surgery were included in this study. An initial Barthel Index lower than 30 points was a criteria to exclude patients from this study. Two subgroups, depending on the availability of treatment spots at the rehabilitation center were made. No other item was used to discriminated between the groups. Group A (n=95) stayed an average of 21 days at an inpatient rehabilitation center specialized in geriatric patients. Group B (n=63) underwent the standard postoperative treatment. As main outcome parameter we used the Barthel Index, which was evaluated for every patient on the day of discharge and checkups after three, six and twelve months. Results. After three months, the average Barthel Index was 82,27 points for group A and 74,68 points for group B (p=0,015). In the six-months-checkup group A”s average Barthel Index was 84,05 points and group B”s was 74,76 points (p=0,004). After twelve months, patients from group A had an average Barthel Index of 81,05 while patients from group B had an average Barthel Index of 71,51 (p=0,010). Conclusion. This study reveals a significant better outcome in both, the short-term and the long-term functional status for geriatric hip-fracture patients, who underwent an inpatient treatment in a rehabilitation center following the initial surgical therapy. This is shown at the timepoints three, six and twelve month after discharge. To maintain quality of life and mobility as well as the patient”s independence in daily life, a treatment in a rehabilitation center specialized in geriatric patients is highly recommendable

Introduction: Fracture of the osteoporotic hip is more common in people over the age of 74. Purpose: To describe the co-operation between traumatologists and geriatric physicians in treating hip fractures among the elderly. Materials and methods: Prospective study covering the number of referrals from Traumatology to Geriatrics in one year. We obtained data on age, sex, type of fracture and surgery, geriatric assessment and repercussion of this activity on the hospital. Results: Over a period of 7 months in 2004, 120 patients were referred to Geriatrics, with a predominance of women and most with hip fractures. The intervention of the Geriatric Department consisted of detecting and compensating prior pathologies, adjusting medication, studying the fall, assessing the surgical risk and preparation for surgery, pain treatment, management of post-surgical complications (anaemia, malnutrition, pressure ulcers, infections, heart failure, etc.), early weight-bearing, detecting social risk and planning release from hospital. The repercussion of this work on the hospital translated into greater satisfaction among traumatologists, nursing staff and patients, more conditions diagnosed and treated and more complete release reports, thus improving ongoing care and shortening hospital stays. Conclusions: Collaboration between the Traumatology and Geriatric Departments in treating geriatric patients admitted to Traumatology is cost-effective because it prevents complications, rationalises treatment, improves the patients’ functional status and shortens hospitalisation stays

Malnutrition is a potentially modifiable risk factor that may contribute to complications following geriatric hip fracture surgery. The purpose of this study was to investigate the association between preoperative hypoalbuminemia, a marker for malnutrition, and complications during the thirty days following surgery for geriatric hip fracture. The American College of Surgeons National Surgical Quality Improvement Program was used to conduct a retrospective cohort study of geriatric patients (>65 years) undergoing surgery for hip fracture. Patients without preoperative serum albumin concentration were excluded. Outcomes were compared between patients with and without hypoalbuminemia (defined as serum albumin concentration <3.5g/dL). All comparisons were adjusted for baseline differences between populations. 17,651 Patients were identified. Of these, 8,272 (46.9%) underwent hemiarthroplasty, 759 (4.3%) total joint arthroplasty, 324 (1.9%) percutaneous fixation, 2,445 (13.9%) plate/screw fixation, and 5,833 (33.1%) intramedullary fixation. The prevalence of hypoalbuminemia was 45.9% (Figure 1). The risk for death was strongly associated with serum albumin concentration, with a linear increase in risk observed as albumin fell below 3.5 g/dL (p<0.001; Figure 2). Following adjustment for all demographic, comorbidity, and procedural characteristics, patients with hypoalbuminemia had higher rates of death (9.94% versus 5.53%, adjusted relative risk [RR]=1.54, p<0.001), pneumonia (5.30% versus 3.77%, adjusted RR=1.20, p=0.012), sepsis (1.19% versus 0.53%, adjusted RR=1.90, p<0.001), and hospital readmission (10.91% versus 9.03%, adjusted RR=1.11, p<0.036; Table 1). The present study suggests that hypoalbuminemia is a powerful independent risk factor for death following surgery for geriatric hip fracture. This association persists over-and-above any associations of death with age, sex, body mass index, and comorbidities. Based on these data, we propose that the nutritional status of hip fracture patients should receive greater attention, and that randomized trials testing for efficacy of aggressive postoperative nutritional interventions may be warranted.

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

This paper presents the nutritional status of a geriatric population admitted for hip fracture. Malnutrition is often associated with the advanced age and can be influenced by physical, mental, social and environmental changes. Hip fracture is a major issue and a prior poor nutritional status is associated with higher rates of perioperative complications and prolonged hospital length of stay. Methods: Prospective observational. Prospective observational cohort study performed in a Level one trauma centreincluding 110 consecutive patients admitted for hip fracture. The main outcome measure was the Mini Nutritional Assessment (MNA), a specific tool validated for geriatric population. This questionnaire was performed at admission by an independent assessor, at the same time as a large set of demographic and functional data. Blood samples were tested for blood count and albuminemia. Two groups were constituted and analysed according to a MNA score > 24 (lower limit for normal nutritional status). Factors explored included physical and mental items. Impact of malnutrition was determined on hospital length of stay (HLS), discharge in an adverse location than prior to admission (DAL), complications and mortality rate. The rate of patients with malnutrition (or at risk) in this study is 49.1% (54 patients). Patients with a MNA < 24 are older (83.6 yrs ± 6.5 vs 80.2 ± 8.3, p<0,01), have more comorbidities (Charlson 2.5 vs 1.27, p<0,01), a more impaired mental (MMSE <27 74.1% vs 41.1%, p<0,01) or physical status (MIF 105.3 +/− 26.6 vs 121.8 +/− 6.4, p<0,01). Blood samples are not selective to detect malnutrition (p=0,64). Malnutrition is associated with a longer HLS (25.2 days +/− 24.2 vs 14.2 +/− 9.0, p<0,01), a greater DAL (58.9% vs 38.2%, p=0,02) and a higher 6 months mortality rate (16.7% vs 3.6%, p=0,02). The prevalence of malnutrition in a geriatric population admitted for hip fracture is high. Blood samples at admission have clearly a poor value and a systematic screening with the MNA is mandatory. An early diagnosis will target specific interventions in order to reduce the physical and socio-economic impact of the malnutrition. Future studies should focus on actions in the perioperative stage (fast-track surgery, nutritional protocols, analgesia) and their impact on the socio-economic burden

Capturing objective data of the postoperative changes in the mobility of patients is expected to generate a better understanding of the effect of postoperative treatment. Until recently, the collection of gait-related data was limited to controlled clinical environments. The emergence of accurate wearable accelerometers with sufficient runtime, however, enables the long-term measurement and extraction of mobility parameters, such as “real-world walking speed”. An interim analysis of 1967 hours of actibelt data (3D accelerometer, 100 Hz) from 5 patients (planned total 20) with a femur fracture and 5 patients (planned total 20) with a humerus fracture from a geriatric population at two different sites of the university hospital of the Ludwigs-Maximilian-University in Munich was performed. Mobility data was captured during several days of stationary treatment starting directly after surgery and during a short follow-up visit six weeks after the surgery. Preliminary results show an increase of the mean walking speed between the two visits independent of the type of fracture. Patients with a humerus fracture tended to walk faster than patients with a femur fracture during both visits. The data also reveals an unexpected low level of mobility during the stationary stay. Mobile accelerometry can be used to evaluate different postoperative mobilisation strategies and even provide near-time feedback in geriatric trauma patients

Introduction & aims. Geriatric hip fractures are a challenging clinical problem throughout the world. Hip fracture services have been shown to shorten time to surgery, decrease the cost of admissions, and improve the outcomes. We instituted a geriatric hip fracture program for co management of these injuries by orthopedic and internal medicine teams at our hospital in India. Method. From January 2010 till December 2011, 119 patients with a femoral neck fracture were treated with cemented modular hemiarthroplasty under this program using a cost-effective Indian implant. The cohort included 63 males and 56 females with a mean age of 70.7 years (range 55–98 years). Hypertension (n=42) and diabetes mellitus (n=29) were the most common co morbidities. The follow-up period ranged from 12 to 37 months with an average of 24 months. Results. The surgery was performed within 24 hours of admission in 60.5% (n=72) patients. The use of anti platelet drugs was the most common reason for delay of surgery. The mean length of hospital stay was 10.4 days (range 3–24 days) with 77% (n=92) of patients discharged within 1 week of admission. On follow-up, good to excellent Harris hip scores were seen in 88% of patients with 76% of patients returning to the pre injury ambulatory status. The mortality rate was 6% at 6 months follow-up and 10.9% at 2 years. Conclusions. Our study shows that a hip fracture program can be instituted in India. The program helped us in achieving the goal of early surgery, mobilization, and discharge from hospital with decreased mortality.

Purpose: We reviewed major amputations of the lower limbs in geriatric patients. Material and method: This retrospective study was conducted in patient treated between January 1990 and December 1999. A total of 265 amputations in 209 patients, including 24 revisions and 32 bilateral amputations, were included in the study. Inclusion criteria were the major nature of the amputation requiring prosthetic fitting and patient age (greater than 65 years). Results: The incidence of amputation in our geriatric population was 4 per 10 000. Mean age at amputation was 78 ± 7.5 years. Mean follow-up was 27.8 months. Tibial amputations predominated (123/264, 46.4%). Aetiology factors were basically diabetes mellitus (99/209, 47.4%), and atherosclerosis (85/209, 40.7%). Overall survival at one year was 61.7%, 47.9% at two years and 13.7% at ten years. Survival was better for tibial amputations (p = 0.023). Analysis of 12 comorbiditties revealed that amputated patients had significantly higher mortality when they also had heart failure (p = 0.001), dialysis (p = 0.001), rhythm disorders (p = 0.003), dementia (p = 0.008). Rhythm disorders (p = 0.01) and dementia (p = à.02) usually predicted a femoral level of amputation. The number of surgical revisions required for amputation at a higher level was 9.1% (24/265). Amputations of the contralateral limb were required in 34/209 patients (16.3%) after a mean delay of 19.7 months. Half of our patients were fitted with a prosthesis (53.6%, 112/209). Discussion: We did not find any predominant aetiological factors by level of amputation. Statistical analysis demonstrated that survival depended on the low level of the amputation. Preservation of the knee was an important factor not only for rehabilitation but also for mortality. Survival after femoral amputation and after desarticulation of the knee was the same. Prosthesis fitting was difficult at the femoral level. Mortality depends on four basic comorbidities, heart failure, dialysis, rhythm disorders and dementia. Addition of comorbidities for a given patient has a significant effect and is not compatible with survival greater than five years

Short-stem total hip arthroplasty (THA) has primarily been recommended for young and active patients, mainly due to its bone preserving philosophy. Elderly patients, however, may also benefit of a minimally invasive technique due to the short and curved implant design. The purpose of this study was to compare the clinical and radiological outcomes as well as perioperative complications of a calcar-guided short stem between a young (75 years) population. Data were collected in a total of 5 centers, and 400 short stems were included as part of a prospective multicentre observational study between 2010 and 2014 with a mean follow-up of 49.2 months. Clinical and radiological outcomes were assessed in both groups. Secondary outcomes such as perioperative complications, rates and reasons for stem revision were also investigated. No differences were found for the mean visual analogue scale (VAS) values of rest pain, load pain, and satisfaction. Harris Hip Score (HHS) was found to be slightly better in the young group. Comparing both groups, no statistically significant differences ere found in the radiological parameters that were assessed (stress-shielding, cortical hypertrophy, radiolucency, osteolysis). Aseptic loosening was the main cause of implant failure in younger patients whereas in elderly patients, postoperative periprosthetic fractures due to accidental fall was found to be the main cause for stem revision. These short-term results are encouraging towards the use of a cementless short stem in the geriatric population. According to our findings, advanced age and potentially reduced bone quality should not necessarily be considered as contra-indications for calcar-guided short-stem THA but careful and reasonable selection of the patients is mandatory. Longer follow up is necessary in order to draw safer conclusions

Geriatric hip fracture patients have a 14-fold higher 30-day mortality than their age matched peers. Up to 50% of these patients receive blood transfusion perioperatively. Both restrictive and liberal transfusion policies are controversial in this population. Aim: The longitudinal description of transfusion practice in geriatric hip fracture patients in a major trauma centre. An 8-year (2002–2009) retrospective study was performed on patients over the age of 65 undergoing hip fracture fixation. Yearly transfusion rate; the influence of transfusion on 30-day, 90-day and 1-year mortality and length of stay (LOS) was investigated. On admission haemoglobin (Hb), pre-transfusion Hb and post-transfusion Hb and their effect on transfusion requirement and mortality was also reviewed. The yearly changes in on-admission and pre-transfusion Hb were also examined. The influence of comorbidities, timing, procedure performed and operation duration on transfusion requirement and mortality was also studied. From the 3412 patients, 35% (1195) received transfusion during their hospital stay. There was no change in age, gender and co-morbidities during the study. Thirty-day mortality improved from 12.4% in 2002 to 7% in 2009. The transfusion rate showed a gradual decrease from the highest of 48.3% (2003) to 22.9% (2009) (Pearson correlation - R2 = −0.707, p=0.05). There was no change during the study period in on-admission and pre-transfusion Hb. The mortality for non-transfused and transfused patients was [9.6% vs. 10.3 % (30-day)], [17.2% vs. 18.4%(90-day)] and [27% vs. 30.5%(1-year), p=0.031]. LOS was 11±9 for non-transfused patients and 13±10 (p<0.001) for transfused patients. Patients with more comorbidities experienced a higher transfusion rate, (0 – 31%, 1 – 38%, 2 – 46%, 3 – 57%), (Pearson Chi-squared, p<0.001). The need for transfusion by different procedures in decreasing order was 47.6% intramedullary device, 44.0% DHS, 25.2% cemented hemiarthroplasty, 23.6% Austin-Moore, and 5.5% cannulated screws. The length of the operation increases the chance of transfusion (<1hrs, – 33%, 1–2hrs – 35%, 2–3hrs – 41%, >3 hours – 65%), (Pearson Chi-squared, p=0.010). Preoperative waiting time had no influence on transfusion frequency (<24hrs – 36%, 24–48hrs – 34%, 48–96hrs – 36%, >96hrs – 33%), (Pearson Chi-squared, p=0.823). The percentage of transfused geriatric hip fracture patients halved during the eight-year period without changes in demographics and co-morbidities. Perioperative transfusion of hip fracture patients is associated with higher 1-year mortality and increased LOS. A more restrictive transfusion practice has been safe and may be a factor in the improved 30-day mortality

Introduction: The optimal management of ankle fractures in the elderly is controversial, with wide variation in the complication rates reported in the literature. Achieving a satisfactory outcome is essential as reduced mobility exacerbates pre-existing morbidity and diminishes the likelihood of independent living. However, in elderly patients surgery carries increased risks due to osteoporosis, poor skin condition and decreased vascularity. Methods: We performed a retrospective review of outcome and complications in patients over 70 years of age with ankle fractures. Patients were admitted for manipulation under anaesthetic and application of cast (MUA) or open reduction and internal fixation (ORIF). Data were retrieved from medical and nursing notes relating to pre-operative functioning, type of injury, operative procedure and outcome. All X-rays were also reviewed to confirm fracture grade and union. Results: A total of 134 patients over the age of 70 were admitted for management of ankle fractures during January 1995 and December 2003 and 117 of these were included in the study. 84 were operatively treated for ankle fractures and a further 27 patients underwent MUA. The mean age in both groups was 76 and there was a female predominance in both groups (89% in MUA, 79% in ORIF). 14.8% of the conservatively managed group were nursing home residents compared to 2.4% of the operatively treated group. The groups were similar with respect to ASA grade and co-morbidities. The median length of stay was shorter for the conservatively managed group (4 vs. 6 days). 7.5% of the MUA group required a second intervention compared to 4.5% of the operatively managed group. There were two below knee amputations in the operatively managed group, both related to open fractures, and one arthrodesis in each group. There were three wound complications in the operatively managed group. The rate of postoperative medical complications was the same in both cohorts. 7.4% of patients treated with MUA and 1.1% of patients treated operatively had reduced mobility at final follow-up. Conclusion: The decision-making process for treatment of ankle fractures in the geriatric population is challenging. We observed significantly better functional results in the ORIF group than the MUA group. These results indicate that open reduction and internal fixation of ankle fractures in geriatric patients is efficacious and safe in selected patients

Objective: To evaluate the results of cannulated screw fixation for subcapital neck of femur fractures in our unit. Materials and Methods: 104 patients underwent the above procedure in our unit over a two year period (Jan 2006 – Dec 2007). The case notes and xrays of these patients were reviewed retrospectively. The age group varied between 31 and 100 years. Results: There was 20% incidence of complications. There were 9 cases of AVN and 10 cases of screws backing out and I case of subtrochanteric fracture. Of the 9 cases of AVN 3 were below 73 years of age and the rest had a mean age of 90.3 years. Conclusion: There is a high incidence of AVN in geriatric group requiring further surgery and cannulated screws fixation is not the optimal choice in geriatric group for varied reasons. Further review is to be carried out looking for the specific reasons of failure

The benefit of using a long intramedullary device for the treatment of geriatric intertrochanteric hip fractures is unknown. The InterTAN device (Smith and Nephew, Memphis TN) is offered in either Short (180–200 mm) or Long (260–460 mm) constructs and was designed to provide stable compression across primary intertrochanteric fracture fragments. The objective of our study was to determine whether Short InterTANs are equivalent to Long InterTANs in terms of functional and adverse outcomes for the treatment of geriatric intertrochanteric hip fractures. 108 patients with OTA classification 31A–1 and 31A–2 intertrochanteric hip fractures were included in our study and prospectively followed at one of four Canadian Level-1 Trauma Centres. Our primary outcomes included two validated primary outcome measures: the Functional Independence Measure (FIM), to measure function, and the Timed Up and Go (TUG), to measure motor performance. Secondary outcome measures included blood loss, length of procedure, length of stay and adverse events. A pre-injury FIM was measured by retrospective recall and all postoperative outcomes were assessed on postoperative day 3, at discharge, at 6 weeks, 3 months, 6 months and 12 months postoperatively. Unpaired t-tests and Chi-square tests were used for the comparison of continuous and categorical variables respectively between the Short and Long InterTAN groups. A statistically significant difference was defined as p<0.05. Our study included 71 Short InterTAN and 37 Long InterTAN patients with 31A–1 and 31A–2 intertrochanteric hip fractures. Age, sex, BMI, side, living status and comorbidities were similar between the two groups. The mean operative time was significantly lower in the Short InterTAN group (61 mins) as compared to the Long InterTAN group (71 mins)(p0.05). There were 5 periprosthetic femur fractures in the short InterTAN group versus 1 in the long InterTAN group. Non-mechanical adverse outcomes such as myocardial infarction, pulmonary embolism, urinary tract infections, pneumonia and death all had similar incidence rates between the two InterTAN groups. Both the Short and Long InterTAN patient cohorts displayed similar improvements in performance and overall function over the course of a year following intertrochanteric hip fracture fixation. The recorded operative times for Short InterTAN fixation were significantly shorter than those recorded for the Long InterTAN patients. Alternatively, a significantly higher proportion of Short InterTAN patients sustained periprosthetic femur fractures within a year of implantation as compared to the Long InterTAN group

Cemented modular metal backed total hip prostheses have the theoretical advantage to allow different inlays to be used. Asymetric or snap inlays are some of the options. First attempts with this kind of implant failed due to PE quality. A novel implant has been specifically designed and constructed for the use of cement. In vitro testing has shown results equal to other cemented cups. Aim of this study is to investigate the first clinical results of this implant with special consideration to intraoperative complications, intraoperative change of inlays, postoperative complications and clinical results. Patients and Methods: Study setup was prospective, location a university hospital, approval for this study was granted by the local ethical committee. Inclusion criteria were patients with a biological age over 70 years that suffered a recent fractured neck of femur with the general indication for arthroplasty. Exclusion criteria were the inability for full informed consent, ASA IV and current infection. Thirty patients were included in this study. Mean age was 78.6 years (55.1 to 88.6), 23 patients were female (77%). The mean BMI was 25.3 (17.5–41). The implant under investigation was a cemented modular acetabular component (C-MIC, ESKA Implants, Germany). The inlays are manufactured of highly crosslinked polyethylene. The standard protocols regarding DVT prophylaxis and antibiosis for HHS and the Barthel index. Results: Implantation of the C-MIC component was possible in all cases. In 1 case (3.3%) the inlay was changed and replaced by an asymmetrical anti-luxation inlay intraoperatively as there was a luxation tendency. There were no other intraoperative complications. There was no case of infection or significant hematoma. In 1 case there was a DVT of the lower leg diagnosed by ultrasound on day 21. The mean Barthel index preop. was determined with 96.5 of 100, the mean Harris Hip Score with 89. At 3 months F/U the Barthel index was mean 96.1, at 6 months 96. The Harris Hip Score at 3 months was mean 72 points (17 pts below the preoperative status), at 6 months mean 79 points (10 pts below preoperative status). Discussion: The C-MIC acetabular component does not show increased complication rates when compared to published results of hemiarthroplasty. The Barthel index as an outcome measurement of mobility and activities of daily living showed a return to the preoperative level. The HHSshowed a satisfactory result at 12 weeks, it also showed that patients of a geriatric population have problems to regain their full hip function after a fractured neck-of-femur. We can conclude that the C-MIC acetabular component is safe to use. Due to limitations of this study we are not able to state if THA is superior to hemiarthroplasty in geriatric patients

Aim

Prosthetic joint replacement is more commonly done in the elderly group of patients due to an increase pathology related to joint degeneration that comes with age. In this age group is also more frequent having underling condition that may predispose to a prosthetic joint infection. Also, the pharmacological intervention in those patients may play an important role as a risk factor for infection after joint replacement surgery. The use of oral anticoagulants seems to be particularly increased in elderly patients but there aren't enough data published to support an association between prosthetic joint infection and the use of oral anticoagulants.

Identifying risk factors in elderly patients age >75 years old with a special focus on the oral anticoagulation therapy is the aim of the study.

Purpose. The hip fracture has been increasing as the aging population continues to grow. Hip fracture patients are more susceptible to blood loss and venous thromboembolism (VTE). The objective of this study was to assess the efficacy and safety of tranexamic acid (TXA) in fracture patients undergoing fast-track hemiarthroplasty. Methods. 609 hip fracture patients undergoing hemiarthropalsty from January 2013 to September 2016 were prospectively selected. 289 patients received 15 mg/kg TXA prior to surgery, and the remaining 320 patients received no TXA. All the patients received a fast-track program including nutrition management, blood management, pain management, VTE prophylaxis and early mobilization and early intake. The primary outcome was transfusion requirement, other parameters such as blood loss, hemoglobin (Hb) level, VTE, adverse events and length of hospital stay were also compared. Multivariate logistic regression analysis and meta-analysis were also performed to identify the risk factors of transfusion and confirm the results of current study. Results. Transfusion of at least 1U of erythrocyte blood cell occurred in 25 patients (8.65%) in treatment group and in 77 (24.06%, OR=0.299, p<0.001) in control group. The mean level of Hb on POD 1 (111.70±18.40 g/L) and POD 3 (108.16±17.25 g/L) in TXA group were higher than control group (107.29±18.70 g/L, p= 0.008; 104.22±15.16 g/L, p= 0.005 respectively). More patients get off bed to ambulate within 24 hours after surgery in TXA group (37.02% Vs 26.25%, p= 0.004). And the length of hospital stay was shorter (11.82±4.39 Vs 15.96±7.30, p= 0.003). No statistical significance were detected regarding VTE and other adverse events. Logistic regression analysis showed that the relative odds reduction after adjustment for these covariates was 67% (OR= 0.327, 95%CIs= 0.197 to 0.544) in favor of tranexamic acid. Other risk factors included preoperative hemoglobin level, operation time, VTE prophylaxis. Pooling the data showed that tranexamic acid led to a significant reduction in transfusion (OR= 0.33, 95%CIs= 0.25 to 0.43) without sacrificing safety (OR= 0.70, 95%CIs= 0.25 to 1.97). Conclusion. Tranexamic acid was effective and safe to reduce blood loss and transfusion in geriatric hip fracture patients undergoing fast-track hemiarthroplasty

There is a high rate of mortality in elderly patients who sustain a fracture of the hip. We aimed to determine the rate of preventable mortality and errors during the management of these patients. A 12 month prospective study was performed on patients aged > 65 years who had sustained a fracture of the hip. This was conducted at a Level 1 Trauma Centre with no orthogeriatric service. A multidisciplinary review of the medical records by four specialists was performed to analyse errors of management and elements of preventable mortality. During 2011, there were 437 patients aged > 65 years admitted with a fracture of the hip (85 years (66 to 99)) and 20 died while in hospital (86.3 years (67 to 96)). A total of 152 errors were identified in the 80 individual reviews of the 20 deaths. A total of 99 errors (65%) were thought to have at least a moderate effect on death; 45 reviews considering death (57%) were thought to have potentially been preventable. Agreement between the panel of reviewers on the preventability of death was fair. A larger-scale assessment of preventable mortality in elderly patients who sustain a fracture of the hip is required. Multidisciplinary review panels could be considered as part of the quality assurance process in the management of these patients.

Purpose: To assess the effect of regional versus general anesthesia on transcranial cerebral oxygen saturation (rSO. 2. ) in elderly patients undergoing fractured proximal femur repair. Materials and Methods: Prospective, randomized, open-label study. 60 geriatric patients were randomized to receive either general (Group GA) or spinal (Group S) anesthesia. In all cases frontal rSO. 2. (INVOS. ®. 5100, SOMANETICS, Troy, Michigan, USA) was measured for a 10 minute pre-operative control period, throughout the surgical procedure and for 10 minutes postoperatively. If a drop in rSO. 2. below baseline occurred, the following were instituted in order to improve cerebral oxygenation: normotension was ensured, the neck vessels were checked and cleared of extrinsic obstruction and the F. I. O. 2. was increased. Results: The incidence of a decrease in rSO. 2. below base-line preoperative levels was significantly (p < 0.0001) higher in Group S. However, the number of patients in whom at least one dip below baseline was recorded was similar between the groups. By contrast, general anesthesia was associated with a significantly higher rSO. 2. when compared to spinal anesthesia. This is attributed to the volatile anesthetic agent induced reduction in the cerebral metabolic rate. Logistic regression revealed no correlation between changes in blood pressure, heart rate or peripheral oxygen saturation and the incidence of rSO. 2. dips below baseline. Conclusion: rSO. 2. is likely patient specific and independent of the anesthetic technique administered. Therefore we support the utility of cerebral oximetry in this population in order to detect cerebral desaturation and correct reversible causes such as relative hypotension and neck vessel obstruction. Choice of anesthetic technique should still be tailored to individual patient needs

Aims

The aims of this study were to evaluate the incidence of postoperatively restricted weight-bearing and its association with outcome in patients who undergo surgery for a fracture of the hip.

Aims

Total hip arthroplasty (THA) with dual-mobility components (DM-THA) has been shown to decrease the risk of dislocation in the setting of a displaced neck of femur fracture compared to conventional single-bearing THA (SB-THA). This study assesses if the clinical benefit of a reduced dislocation rate can justify the incremental cost increase of DM-THA compared to SB-THA.

Aims

The primary aim was to determine the influence of COVID-19 on 30-day mortality following hip fracture. Secondary aims were to determine predictors of COVID-19 status on presentation and later in the admission; the rate of hospital acquired COVID-19; and the predictive value of negative swabs on admission.

All patients over 65 yrs with an ISS greater than 15 attending Edinburgh Royal Infirmary between 1997 and 2000 were prospectively entered into the study. Patients were followed until death or discharge home. The patients were divided into, group 1 [patients who survived], and group 2 [those who died.]

A total of 72 patients were included in the study, 42 males and 31 females. 42 patients survived, and 31 died.

Group 1 consisted of 29 males and 15 females with an average age of 75.23yrs. Group 2 consisted of 13 males and 18 females with an average age of 78.05yrs. All incidents involved blunt trauma. The three main mechanisms of injury were RTA, Fall less than 2 meters, and Fall greater than 2 meters.

Five patients required intubation in group 1 and 12 patients in group 2.The average GCS was lower in group 1 compared to the group 2. All Injuries with AIS of greater than 3 were analysed. The total number of injuries was greater in the group 2. Group 1 required 214 days in HDU/ITU and a total of 943 in-patient days. Group 2 in comparison needed 62 HDU/ITU days and 169 in-patient days. The major cause of death was head and spinal injury 11 (35%), and Multiple injuries 9 (29%).

A total number of 1952 days were spent in rehabilitation prior to discharge, with an average of 46.48 days. Post trauma the level of independence was significantly reduced.

The injuries are exclusively blunt and in the majority of cases secondary to motor vehicle accidents. Predictors of mortality appear to include, intubation, head and neck injuries, GCS, and chest injuries. Current outcome scores correlate inaccurately. These patients require long hospital stays with a large amount of intensive care input. After discharge rehabilitation is universally required. These patients place a large demand on the NHS and social services; the total cost of their care was approximately £2,500,000.

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. Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery. Methods. This observational cohort study enrolled consecutively admitted patients with a proximal femoral fracture, for which surgery was performed between 1 January 2018 and 11 January 2021 in two level II trauma teaching hospitals. Patients with medical indications to postpone surgery were excluded. A total of 1,803 patients were included, of whom 1,428 had surgery < 24 hours and 375 had surgery ≥ 24 hours after admission. Results. Prolonged total length of stay was found when surgery was performed ≥ 24 hours (median 6 days (interquartile range (IQR) 4 to 9) vs 7 days (IQR 5 to 10); p = 0.001) after admission. No differences in postoperative length of hospital stay nor in 30-day mortality rates were found. In subgroup analysis for time frames of 12 hours each, pressure sores and urinary tract infections were diagnosed more frequently when time to surgery increased. Conclusion. Longer time to surgery due to non-medical reasons was associated with a higher incidence of postoperative pressure sores and urinary tract infections when time to surgery was more than 48 hours after admission. No association was found between time to surgery and 30-day mortality rates or postoperative length of hospital stay. Cite this article: Bone Joint J 2022;104-B(12):1369–1378

Aims. The optimal choice of management for proximal humerus fractures (PHFs) has been increasingly discussed in the literature, and this work aimed to answer the following questions: 1) what are the incidence rates of PHF in the geriatric population in the USA; 2) what is the mortality rate after PHF in the elderly population, specifically for distinct treatment procedures; and 3) what factors influence the mortality rate?. Methods. PHFs occurring between 1 January 2009 and 31 December 2019 were identified from the Medicare physician service records. Incidence rates were determined, mortality rates were calculated, and semiparametric Cox regression was applied, incorporating 23 demographic, clinical, and socioeconomic covariates, to compare the mortality risk between treatments. Results. From 2009 to 2019, the incidence decreased by 11.85% from 300.4 cases/100,000 enrollees to 266.3 cases/100,000 enrollees, although this was not statistically significant (z = -1.47, p = 0.142). In comparison to matched Medicare patients without a PHF, but of the same five-year age group and sex, a mean survival difference of -17.3% was observed. The one-year mortality rate was higher after nonoperative treatment with 16.4% compared to surgical treatment with 9.3% (hazard ratio (HR) = 1.29, 95% confidence interval (CI) 1.23 to 1.36; p < 0.001) and to shoulder arthroplasty with 7.4% (HR = 1.45, 95% CI 1.33 to 1.58; p < 0.001). Statistically significant mortality risk factors after operative treatment included age older than 75 years, male sex, chronic obstructive pulmonary disease (COPD), cerebrovascular disease, chronic kidney disease, a concomitant fracture, congestive heart failure, and osteoporotic fracture. Conclusion. Mortality risk factors for distinct treatment modes after PHF in elderly patients could be identified, which may guide clinical decision-making.

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.

Introduction. Open fractures are fortunately rare but pose an even greater challenge due to poor soft tissues, in addition to poor bone quality. Co-morbidities and pre-existing medical conditions, in particular, peripheral vascular diseases make them often unsuitable for free flaps. We present our experience in treating severe open fractures of tibia with Acute Intentional Deformation (AID) to close the soft tissues followed by gradual correction of deformity to achieve anatomical alignment of the tibia and fracture healing with Taylor Spatial Frame. Materials and Methods. We treated 4 geriatric (3 female and 1 male) patients with Gustillo-Anderson III B fractures of the tibia between 2017–18. All were unfit to undergo orthoplastic procedures (free flap or local flaps). The age range is 69 yrs to 92 years. Co-morbidities included severe rheumatoid arthritis, multiple sclerosis and heart failure. The procedure involved wound debridement, application of two ring Taylor Spatial Frame, acute deformation of the limb on the table to achieve soft-tissue closure/approximation. Regular neurovascular assessments were performed in the immediate post-operative period to monitor for compartment syndrome and nerve compression symptoms. After 7–10 days of latent period, the frame was gradually manipulated, according to a method we had previously published, to achieve anatomical alignment. The frame was removed in clinic after fracture healing. Results. Time in frame ranged from 1.5 months to 7 months. In one patient (92 yr old with an open fracture of the ankle) hindfoot nail was inserted after soft-tissue closure was achieved at 1.5 months, and frame removed. We achieved complete healing of soft tissue wounds without any input from plastic surgeons in all patients. All fractures healed in anatomical alignment. 3 patients had one episode of superficial pin infection each requiring 5 days of oral antibiotics. None of the patients developed a deep infection. Conclusions. Acute intentional deformation (AID) with Taylor Spatial Frame achieves good closure of soft tissues in physiologically compromised geriatric patients who were deemed unfit for plastic surgery. We also achieved fracture healing in all four cases without any major complications

Abstract. Introduction. Displaced olecranon fractures in the elderly are challenging due to associated comorbidities, poor tissue quality, high risk of complications, and the possible need for implant removal. Treatment options with such fractures range from non-operative management to internal fixation with various types of implants. Currently, there is no consensus on the treatment of olecranon fractures in the elderly with relatively low functional demand. Aim. The aim of this systematic review was to analyse the clinical outcomes of various treatment modalities for olecranon fracture in the elderly. Methods. We systematically reviewed the literature covering the treatment of olecranon fractures in the elderly according to PRISMA guidelines. We used search tools of Medline, Embase, Wiley online library, Cochrane and Scopus. Keywords used in the search were Olecranon fracture and Elderly OR Geriatric in all fields. Studies involving patients older than 60 years of age and all modalities of treatment were included. Results. 14 papers studying 270 patients were identified of which, 112 were treated non-operatively, 25 with limited fixation, 98 with tension band wire fixation, 34 with plate fixation, and 1 patient was treated with excision. Conclusions. Nonoperative as well as limited fixation were shown to provide satisfactory results in the elderly. Treatment decisions in this age group should be individualised to factors such as fracture stability, quality of bone & soft tissues, and patient's functional demand. We recommend a treatment protocol for treating olecranon fracture in the elderly based on the above factors

Abstract. Background. Fractures Proximal humerus account for nearly 10 % of geriatric fractures. The treatment options varies. There is no consensus regarding the optimal treatment, with almost all modalities giving functionally poor outcomes. Hence literature recommends conservative management over surgical options. MULTILOC nail with its design seems to be a promising tool in treating these fractures. We hereby report our early experience in the treatment of 37 elderly patients. Objectives. To evaluate the radiological outcome with regards to union, collapse, screw back out/cut through, implant failures, Greater tuberosity migration. To evaluate the functional outcome at the end of 6 months using Constant score. Study Design & Methods. All patients aged >65 years who underwent surgery for 3,4-part fracture proximal humerus using the MULTILOC nail were included in the study after consent. Pre – existing rotator cuff disease were excluded. Within the time frame, a total of 39 patients underwent the said surgery. 2 patients were lost to follow up. All the measurements were taken at the end of 6 months and results tabulated and analysed. Results. Union was achieved in all the 37 patients. There were no varus collapse or screw backout/cut through seen in any of the patients. There was Greater tuberosity migration in 1 patient who underwent revision surgery at 6 weeks. All the patients got a minimum of 70 degrees of abduction and forward flexion. We had 29 excellent, 6 good, 2 fair and none poor results as per Constant scoring system. Study done in Tejasvini Hospital & SSIOT Mangaluru India

Osteoarthritis (OA) of the knee joint is a complex peripheral joint disorder with multiple risk factors. We aimed to examine the relationship between the grade of knee OA and anterior thigh length (ATL). A total of 64 geriatric patients who had no total hip or knee replacement with a BMI of ≥30 were evaluated. Patients' OA severity was determined by two independent experts from bilateral standing knee radiographs according to the Kellgren-Lawrence (KL) grade. Joint cartilage structure was assessed using ultrasonography (US). The ATL, the gastrocnemius medialis (GC), the rectus femoris (RF) and the rectus abdominis (RA) skeletal muscle thicknesses as well as the RF cross-sectional area (CSA) were measured with US. Sarcopenia was diagnosed using the handgrip strength (HGS), 5× sit-to-stand test (5xSST) and bioelectrical impedance analysis. The median (IQR) age of participants was 72 (65–88) years. Seventy-one per cent of the patients (n=46) were female. They were divided into the sarcopenic obese (31.3 %) and the non-sarcopenic obese (68.8%) groups. KL grade of all patients correlated negatively with the ATL (mm) and the thickness of GC (mm) (r= -0,517, p<0.001 and r= -0.456, p<0.001, respectively). In the sarcopenic obese and the non-sarcopenic obese groups, KL grade of the all patients was negatively correlated with ATL (mm) and thickness of GC (mm) (r= -0,986, p<0.001; r= -0.456, p=0.05 and r= -0,812, p=0.002; r= −0,427, p=0.006). KL grade negatively correlated with the RF thickness in the sarcopenic obese group (r= -0,928, p=0.008). In conclusion, OA risk may decrease as the lower extremity skeletal muscle mass increases.

Periprosthetic joint infection (PJI) in geriatric and/or multimorbid patients is an enormous challenge for orthopaedic surgeons. Revision procedures have also been demonstrated to expose patients to higher infection risks. Prior patient stratification according to presumed infection risks, followed by a more potent local antibiotic prophylaxis protocol with selective use of DALBC, is an interesting strategy to decrease the burden of PJI in high risk patients. The PubMed & EMBASE databases were screened for publications pertaining to the utilization of DALBC in cement for infection prophylaxis & prosthesis fixation. 6 preclinical & 7 clinical studies were identified which met the inclusion criteria and were stratified by level of clinical evidence. Only those studies were considered which compared the PJI outcome in the DALBC vs the SALBC group. (1). DALBC have been shown to exert a much stronger and longer lasting inhibition of biofilm formation on many PJI relevant bacteria (gram-positive and gram-negative pathogens) than single gentamicin-only containing cements. (2). DALBC use (COPAL G+C) in the intervention arm of 7 clinical studies has led to a significant reduction of PJI cases in a) cemented hemiarthroplasty procedures (3 studies, evidence level I and III), in b) cemented septic revision surgeries (2 studies, evidence level III), in c) cemented aseptic knee revisions (1 study, evidence level III) and in d) cemented primary arthroplasties in multi-morbid patients (1 study, evidence level III-IV). These benefits were not associated with more systemic side effects or a higher prevalence of broad antimicrobial resistancies. Use of DALBC is likely to be more effective in preventing PJI in high risk patients. The preliminar findings so far may encourage clinicians to consolidate this hypothesis on a wider clinical range

PFFs are an increasing burden presenting to the acute trauma services. The purpose of this study is to show that cemented revision for Vancouver B2/B3 PFFs is a safe option in the geriatric population, allows early pain-free weight bearing and comparable to a control-group of uncemented stems with regard to return to theatre and revision surgery. A retrospective review was conducted of all PFFs treated in a Level 1 trauma centre from 2015-2020. Follow up x-rays and clinical course through electronic chart was reviewed for 78 cemented revisions and 49 uncemented revisions for PFF. Primary endpoints were all cause revision and return to theatre for any reason. Secondary endpoints recorded mobility status and all-cause mortality. In the cemented group there were 73 Vancouver B2, 5 Vancouver B3 PFF; the mean age was 79.7 years and mean radiological follow-up of 11.9 months. In the cementless group there were 32 Vancouver B2 and 17 Vancouver B3 PFFs; with all 49 patients undergoing distally bearing uncemented revision, the mean age was 72.7 years and mean radiological follow-up of 21.3 months. Patients treated with a cemented prosthesis had significantly higher ASA score (2.94 -v- 2.43, p<0.001). The primary endpoints showed that there was no significant difference in all cause revision 3/78 and 5/49 p=0.077, or return to theatre 13/78 -v- 12/49 p=0.142. Secondary endpoints revealed no significant difference in in-hospital mortality. The cementless group were more likely to be mobilising without any aid at latest follow-up 35/49 -v- 24/78 p<0.001. The use of cemented revision femoral component in the setting of PFFs is one option in the algorithm for management of unstable PFFs according to the Vancouver classification. Evidence from this case-control study, shows that the all-cause revision and return to theatre for any cause was comparable in both groups

During aging, tendons demonstrate substantial disruptions in homeostasis, leading to impairments in structure-function. Impaired tendon function contributes to substantial declines quality of life during aging. Aged tendons are more likely to undergo spontaneous rupture, and the healing response following injury is impaired in aged tendons. Thus, there is a need to develop strategies to maintain tendon homeostasis and healing capacity through the lifespan. Tendon cell density sharply declines by ∼12 months of age in mice, and this low cell density is retained in geriatric tendons. Our data suggests that this decline in cellularity initiates a degenerative cascade due to insufficient production of the extracellular matrix (ECM) components needed to maintain tendon homeostasis. Thus, preventing this decline in tendon cellularity has great potential for maintaining tendon health. Single cell RNA sequencing analysis identifies two changes in the aged tendon cell environment. First, aged tendons primarily lose tenocytes that are associated with ECM biosynthesis functions. Second, the tenocytes that remain in aged tendons have disruptions in proteostasis and an increased pro-inflammatory phenotype, with these changes collectively termed ‘programmatic skewing'. To determine which of these changes drives homeostatic disruption, we developed a model of tenocyte depletion in young animals. This model decreases tendon cellularity to that of an aged tendon, including decreased biosynthetic tenocyte function, while age-related programmatic skewing is absent. Loss of biosynthetic tenocyte function in young tendons was sufficient to induce homeostatic disruption comparable to natural aging, including deficits in ECM organization, composition, and material quality, suggesting loss biosynthetic tenocytes as an initiator of tendon degeneration. In contrast, our data suggest that programmatic skewing underpins impaired healing in aged tendons. Indeed, despite similar declines in the tenocyte environment, middle-aged and young-depleted tendons mount a physiological healing response characterized by robust ECM synthesis and remodeling, while aged tendons heal with insufficient ECM

Ankle fractures in the elderly are common and have a mortality rate of 12% within the first year. Treatment is challenging due to osteoporotic bone and patient co-morbidities. Many patients struggle with non-weight-bearing (NWB) and presently there is no consensus in the literature regarding optimum management of these injuries. We hypothesised that early weight-bearing in frail patients, Clinical Frailty scale (CFS) score of 4 or more will reduce morbidity and allow patients to return to their usual place of residence faster without jeopardising clinical outcome. We conducted a retrospective analysis of 80 patients aged over 65 years managed at Fiona Stanley Hospital for ankle fractures between January 2016 and 2018. Patients were divided into two cohorts: 40 patients managed NWB and 40 who were permitted to weight-bear as tolerated (WBAT). Patients were stratified as fit (CFS 1–3) or frail (CFS 4+). Primary outcomes were one-year mortality, return to primary residence at six weeks and complications. Secondary outcomes included length of acute hospital stay and rehab stay. For frail patients, those managed NWB stayed in rehab for 19 days longer (p=0.03) and had 28% more complications (p=0.03). By 6 weeks, fewer patients returned to full weight-bearing (p=0.03) and fewer patients had returned home (p=0.01). For fit patients, there were no significant differences in primary outcomes between NWB and WBAT. Our novel study categorising patients by CSF demonstrates that early mobilisation in frail patients results in improved outcomes. Currently there is no formal treatment protocol for the management of ankle fractures in the elderly, and we hope that our proposed algorithm will assist surgeons at our institution and elsewhere. Our study suggests that WBAT may benefit frail patients. We propose a protocol to assist in the management of geriatric ankle fracture patients based on clinical frailty scores

Sarcopenia is an age-related geriatric syndrome which is associated with subsequent disability and morbidity. Currently there is no promising therapy approved for the treatment of sarcopenia. The receptor activator of nuclear factor NF-κB ligand (RANKL) and its receptor (RANK) are expressed in bone and skeletal muscle. Activation of the NF-κB pathway mainly inhibits myogenic differentiation, which leads to skeletal muscle dysfunction and loss. LYVE1 and CD206 positive macrophage has been reported to be associated with progressive impairment of skeletal muscle function with aging. The study aims to investigate the effects of an anti-RANKL treatment on sarcopenic skeletal muscle and explore the related mechanisms on muscle inflammation and the polarization status of macrophages. Sarcopenic senescence-accelerated mouse P8 (SAMP8) mice at month 8 were treated intraperitoneally with 5mg/kg anti-RANKL (IK22/5) or isotype control (2A3; Bio X Cell) antibody every 4 weeks and harvested at month 10. Senescence accelerated mouse resistant-1 (SAMR1) were collected at month 10 as the age-matched non-sarcopenic group. Ex-vivo functional assessment, grip strength and immunostaining of C/EBPa, CD206, F4/80, LYVE1 and PAX7 were performed. Data analysis was done with one-way ANOVA, and the significant level was set at p≤0.05. At month 10, tetanic force/specific tetanic force, twitch force/specific twitch force in anti-RANKL group were significantly higher than control group (all p<0.01). The mice in the anti-RANKL treatment group also showed significantly higher grip strength than Con group (p<0.001). The SAMP8 mice at month 10 expressed significantly more C/EBPa, CD206 and LYVE1 positive area than in SAMR1, while anti-RANKL treatment significantly decreased C/EBPa, CD206 and LYVE1 positive area. The anti-RANKL treatment protected against skeletal muscle dysfunctions through suppressing muscle inflammation and modulating M2 macrophages, which may represent a novel therapeutic approach for sarcopenia.

In Alberta there are over 2,700 hip fractures per year costing the health system over $24 million in acute care costs alone. 50% of hip fracture patients have had a prior fragility fracture as a result of underlying osteoporosis (OP) that has never been assessed or appropriately treated. The Fracture Liaison Service (FLS) in Alberta aims to improve appropriate osteoporosis care, highlight and address gaps within seniors care through OP management, and provide a geriatric syndrome triage service. The FLS has developed a linkage with the Emergency Department (ED) geriatric team whereby hip fracture patients are identified in ED using a screening tool for geriatric syndromes prior to their surgery, allowing the FLS to follow through on comorbidities likely contributing to falls. An inpatient orthopaedic unit with a dedicated Registered Nurse (RN) and a Care of the Elderly Physician see and assess hip fracture patients after surgery for appropriate osteoporosis management and treatment. Screening tools have been developed to quickly detect underlying dementia and to quantify frailty to determine life expectancy and appropriate osteoporosis therapy. Patients are also referred to Geriatric Assessment Units and fall prevention programs. Patients are then contacted in the community at 3, 6,9,12 months by the FLS RN to follow up on osteoporosis therapy, and arrange other needed tests (i.e. bone mineral density, vitamin D) as needed. Information is sent to their family physician with all results. Prior to the patient's discharge from the FLS at one year, a final hand-over letter from the program will be provided outlining the plan of care for the patient. The FLS launched in June 2015 at the Misericordia hospital in Edmonton, Alberta (with plans to expand provincially). Currently 3 out of 4 hip fracture patients per week are being identified in the ED. Ninety-eight hip fracture patients have been identified post-surgery, with 71 patients eligible for enrollment in the program (five deceased patients). Sixty-six (50%) of those enrolled were discharged on osteoporosis medication compared to 8% prior to the program initiation. Seventeen (26%) of those were new medication starts. Of those not started, 7(11%) was patient choice. 11(31%) will be reassessed at 3 months for appropriate therapy. Nineteen (27%) of patients were referred to other inpatient or outpatient programs (i.e. falls, memory). Three month follow up calls have begun with patients for further data collection and a full 1 year qualitative and quantitative evaluation will be done. The implementation of an FLS with dedicated personnel to proactively manage and treat patients with appropriate investigations and interventions can close the care gap that exists in OP care. It also addresses gaps in senior care and provides appropriate referral to community geriatric programs, to improve quality of life and prevent future fractures

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

Direct oral anticoagulant (DOAC) use is becoming more widespread in the geriatric population. Depending on the type of DOAC, several days are required for its anticoagulant effects to resorb, which may lead to surgical delays. This can have an important impact on hip fracture patients who require surgery. The goal of the current study is to compare surgical delays, mortality and complications for hip fracture patients who were on a DOAC to those who were not. A retrospective cohort study was conducted at a university hospital in Sherbrooke. All hip fracture patients between 2012 and 2018 who were on a DOAC prior to their surgery were included. These patients were matched with similar patients who were not on an anticoagulant (non-DOAC) for age, sex, type of fracture and date of operation. Demographic and clinical data were collected for all patients. Surgical delay was defined as time of admission to time of surgery. Mortality and complications up to one year postoperative were also noted. Each cohort comprised of 74 patients. There were no statistically signification differences in Charleson Comorbidty Index and American Society of Anesthesiologists scores between cohorts. Surgical delay was significantly longer for DOAC patients (36.3±22.2 hours vs. 18.6±18.9 hours, p < 0 .001). Mortality (6.1%) and overall complication (33.8%) rates were similar between the two cohorts. However, there were more surgical reinterventions in DOAC patients than non-DOAC ones (16.2% vs. 0.0%, p < 0 .001). Among DOAC patients, mortality was greater for those operated after 48 hours (23.1% vs. 3.3%, p < 0 .05) and complications were more frequent for those operated after 24 hours (52.0% vs. 37.5%, p < 0 .05). Direct oral anticoagulant (DOAC) use in hip fracture patients is associated with longer surgical delays. Longer delays to surgery are associated with higher mortality and complication rates in hip fracture patients taking a DOAC. Hip fracture patients should have their surgery performed as soon as medically possible, regardless of anticoagulant use

Introduction. The length of hospital stay following a hip fracture has decreased significantly during the past decades. Knowing that a hip fracture patient is often one with several comorbidities and high mortality, is it possible to further decrease the length of stay without compromising the quality of care?. Setting. Prior to November 2007 a hip fracture patient at Svendborg Hospital would be admitted to the orthopedic department. Postoperatively the patient would be treated by the orthopedic surgeons. If needed a geriatric consult could occur. If the patient was eligible she could be transferred to the geriatric department for further rehabilitation. After November 2007 eight orthopedic beds were dedicated to hip fracture patients, in an orthogeriatric setting. The patient was treated operatively by the orthopedic surgeons, and then a geriatric consultant was responsible for the rest of the stay. Nurses and therapists were dedicated to the care of hip fracture patients, and had recieved special training regarding. The patient would stay in the same bed throughout the hospitalisation. Material. 224 consecutive hip fracture patients prior to November 2007 treated in a classic orthopedic department compared to 224 consecutive hip fracture patients after November 2007 treated in the orthogeriatic department. Of the 224 patients treated prior to November 2007 117 were eventually transferred to the geriatric department. Result. the overall mean hospital stay in the classic orthopedic department was 17.5 days (range 2–58 days, 95% CI 15.9–18.8 days). Patients (N=107), who were not transferred to the geriatric department had a mean of 8,7 days, whereas those who were transferred had a mean stay of 25,5 days. After November 2007 the overall mean length of stay was 11.5 days (range 1–38, 95% CI 10.5–11.9 days). The hip fracture patients spent 1,388 less days in hospital when admitted to the orthogeriatric setting as compared to the classic orthopedic setting. The 30 day mortality was 11,3% in the group prior to November 2007 compared to 9,8% in the group after November 2007. Conclusion. Changing the setting in which hip fracture patients are treated, significantly reduces the overall length of stay (p<0.0000), without compromising mortality. It involves an interdisciplinary setting with dedicated nurses and therapists. The hip fracture patient is first and foremost regarded as a geriatric patient and thus treated postoperatively by geriatric consultants

Geriatric syndromes could lead individuals to exhibit significant mobility and psychological deficits resulting in significant healthcare costs. Thus, identifying strategies to delay aging, or prevent progressive loss of tissue homeostasis could dramatically restore the function and independence of millions of elderly patients and significantly improve quality of life. One of the fundamental properties of aging is the accumulation of senescent cells and senescence associated secretory phenotypes (SASPs) that needs to be treated in wide range of therapeutics including orthobiologics. Senolytic compounds selectively target and kill senescent cells and inhibit anti-apoptotic pathways that are upregulated in senescent cells thereby inducing apoptotic cell death and abrogating systemic SASP factors. We have also shown that blocking fibrosis with Losartan (TGF-β1 blocker) can improve musculoskeletal healing and cartilage repair by reducing the amount of fibrosis. Thus, we hypothesize that administration of anti-fibrotic agents will enhance the beneficial effects of orthobiologics. The safety and efficacy of several senolytic and anti-fibrotic agents to delay age-related dysfunction and improve the function of orthobiologics have been demonstrated in a variety of animal models (in vivo). Overall, our innovative approaches target senescent cells (inflammation) and TGF-β1 (fibrosis) to enhance the clinical efficacy and use of orthobiologics for musculoskeletal repair. We will also discuss ongoing active clinical trials on orthobiologics to aiming at evaluating the safety and efficacy of senolytic agent (Fisetin) and anti-fibrotic agent (Losartan), used independently or in combination, to enhance the beneficial effects of orthobiologics for patients afflicted with musculoskeletal diseases and conditions

Hip fracture care is complex multi-disciplinary. We hypothesise that quality of care is affected by variance in resources between ‘in-hours’ (Monday-Friday, 0800–1700) and ‘out-of-hours’ services. This prospective multicentre national cohort study assessed quality of care by evaluating adherence to the evidence-based Scottish Standards of Care for Hip Fracture Patients. Data was collected by the Scottish Hip Fracture Audit for 15174 patients admitted to any of 22 Scottish hospitals from January 2014-April 2018. 11197/15174 (73.8%) patients were admitted out-of-hours. They were significantly less likely to meet the following Standards: ED Big-6-Bundle (OR 0.85, p= 0.002); Time in ED <4 hours (OR 0.76, p< 0.001); avoidance of repeated fasting (OR 0.80, p< 0.001), and avoidance of prolonged fluid fasting (OR 0.83, p< 0.001). Out-of-hours admissions were more likely to receive: geriatric assessment <3 days (OR 1.16, p< 0.001); OT input <3 days (OR 1.10, p= 0.013), and PT input <2 days (OR 1.44, p< 0.001). There were no significant differences for: Time to Theatre <36 hours; Inpatient Care Bundle <24 hours, and Post-op Day 1 Mobilisation. Quality of hip fracture care is affected by time of admission. ED care is poorer out-of-hours, which may reflect limited resources, and out-of-hours admissions are more likely to be excessive fasted excessively. Weekday in-hours admissions are less likely to receive geriatric and allied health professional input in the days following admission, which may reflect the reduced weekend services. Examination of out-of-hours service organisation is required for the pursuit of consistent, equitable care for hip fracture patients

Hemiarthroplasty (HA) and total hip arthroplasty (THA) have both been well described as effective methods of management for displaced femoral neck fractures in the elderly. THA has superior functional outcomes and lower long-term revision rates, while HA is associated with lower dislocation rates and faster operative times. While HA remains an appropriate management option in low-demand patients, it is commonly complicated by acetabular erosion. However, there is no consensus about the preferred method of treatment in self-sufficient, physically active patients with normal cognition. The aim of this study was to evaluate the impact of age in geriatric patients with acetabular wear after bipolar HA. We retrospectively reviewed the records of all cases of femoral neck fractures treated with bipolar HA in our institution, during the period 2013 – 2020. According to the age at the time of fracture, patients were separated in 3 groups: Group A (age 70 – 75), group B (age 75 – 80) and group C (age > 80). Acetabular wear was defined as failure of the acetabulum, which needed revision to THA. A total of 1410 patients (861 females and 549 males, mean age 77,2 years) were included in the study. 359 patients were included in Group A, 592 in Group B and 459 in Group C. Mean follow-up was 3.2 years. There were no significant differences in sex distribution, injury side, fracture pattern, BMI, ASA score, bipolar head diameter and leg length discrepancy among the 3 groups. The incidence of acetabular wear and need for revision to THA was 6.13%, 4.22% and 1.96% respectively (p = 0.009). The higher rate of acetabular wear in patients less than 75 years suggests that THA is a more viable option for these patients. In group 75–80 years old decision for HA or THA should be made upon patient's activity status and biological age while above the age of 80 years old, Hemi seems to be the preferred solution

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

Introduction and Objective. Plating of geriatric distal femoral fractures with Locking Compression Plate Distal Femur (LCP–DF) often requires augmentation with a supplemental medial plate to achieve sufficient stability allowing early mobilization. However, medial vital structures may be impaired by supplemental medial plating using a straight plate. Therefore, a helically shaped medial plate may be used to avoid damage of these structures. Aim of the current study was to investigate the biomechanical competence of augmented LCP–DF plating using a supplemental straight versus helically shaped medial plate. Materials and Methods. Ten pairs of human cadaveric femora with poor bone quality were assigned pairwise for instrumentation using a lateral anatomical 15-hole LCP–DF combined with a medial 14-hole LCP, the latter being either straight or manually pre-contoured to a 90-degree helical shape. An unstable distal femoral fracture AO/OTA 33–A3 was simulated by means of osteotomies. All specimens were biomechanically tested under non-destructive quasi-static and destructive progressively increasing combined cyclic axial and torsional loading in internal rotation, with monitoring by means of optical motion tracking. Results. Initial axial stiffness and torsional stiffness in internal and external rotation for straight double plating (548.1 ± 134.2 N/mm, 2.69 ± 0.52 Nm/° and 2.69 ± 0.50 Nm/°) was significantly higher versus helical double plating (442.9 ± 133.7 N/mm, 2.07 ± 0.32 Nm/° and 2.16 ± 0.22 Nm/°), p≤0.04. Initial interfragmentary axial displacement and flexural rotation under 500 N static loading were significantly smaller for straight plating (0.11 ± 0.14 mm and 0.21 ± 0.10°) versus helical plating (0.31 ± 0.14 mm and 0.68 ± 0.16°), p<0.01. However, initial varus deformation under this loading remained not significantly different between the two fixation methods (straight: 0.57 ± 0.23°, helical: 0.75 ± 0.34°), p=0.08. During dynamic loading, within the course of the first 4000 cycles the movements of the distal fragment in flexion were significantly bigger for helical over straight plating (1.03 ± 0.33° versus 0.40 ± 0.20°), p<0.01. However, no significant differences were observed between the two fixation methods in terms of varus, internal rotation, axial and shear displacements at the fracture site, and number of cycles to failure. Conclusions. Augmented lateral plating of unstable distal femoral fractures with use of supplemental helically shaped medial plate was associated with more elastic bone-implant construct behavior under static and dynamic loading compared to straight double plating. Both fixation methods resulted in comparable number of cycles to failure. From a biomechanical perspective, the more elastic helical double plating may be considered as useful alternative to straight plating, potentially reducing stress risers at the distal bone-implant interface due to its ameliorated damping capacities

Literature suggests that joint orthopaedic and geriatric care, and geriatric orthopaedic rehabilitation units, would provide best care for fractured neck of femur (NOF) patients. These are often elderly frail patients with concurrent illnesses and co-morbidities who also have a fracture. There is to date no quantitative data. This completed audit quantifies the care provided on the orthopaedic wards in the first phase solely by orthopaedic team, and in the repeat phase with additional regular geriatric input from an orthogeriatric senior house officer (SHO) and consultant geriatrician ward rounds. A retrospective audit of fractured NOF patients admitted to acute orthopaedic wards under orthopaedics and treated operatively. The first phase analysed 72 patients with sole orthopaedic care. The repeat phase analysed 25 patients after the introduction of an orthogeriatric SHO and geriatric ward rounds. The first audit phase of orthopaedic care alone found that 50% of patients were reviewed each day of the first post op seven-day week. The mean number of reviews in the post-op week was three. A total of 58% patients were operated on the next day. A minority never had post-op bloods or x-rays prior to discharge from the acute bed. Ad hoc medical input by referral occurred in 50% of patients. The repeat audit of combined orthogeriatric care found that 75% of patients were reviewed each day in the post-op week. The mean number of reviews in the post-op week rose to five. Similar to the first phase, 59% proceeded to next day surgery with combined care. All patients had timely bloods and x-rays before discharge from the acute bed. Medical input rose to 80% due to regular ward rounds, and ad hoc referrals decreased in quantity whilst increased in quality. Length of stay and mortality were reduced. The clinical risk of fractured NOF patients was reduced on the appointment of an orthogeriatric SHO in combination with formal reviews by consultant geriatrician. Further models of care are being evaluated. This audit adds evidence that joint care is better for these usually elderly and co-morbid patients

Worldwide, it is expected that 6.3 million patients will sustain a hip fracture in 2050. Hemiarthroplasty is commonly practiced for displaced femoral neck fractures. The choice between unipolar (UH) or bipolar (BH) hemiarthroplasty is still controversial. The objective of this study was to assess the effect on hip function of BH compared to UH for a displaced femoral neck fracture in elderly patients. We conducted a systematic review and meta-analysis of randomized controlled trials comparing BH to UH. Data sources were Medline, Embase, Cochrane Library and Web of Science. All data was pooled in Review Manager (RevMan) version 5.3 software. Selection of the studies included, data abstraction, data synthesis, risk of biais and quality of evidence evaluation was done independently by two authors. Our primary outcome was postoperative hip function. Secondary outcomes were health-related quality of life (HRQoL), acetabular erosion and postoperative complications. 13 randomized controlled trials (n=2256) were eligible for the meta-analysis. There was no difference in hip function scores (standardized mean difference of 0.33 [−0.09–0.75, n=864, I. 2. = 87%,]). Patients with bipolar heads had higher Health-Related Quality of Life scores than patients with unipolar heads (mean difference in EQ-5D scores of 0.12 [0.04–0.19, n=550, I. 2. = 44%]). The use of BH decreased the incidence of acetabular erosion (relative risk of 0.37 [0.17–0.83, n=525, I. 2. = 0%]). There was no relative risk difference for mortality, dislocation, revision and infection. Due to the high heterogeneity between the studies included, it is still unclear whether patients undergoing BH have better hip function than patients undergoing UH. Although, health-related quality of life (HRQoL) may be improved. Future research could be conducted to determine whether a BH offers a better quality of life than UH to geriatric patients undergoing surgery. More precise assessment scores could be developed to better evaluate postoperative outcomes

Introduction. While interdisciplinary protocols and expedited surgical treatment improve management of geriatric hip fractures, the impact of such interventions on patients undergoing specifically arthroplasty for femoral neck fracture (FNF) has not been well studied. The aim of this study is to evaluate the efficacy of an interdisciplinary hip fracture protocol for patients undergoing arthroplasty for acute FNF. Methods. In 2017, our tertiary care institution implemented a standardized interdisciplinary hip fracture protocol. We conducted a retrospective review of adult patients who underwent hemiarthroplasty (HA) or total hip arthroplasty (THA) for FNF from July 2012 – March 2020, and compared patient characteristics, hospitalization characteristics, and outcomes between those treated before and after protocol implementation. Results. 157 patients were treated before implementation (22.3% THA), and 114 patients were treated after implementation (32.5% THA). Demographics and medical comorbidities were similar before and after protocol implementation. Patients who underwent HA were older (82.1 vs 71.1 years, p<0.001), more medically complex (Charlson Comorbidity Index 6.4 vs 4.1, p<0.001), and more likely to develop delirium (8.5% vs 0%, p=0.024) than those who underwent THA. Patients treated after implementation had reduced time between admission and operative management (24.1 vs 46.5 hours, p=0.042), decreased rate of major complications (0% vs 12.7%, p<0.001), decreased hospital length of stay (LOS) (5.2 vs 6.4 days, p=0.008), increased rate of discharge to home (26.3% vs 14.7%, p=0.03), and decreased 365-day mortality (14.6% vs 26.1%, p=0.049). There were no significant differences between post-protocol and pre-protocol, respectively, 90-day readmission (18.2% vs 21.7%, p=0.53) or 30-day mortality (3.7% vs 5.1%, p=1.0). Conclusion. This interdisciplinary protocol reduced time to operative management, hospital LOS, in-hospital complications, and one-year mortality for patients who underwent arthroplasty for FNF, without increasing readmission or non-home discharge. Such interventions are critical in improving outcomes and reducing costs for an aging population

Collection of new data for the Scottish hip fracture audit stopped in December 2008. The proposed standard of operating on 98% of all hip fractures within 24 hours of admission, subject to medical fitness and during safe operating hours should now be maintained. Methods. We prospectively collected data from 102 consecutive hip fracture patients documenting the patient's journey from admission to discharge from the orthopaedic ward to look at whether the standard had been maintained. Results. 50% of patients get to theatre 24hrs or earlier with 60% catheterised perioperatively.50% of patients were moved from the acute orthopaedic facility at a week with less than 20% of these getting back to their usual place of residence. 25% were still on the acute ward at two weeks and 3% died in the immediate post operative period. However, the number of co-morbidities did not seem to correlate with time to discharge. The majority of patients transferred to onward care moved to the geriatric rehabilitation ward within the hospital. Prioritisation of hip fracture patients on the trauma list needs to be continued along with improvements in the availability of rehabilitation beds. Pre-operative medical work up for patients with reversible illness and post-operative geriatric care will improve the outcomes for these frail patients

Introduction. Patients-reported outcome measures (PROMs) have been reported as the important methods to evaluate clinical outcomes in total knee arthroplasty (TKA). The patient satisfaction score in Knee Society Score (KSS-2011) has been used in the recent literatures. Patient satisfaction was subjective parameter, and would be affected by multiple factors including psychological factors and physical conditions at not only affected joint but also elsewhere in the body. The question was raised regarding the consistency of patient satisfaction score in KSS-2011 to other PROMs. The purpose of this study was to investigate the correlation of patient satisfaction in KSS-2011 to other categories in KSS-2011 and to other PROMs including Forgotten Joint Score (FJS-12), EuroQol-5 Dimensions (EQ-5D) and 25-questions in Geriatric Locomotive Function Scale (GLFS-25). Material & Method. 83 patients over 65 years old with osteoarthritic knees were involved in this study. All patients underwent CR-TKAs (Persona CR. R. ). The means and ranges of demographics were as follows: age; 74.5 years old (65–89), Hip-Knee-Ankle (HKA) angle; 12.4 (−6.2–22.5) in varus. We asked patients to fulfill the questionnaire including KSS-2011, FJS-12, EQ-5D and GLFS-25 at 1-year postoperative follow-up visit. KSS-2011 consisted of 4 categories of questions; patient satisfaction (PS), symptoms, patient expectations (PE), functional activities (FA). We evaluated the correlation of PS to other PROMs using simple linear regression analyses (p<0.001). Results. The means and standard deviations of 1-year postoperative scores were as follows: PS; 28.5 ± 7.0, symptoms; 19.1 ± 4.3, PE; 11.2 ± 2.9, FA; 71.5 ± 16.6, FJS-12; 51.5 ± 18.6, EQ5D; 0.69 ± 0.10, GLFS-25; 25.7 ± 16.9. PSs were moderately positively correlated to other categories in KSS-2011(correlation coefficient (r): symptoms; 0.69, PE; 0.73, FA; 0.69). PSs were positively correlated to both FJS-12 and EQ5D (r: FJS-12; 0.72, EQ-5D; 0.67) and negatively correlated to GLFS-25(r; −0.74). Discussions. Patient satisfaction score positively correlated to the symptoms, patient expectation and functional activities in KSS-2011 with moderately high correlation coefficient. This meant the better pain relief and functional outcome improved patient satisfaction. Although there had be reported preoperative higher expectation would lead to poor patient satisfaction postoperatively, we interestingly found positive correlation between patient satisfaction and expectation at 1 year after TKA. Patient with the higher satisfaction tended to expect more in the future, on the other hand, unsatisfied patient with residual pain and/or poor function would resign themselves to the present status and reduced their expectation in our patient population. We have found patient satisfaction score in KSS-2011 significantly correlated to FJS-12 and GLFS-25 with strong correlation coefficient. This meant patient satisfaction could be considered consist to other PROMS in relatively younger patient with better functional status in this study. Conclusion. The patient satisfaction score in KSS-2011 was found to be consistent with moderately high correlations coefficient to other categories in KSS-2011 and other PROMs including FJS-12, EQ-5D, GLFS-25 at 1 year after (CR)-TKA.

The February 2024 Hip & Pelvis Roundup³⁶⁰ looks at: Trial of vancomycin and cefazolin as surgical prophylaxis in arthroplasty; Is preoperative posterior femoral neck tilt a risk factor for fixation failure? Cemented versus uncemented hemiarthroplasty for displaced intracapsular fractures of the hip; Periprosthetic fractures in larger hydroxyapatite-coated stems: are collared stems a better alternative for total hip arthroplasty?; Postoperative periprosthetic fracture following hip arthroplasty with a polished taper slip versus composite beam stem; Is oral tranexamic acid as good as intravenous?; Stem design and the risk of early periprosthetic femur fractures following THA in elderly patients; Does powered femoral broaching compromise patient safety in total hip arthroplasty?

Introduction: Less invasive surgical technique in THA is expected to minimize soft tissue damage and expedite rehabilitation. Due to this, it is now in widespread use in elective THA. The large geriatric patient population suffering a fractured neck of femur thereby would also benefit of this technique. Aim of this study was to evaluate if this technique is feasible in the non-elective setting of geriatric patients and if there are benefits regarding clinical and social outcome. Patients and Methods: Study setup is a prospective randomized trial with a positive Ethical Committee vote. Included were patients under legal care of a third party. Inclusion criteria were the indication for bipolar hip arthroplasty including grade ASA 4; exclusion criteria included neoplastic disease and rheumatoid arthritis. Setting is a large university hospital. After biometrical evaluation, each arm was set as 30 patients. Primary end point was the modified Barthel index. 48 patients were female. Mean age for female patients was 85.5, for male 82.9 years. There was no detectable difference in the groups regarding age, sex and BMI. As a less invasive approach, the well described „Direct Anterior Approach-DAA”(modified Smith-Petersen approach) was chosen. In the other arm the Watson-Jones approach was used. The ABG II stem with a bipolar UHR head (Stryker) were used in both groups. To minimize the learning curve, 10 cadaver- and 15 clinical procedures were performed with the DAA approach before the study. The pre- and postoperative regimen was identical in both arms. The modified Barthel index and other clinical parameter were determined preoperatively and at 4 postoperative intervals up to 40 days. Results: There were no statistical differences between both groups for intra- and postoperative complications. The mean theatre time was 4.8 minutes longer for the DAA group, in the first 10 patients this difference was measured with 16 minutes. The Barthel Index was only statistically different at 40 days, at this time the DAA patients had reached their preoperative mobility level whilst the conventional approach patients (with a pre-operative level of 42.5) were measured with 25 points. The hemoglobin levels on day 5 and 16 were significantly different with a higher Hb for the DAA group. All other parameters showed no significant difference. Conclusion: The DAA approach has a clear learning curve. Once this has passed, the theatre time is only slightly longer. There is a detectable benefit regarding early rehabilitation and a slight but significantly reduced blood loss

Osteoporosis is common in elderly patients and is commonly associated with fractures of the neck of the femur. It is known that this condition is not treated optimally by orthopaedic services around the world. We aim to examine the level of osteoporosis treatment in this fracture and how effective we were in improving treatment for osteoporosis. We retrospectively examined hospital documents from patients admitted between 1 January and 31 December 2004 with femoral neck fracture. All notes were retrieved and were complete. We examined the medications on admission, the place of residence, place of discharge, frequency of DEXA scanning and medications. One hundred and twenty patients were admitted with fracture of the neck of the femur. This group consisted of 23 males with an average age of 76.7, 97 females with an average age of 83.7. Seventy five of these patients were admitted from home, 45 from a rest home. Four patients died prior to treatment, one refused treatment and subsequently died in a hospice. Osteoporotic medications on admission showed that 13 patients were on Bisphosphonate, 6 on Vitamin D and twelve on calcium supplements. Only 14 patients had had DEXA scans prior to admission. On admission eight patients were on no medications of any sort, 53 were on 1–4 medications, 53 were on 5–9 medications and 6 were on greater than 10 medications. On discharge from orthopaedic of the 120 patients 13 were on Bisphosphonate, six on Vitamin D, 13 on calcium supplements. Six patients were on no medications, 47 on 1–4 medications, 55 on 5–9 medications, nine on greater than 10 medications. On discharge from geriatric service, to which 69 patients had been referred 25 were on Bisphosphonate, 13 on Vitamin D, 18 on calcium supplements. One patient was on no medication. 20 were on 1–4 medications, 41 on 5–9 medications and seven on greater than 10 medications. Fifty four had had DEXA scans. We found that the rate of treatment of osteoporosis in the community remains poor with no improvement while in the orthopaedic service. On discharge from the geriatric service significant improvement in osteoporotic medication occurred but there was also an increased in polypharmacy. Further work on the investigation and treatment of osteoporosis in this country is required

Introduction. Despite the demonstrated success of total knee arthroplasty (TKA) and higher rates of arthritis and disability from arthritis among minorities, these populations utilize TKA at lower rates than non-Hispanic white patients in the United States. In addition, women present for TKA with more advanced disease prior to TKA than their male counterparts. In order to explore potential reasons for this, we examined the relationship between race, gender, and pre-operative expectations on postoperative outcomes among patients undergoing TKA. Methods. 134 patients scheduled for primary unilateral TKA secondary to moderate to severe osteoarthritis were enrolled in this two-institution prospective study. All patient demographics were collected and recorded in an electronic data registry. In addition, patient reported outcome (PRO) questionnaires, including the Knee Injury and Osteoarthritis Outcome Score (KOOS), HSS Patient Expectation Questionnaire, Social Support Survey, Pain Catastrophizing Scale, Visual Analogue Pain Scale (VAS), Geriatric Depression Scale and European Quality (EQ) of Life 5-Dimensions with EQ VAS were prospectively collected at 4 time points (baseline, 4–8 weeks, 9–14 months, 20–26 months postoperative). Statistical analysis was then conducted among patients of different gender and ethnic background to assess for the effect of these demographic variables on patient expectations and outcomes. Results. Female sex was associated with worse preoperative KOOS scores in symptoms (p=0.021), pain (p=0.019), and activities of daily living (p=0.020). African American race was associated with worse preoperative KOOS scores in pain (p=0.009), activities of daily living (ADLs) (p=0.004), and quality of life (QOL) (p=0.003). However, despite worse pre-operative scores, no statistically significant differences were noted in the aforementioned categories between the groups at any point post-operatively. Conclusion. Our results indicate that female and African American patients undergoing TKA presented with worse pre-operative KOOS scores compared with white male patients. However, outcomes were good among all groups postoperatively, and neither race nor gender was associated with compromised post-operative outcomes in relation to pain, ADLs or QOL. These findings may be valuable in counseling patients and surgeons regarding the value of increase utilization of TKA in these patient populations. Further study is necessary to better understand the lower utilization or later presentation observed in these populations

Aims

The aim of this study was to explore current use of the Global Fragility Fracture Network (FFN) Minimum Common Dataset (MCD) within established national hip fracture registries, and to propose a revised MCD to enable international benchmarking for hip fracture care.

Introduction. Aged trauma patients with proximal femur fractures are prone to various complications. They may be associated with their comorbidities which also need to be adressed. These complications limit the patient”s postoperative health status and subsequently their activity and independency. As an attempt to improve the postoperative management of aged hip fracture patients a better understanding of the postoperative condition in these patients is necessary. Therefore, this meta-analysis is intended to provide an overview of postoperative complications in the elderly hip fracture patients and to improve the understanding of an adequate postoperative management. Material and method. Medline was used to screen for studies reporting on the complication rates of hip fracture patients > 65 years. The search criteria were: “proximal femur fracture, elderly, complication”. In addition to surgical studies, internal medicine and geriatric studies were also included. Randomized studies, retrospective studies as well as observation studies were included. Furthermore, reoperation rates as well as treatment-related complications were recorded. The 1-year mortality was calculated as outcome parameter. Results. Overall 54 studies were enrolled, published between 2011 and 2016. The mean age of the 9812 patients was 81 years (65–99 years). Follow-up was at least one year. The reoperation rate after osteosynthesis of pertrochanteric femur fractures was 8.7%. The reoperation rate was dependent on the type of fracture and the surgical method. Pneumonia (9,5%) and urinary tract infections (27%) were the most common postoperative infections. With 23%, delirium was one of the most common medical complications. The 1-year mortality rate was 18.7%. Conclusion. Orthogeriatric patients represent a complex patient population. Addressing the special needs of elderly patients reduces postoperative complications. Establishing comanagement or orthogeriatric wards can also be helpful to manage comorbidities and postoperative complications. It is important to not only choose the proper surgical procedure but to monitor orthogeriatric patients closely during their hospitalization

Background. Polypharmacy of elderly trauma patients entails further difficulties in addition to the fracture treatment. Impaired renal function, altered metabolism and drugs that are potentially delirious or inhibit ossification, are only a few examples which must be carefully considered for the medication in elderly patients. The aim of this study was to investigate, if medication errors could be prevented by orthogeriatric comanagement compared to conventional trauma treatment. Material and methods. In a superregional traumacenter based on two locations in Munich, all patients ≥ 70 years with proximal femur fracture were consecutively recorded in a period of 3 months. After the end of the treatment the medical records of each patient were analyzed. At the hospital location 1 the treatment was carried out without orthogeriatric comanagement, at the hospital location 2 with this concept (DGU-certified orthogeriatric center). In addition to the basic medication all newly added drugs were recorded as well as changes in the medication plan and also wether treatment was carried out by the geriatrician or the trauma surgeon. Based on the START / STOPP criteria for the medication of geriatric patients, we defined “no-go” drugs with the geriatrician of the orthogeriatric center which should be avoided in the orthogeriatric patient (including benzodiazepines, gyrase inhibitors, NSAID like Ibuprofen with impaired GFR). The statistical analysis was done with the chi-square-test (IBM SPSS Statistics 24). Results and conclusion. A total of 46 patients were included, 37 of them female and 9 male with an average age of 84,5 years (SD±6.8). At the location without a geriatrician (18 patients), a prescription of one or more “no-go” drugs was found in 9 patients, whereas in location 2 (28 patients) only in 3 patients (p=0.003). Besides that, at the location with the geriatrician, a change in the medication was made for 17 patients during their stay in hospital. This shows that with the fixed integration of the geriatrician into the trauma surgical team, errors in the medication of the patients could be significantly more frequent avoided or faster detected and corrected. Although this should not limit the responsibility of the rest of the team, there is no doubt about the importance of the interdisciplinary treatment of elderly trauma patients

The April 2024 Trauma Roundup³⁶⁰ looks at: The infra-acetabular screw in acetabular fracture surgery; Is skin traction helpful in patients with intertrochanteric hip fractures?; Reducing pain and improving function following hip fracture surgery; Are postoperative splints helpful following ankle fracture fixation?; Biomechanics of internal fixation in Hoffa fractures: a comparison of four different constructs; Dual-plate fixation of periprosthetic distal femur fractures; Do direct oral anticoagulants necessarily mean a delay to hip fracture surgery?; Plate or retrograde nail for low distal femur fractures?.

Aims

To describe the epidemiology of acetabular fractures including patient characteristics, injury mechanisms, fracture patterns, treatment, and mortality.

Aims

Posterior column plating through the single anterior approach reduces the morbidity in acetabular fractures that require stabilization of both the columns. The aim of this study is to assess the effectiveness of posterior column plating through the anterior intrapelvic approach (AIP) in the management of acetabular fractures.

Aims

Hip fractures are a major cause of morbidity and mortality, and malnutrition is a crucial determinant of these outcomes. This meta-analysis aims to determine whether oral nutritional supplementation (ONS) improves postoperative outcomes in older patients with a hip fracture.

Aims

Proximal humeral fractures are the third most common fracture among the elderly. Complications associated with fixation include screw perforation, varus collapse, and avascular necrosis of the humeral head. To address these challenges, various augmentation techniques to increase medial column support have been developed. There are currently no recent studies that definitively establish the superiority of augmented fixation over non-augmented implants in the surgical treatment of proximal humeral fractures. The aim of this systematic review and meta-analysis was to compare the outcomes of patients who underwent locking-plate fixation with cement augmentation or bone-graft augmentation versus those who underwent locking-plate fixation without augmentation for proximal humeral fractures.

Aims

Endoprosthetic reconstruction with a distal femoral arthroplasty (DFA) can be used to treat distal femoral bone loss from oncological and non-oncological causes. This study reports the short-term implant survivorship, complications, and risk factors for patients who underwent DFA for non-neoplastic indications.

With around 20–40% of our bodyweight, skeletal muscles are the biggest organ complex of the human body. Being a metabolic active tissue, muscle mass, function and fibertype composition is highly regulated in a tight spatial-temporal manner. In geriatric patients, it is essentially important to understand the underlying mechanisms of the age related losses of fiber size and total number of fibers, as well as fibertype shifting. To date, there have been few studies dealing with gene expression profiling of skeletal muscles, mostly focusing on age related differences in whole-muscle specimen. Being carried out on mouse or rat limb muscles, most other studies do not represent the conditions of human muscle, due to the differences in fibertype composition. Our study provides a fibertype-specific approach for whole-genome expression analysis in human skeletal muscle. 22 fresh frozen biceps brachii and quadriceps femoris muscle samples were acquired from the muscle bank of the Friedrich-Baur-Institut, Department of Neurology, Ludwig-Maximilians-University, Munich, Germany. Consecutive cross-sections were used for immunohistochemical myosine-heavy-chain-staining and individual fibers were acquired by laser-capture-microdissection. Around 100 cells of each fibertype of each biopsy were dissected, reversely transcribed, pre-amplified and labeled for microarray analysis. Fiber type-specific gene expression was analyzed with ANOVA. Correction for multiple testing was performed using the Benjamini-Hochberg procedure with a conservative threshold and the pathway analysis was carried out using the Ingenuity Pathway Analysis program (QIAGEN). By comparing type I vs. type IIa, type I vs. type IIx and type IIa vs. type IIx, we could identify 2855, 2865 and 510 differentially expressed genes. As expected, many differentially regulated genes belong to functional groups like cytoskeleton, muscle contraction and energy metabolism, proving the feasibility of our study. However, many genes that are involved in the response to oxidative stress were also differently regulated, showing distinct mechanisms of the different fiber types, of coping with oxidative stress. In consensus with available literature, the relative proportion of type I fibers seemed to increase with age. Despite higher levels of oxidative stress, type I fibers seem to have more efficient antioxidative mechanisms in comparison to type IIa and IIx fibers, which might explain the higher vulnerability of members of the type II family to oxidative stress. Furthermore, genes that are involved in fibertype specification were also regulated differently. However, we could not verify an age-specific activation of pathways involved in fibertype shifting. Whether fibertype shifting is solely due to disproportionate loss of type II fibers, or also in vivo - transdifferentiation of fibers, has to be investigated further

Abstract. In aged trauma patients the basic prerequisite is early mobilization and full weight-bearing, as immobilization can trigger various complications such as pressure ulcers, pneumonia, urinary tract infections and others. Mortality of elderly patients increases significantly in fracture patients with partial weight-bearing compared to populations with total weight-bearing. Besides the limited physical strength in these patients, partial-weight bearing is however frequently used for the aftercare of hip fracture patients. Therefore, the present study aims to evaluate mobility of aged hip fracture patients with regards to weight-bearing and postoperative mobility. Methods. An insole mobile force sensor was used to measure the post-operative weight-bearing by assessing the compressive forces between foot and shoe. Only patients (n=15) that suffered a trochanteric fracture >75 years of age were included and compared to a study group of patients (n=18) with fractures of the lower limb <40 years of age. Patients with cognitive disorders such as delirium and other diseases limiting the realization of partial weight-bearing were excluded. Both groups were instructed to maintain partial weight bearing of the affected limb following surgery. Following five days of training by our department of physiotherapy, the patients were requested to perform a gait analysis with the insole mobile force sensor. During gait analysis the maximum load was measured (kg) and the time over which the partial load could be maintained was determined. Results. None of the aged patients in the test group could meet the partial load at all times. 73.33% of patients (11 out of 15) exceeded the specified load by more than twice (> 40 kg). In the control group, 55.56% (10 of 18) of the patients were able to meet the partial load. A further 22.22% of the young patients (4 out of 18) were able to exceed only slightly (<120%, <24 kg). It was also shown that only 11.11% (2 of 18) put more than double of the allowed weight (> 40 kg) on the affected leg in the younger group. Only one of the aged patients was able to exceed the pre-determined weight-bearing restrictions for less than 10% of the measured time. In comparison, significantly more patients in the control group (88,89%; 16 of 18; p<0,05) were able to maintain the partial load for more than 90.0% of the time of gait analysis. Conclusion. Elderly patients seem to be unable to follow partial weight-bearing restrictions as proven in the present trial. As early mobilization of geriatric trauma patients is an important element for a successful rehabilitation, the relict of postoperative partial weight-bearing in these patients should be abandoned. Thus, the surgical therapy should allow immediate full weight bearing following surgery of aged hip fracture patients

Introduction. The incidence of distal femoral fractures in the geriatric population is growing and represents the second most common insufficiency fracture of the femur following fractures around the hip joint. Fixation of fractures in patients with poor bone stock and early mobilisation in feeble and polymorbide patients is challenging. Development of a fixation approach for augmentation of conventional LISS (less invasive stabilization system) plating may result in superior long-term clinical outcomes and enhance safe weight bearing. Objectives. The aim of this study was to investigate the biomechanical competence of two different techniques of augmented LISS plating for treatment of osteoporotic fractures of the distal femur in comparison to conventional LISS plating. Materials & methods. Unstable distal femoral fracture AO/OTA 33-A3 was set in artificial femora with low density simulating osteoporotic bone. Three study groups, consisting of 10 specimens each, were created for instrumentation with a 9-hole LISS plate, a LISS plate with an additional 3D-printed polyactide cylindrical intramedullary graft, as well as a LISS plate plus a medial 3.5mm LCP (locking compression plate) - double plating. All specimens were non-destructively tested under axial (20–150N) and torsional (0–4Nm) quasi-static loading. Each construct was tested with two different working length (WL) configurations (long and short) of the LISS plate. Relative movements between the most medial superior and inferior osteotomy aspects were investigated via three-dimensional motion tracking analysis. Results. Interfragmentary displacement along the femur axis (mm) under 150N axial loading was 2.03±0.23/1.65±0.27 for LISS with long/short WL, 0.18±0.06/0.18±0.04 for double plating with long/short WL, and 0.40±0.05/0.30±0.05 for LISS plus graft with long/short WL. Shear interfragmentary displacement (mm) under 4Nm torsional loading in internal rotation was 1.16±0.17/0.92±0.11 for LISS with long/short WL, 0.40±0.10/0.43±0.07 for double plating with long/short WL, and 1.09±0.13/0.82±0.11 for LISS plus graft with long/short WL. Double plating revealed significantly smaller longitudinal and shear displacement compared to the other two techniques for long and short WL, respectively (P≤0.010). In addition, LISS plus graft fixation was with significantly less longitudinal displacement in comparison to conventional LISS plating for long and short WL, respectively (P≤0.001). Long WL resulted in significantly higher longitudinal and shear displacement compared to short WL for LISS and LISS plus graft (P≤0.032), but not for double plating (P=1.000). Conclusion. Intramedullary grafting resulted in significantly increased fracture stability under axial loading in comparison to conventional LISS plating. However, it was not efficient enough to achieve comparable stability to double plating

Musculoskeletal diseases are having a growing impact worldwide. It is therefore crucial to have an evidence base to most effectively and efficiently implement future health services across different healthcare systems. International trials are an opportunity to address these challenges and have many potential benefits. They are, however, complex to set up and deliver, which may impact on the efficient and timely delivery of a project. There are a number of models of how international trials are currently being delivered across a range of orthopaedic patient populations, which are discussed here. The examples given highlight that the key to overcoming these challenges is the development of trusted and equal partnerships with collaborators in each country. International trials have the potential to address a global burden of disease, and in turn optimize the benefit to patients in the collaborating countries and those with similar health services and care systems.

Aims

The aim of this study was to describe the current pathways of care for patients with a fracture of the hip in five low- and middle-income countries (LMIC) in South Asia (Nepal and Sri Lanka) and Southeast Asia (Malaysia, Thailand, and the Philippines).

We aim to explore the potential technologies for monitoring and assessment of patients undergoing arthroplasty by examining selected literature focusing on the technology currently available and reflecting on possible future development and application. The reviewed literature indicates a large variety of different hardware and software, widely available and used in a limited manner, to assess patients’ performance. There are extensive opportunities to enhance and integrate the systems which are already in existence to develop patient-specific pathways for rehabilitation.

The April 2023 Hip & Pelvis Roundup³⁶⁰ looks at: Do technical errors determine outcomes of operatively managed femoral neck fractures in younger adults?; Single-stage or two-stage revision for hip prosthetic joint infection (INFORM); Fixation better than revision in type B periprosthetic fractures of taper slip stems; Can you maximize femoral head size at the expense of liner thickness?; Plasma D-dimer for periprosthetic joint infection?; How important is in vivo oxidation?; Total hip arthroplasty for HIV patients with osteonecrosis.

Aims

Dual-mobility acetabular components (DMCs) have improved total hip arthroplasty (THA) stability in femoral neck fractures (FNFs). In osteoarthritis, the direct anterior approach (DAA) has been promoted for improving early functional results compared with the posterolateral approach (PLA). The aim of this study was to compare these two approaches in FNF using DMC-THA.

The August 2023 Hip & Pelvis Roundup³⁶⁰ looks at: Using machine learning to predict venous thromboembolism and major bleeding events following total joint arthroplasty; Antibiotic length in revision total hip arthroplasty; Preoperative colonization and worse outcomes; Short stem cemented total hip arthroplasty; What are the outcomes of one- versus two-stage revisions in the UK?; To cement or not to cement? The best approach in hemiarthroplasty; Similar re-revisions in cemented and cementless femoral revisions for periprosthetic femoral fractures in total hip arthroplasty; Are hip precautions still needed?

Aims

Weightbearing instructions after musculoskeletal injury or orthopaedic surgery are a key aspect of the rehabilitation pathway and prescription. The terminology used to describe the weightbearing status of the patient is variable; many different terms are used, and there is recognition and evidence that the lack of standardized terminology contributes to confusion in practice.

The June 2024 Knee Roundup³⁶⁰ looks at: The estimated lifetime risk of revision after primary knee arthroplasty influenced by age, sex, and indication; Should high-risk patients seek out care from high-volume surgeons?; Stability and fracture rates in medial unicondylar knee arthroplasties; Rethinking antibiotic prophylaxis for dental procedures post-arthroplasty; Evaluating DAIR: a viable alternative for acute periprosthetic joint infection; The characteristics and predictors of mortality in periprosthetic fractures around the knee; Patient health-related quality of life deteriorates significantly while waiting six to 12 months for total hip or knee arthroplasty; The importance of looking for diversity in knee implants.

Aims

The aims of this study were to assess quality of life after hip fractures, to characterize respondents to patient-reported outcome measures (PROMs), and to describe the recovery trajectory of hip fracture patients.

Aims

To identify variables independently associated with same-day discharge (SDD) of patients following revision total knee arthroplasty (rTKA) and to develop machine learning algorithms to predict suitable candidates for outpatient rTKA.

Aims

Periprosthetic proximal femoral fractures (PFFs) are a major complication after total hip arthroplasty (THA). Health status after PFF is not specifically investigated. The aim of this study is to evaluate the health status pattern over two years after sustaining a PFF.

Aims

Despite limited clinical scientific backing, an additional trochanteric stabilizing plate (TSP) has been advocated when treating unstable trochanteric fractures with a sliding hip screw (SHS). We aimed to explore whether the TSP would result in less post operative fracture motion, compared to SHS alone.

Aims

The use of multimodal non-opioid analgesia in hip fractures, specifically acetaminophen combined with non-steroidal anti-inflammatory drugs (NSAIDs), has been increasing. However, the effectiveness and safety of this approach remain unclear. This study aimed to compare postoperative outcomes among patients with hip fractures who preoperatively received either acetaminophen combined with NSAIDs, NSAIDs alone, or acetaminophen alone.

Aims

Patients with proximal femoral fractures (PFFs) are often multimorbid, thus unplanned readmissions following surgery are common. We therefore aimed to analyze 30-day and one-year readmission rates, reasons for, and factors associated with, readmission risk in a cohort of patients with surgically treated PFFs across Austria.

Aims

This study assessed the impact of COVID-19 on hip and distal femur fracture patient outcomes across three successive UK lockdown periods over one year.

Despite being one of the most common injuries around the elbow, the optimal treatment of olecranon fractures is far from established and stimulates debate among both general orthopaedic trauma surgeons and upper limb specialists. It is almost universally accepted that stable non-displaced fractures can be safely treated nonoperatively with minimal specialist input. Internal fixation is recommended for the vast majority of displaced fractures, with a range of techniques and implants to choose from. However, there is concern regarding the complication rates, largely related to symptomatic metalwork resulting in high rates of implant removal. As the number of elderly patients sustaining these injuries increases, we are becoming more aware of the issues associated with fixation in osteoporotic bone and the often fragile soft-tissue envelope in this group. Given this, there is evidence to support an increasing role for nonoperative management in this high-risk demographic group, even in those presenting with displaced and/or multifragmentary fracture patterns. This review summarizes the available literature to date, focusing predominantly on the management techniques and available implants for stable fractures of the olecranon. It also offers some insights into the potential avenues for future research, in the hope of addressing some of the pertinent questions that remain unanswered.

Aims

Evidence exists of a consistent decline in the value and time that medical schools place upon their undergraduate orthopaedic placements. This limited exposure to trauma and orthopaedics (T&O) during medical school will be the only experience in the speciality for the majority of doctors. This review aims to provide an overview of undergraduate orthopaedic training in the UK.

Aims

This study aimed to identify risk factors (patient, healthcare system, and socioeconomic) for mortality after hip fractures and estimate their relative importance. Further, we aimed to elucidate mortality and survival patterns following fractures and the duration of excess mortality.

Aims

While interdisciplinary protocols and expedited surgical treatment improve the management of hip fractures in the elderly, the impact of such interventions on patients specifically undergoing arthroplasty for a femoral neck fracture is not clear. We sought to evaluate the efficacy of an interdisciplinary protocol for the management of patients with a femoral neck fracture who are treated with an arthroplasty.

Aims

The aim of this study was to determine the impact of hospital-level service characteristics on hip fracture outcomes and quality of care processes measures.

Acetabular fractures, particularly in the geriatric population are on the rise. A recent study indicated a 2.4-fold increase in the incidence of acetabular fractures, with the fastest rising age group, those older than the age of 55. Controversy exists as to the role and indications for total hip arthroplasty (THA), particularly in the acute setting. Three common scenarios require further evaluation and will be addressed. 1.) What is the role of THA in the acute setting for young patients (< 55 years old)? 2.) What is the role and indications for THA in the older patient population (>55 years) and what are surgical tips to address these complex issues? 3.) What are the outcomes of THA in patients with prior acetabular fractures converted to THA?. Acetabular fractures in young patients are often the result of high energy trauma and are a life changing event. In general, preservation of the native hip joint and avoidance of arthroplasty as the first line treatment should be recommended. A recent long-term outcome study of 810 acetabular fractures treated with Open Reduction and Internal Fixation (ORIF) demonstrated 79% survivorship at 20 years with need for conversion to THA as the endpoint. Risk factors for failure were older age, degree of initial fracture displacement, incongruence of the acetabular roof and femoral head cartilage lesions. In selected younger patients, certain fracture types with concomitant injuries to articular surfaces may best be treated by acute THA. In the elderly patient population, acetabular fractures are more likely the result of low energy trauma but often times result in more displacement, comminution and damage to the articular surface. Osteoporosis and generalised poor bone quality make adequate reduction and fixation a challenge in these acute injuries. As such, the role of acute arthroplasty is becoming more widespread. Consideration should be given to delayed arthroplasty in certain patients to allow time for fracture healing followed by THA. However, early mobilization and weight bearing is important in the elderly population and consideration should be given to acute THA. The challenge remains gaining appropriate acetabular fixation in the fractured, osteoporotic bone. Early results showed high complication rates with acetabular fixation. However, newer fixation surfaces and advances in ORIF techniques have led to improved results. In addition, the need for complex acetabular reconstruction with the use of cages or cup cage constructs may be required in this setting. Appropriate 3-D imaging is essential to evaluate the extent of involvement of the anterior and posterior columns as well as the acetabular walls. Mears et al. reported on 57 patients who underwent THA for acute acetabular fracture and reported results at a mean of 8.1 years. 79% of patient reported good or excellent results and no acetabular cups were revised for loosening. One of the more common scenarios is the patient that presents with a prior ORIF of an acetabular fracture that has developed post-traumatic arthritis or avascular necrosis of the hip and requires conversion to THA. Challenges in this patient population include dealing with prior hardware that may interfere with THA component fixation, severe stiffness of the joint making exposure difficult and prior heterotopic ossification that may put neurovascular structures at risk. Previous studies have demonstrated lower long-term survivorship of the acetabular component (71% at 20 years) compared to primary THA for osteoarthritis. New acetabular fixation surfaces should mitigate the risk of aseptic loosening in this challenging patient population

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).

Introduction. With the increasing burden of geriatric population in India, TKR is a very common procedure done these days. But as compared to western population the expectations of the people are different in our country. Indian patients want to sit cross legged and squat but can tolerate pain and limp better. So our population has different satisfaction levels after surgery. Keeping this in mind, post op evaluation should also include the performance as well as satisfaction levels. The factors affecting these parameters need to be studied. The current trend is to operate on younger people with more life expectancy and lesser co-morbidities but they have higher demands. Thus it is important to follow TKR patients for an extended time and to study their performance and satisfaction levels and the effect of pre op factors on these parameters. Objectives. To evaluate the patient's satisfaction in terms of postoperative pain and functional outcome. To identify preoperative characteristics predicting the postoperative outcome. MATERIAL AND METHOD. A study was done to analyse the satisfaction level, physical activity and quality of life after one year of TKR surgery using KOOS scoring system and DMC&H General Patient Questionnaire. Clinical data was recorded and a Performa was filled of 104 patients with 152 cemented total knee arthroplasty operated from June 2010 till December 2012 of who consented and underwent surgery at Dayanand Medical College & Hospital Ludhiana (India). Out of these, 56 were unilateral and 48 were bilateral cases. Results. There was a significant improvement in means of all the five KOOS subscale scores but mean difference of the pre op and post op KOOS sports/recreational scores was low as compared to other four subscales. There was no significant effect of sex, duration of symptoms, number of co-morbidities and BMI on post op KOOS outcome scores and patient's satisfaction. Younger age group patients had higher post op KOOS scores but older age group patients had higher post op satisfaction levels. Patients undergoing simultaneous bilateral TKR had higher post op KOOS scores and higher satisfaction levels as compared to patients undergoing unilateral TKR. Patients with higher preop functional and KOOS scores also had better postop satisfaction levels. Mean postoperative KOOS Scores had trend of higher scores in OA patients as compared to RA patients. Post op KOOS pain and ADL scores were comparable to patient's satisfaction level83.7% patients had excellent satisfaction level, 12.5% good, 1.9% fair and 1.9% poor satisfaction one year after surgery. CONCLUSION. Total knee replacement significantly improves patient's pain, symptoms, function and activities of daily living and knee related quality of life. Characters like sex, duration of symptoms, number of co-morbidities and BMI do not significantly affect the outcome. However, preop diagnosis, higher preoperative KOOS score, simultaneous bilateral replacements had possitive effect on postoperative KOOS score and satisfaction levels after 1 year follow up. In younger patients KOOS score improvement was better but satisfaction levels were lower

Acute postoperative periprosthetic joint infection (PJI) is a serious complication after any hemiarthroplasty (HHA) implanted due to a proximal hip fracture. The growing number of chronic institutionalized geriatric patients (CIGP) colonized with multi-drug resistant bacteria (e.g.: MRSA), not covered by usual antibiotic prophylaxis, has been identified as a risk factor for PJI after HHA. We therefore sought to compare the HHA infection characteristics between non-institutionalized patients (NIP) with proximal hip fractures and CIGP. We investigate (1) the rate of compliance with a new proposed protocol, (2) the acute infection rate, 3) the microbiologic characteristics of the infection, and 4) the success of the new protocol. We gathered clinical, operative and infection data on all patients who underwent HHA due to a proximal femoral fracture in our center, during a 3-year period. We focus in the cases of acute postoperative infection (Zimmerli´s criteria). The new proposed antibiotic prophylaxis is cefazolin except in CIGP in which co-trimoxazole is used. During the study period a total of 385 HHA in 385 patients were performed. In all cases the HHA was performed after a proximal femoral fracture. Overall, 109 patients (28,2%) were CIGP. We found an acute postoperative PJI in 21 out 385 HHA procedures, that is, a global acute infection rate of 5.43%. Ten out 109 (9.17%) CIGP patients resulted infected compared to 11 out 278 (3.9%) non-institutionalized patients (p: 0.049). One or more causative microorganisms were identified in 20/21 (95%) of PJI. Globally the Gram-Negative bacilli group accounted for the majority of the infections (60%). Staphylococus aureus was isolated in 3 cases (8.6%) with only a single MRSA infection. The percentage of polymicrobial infections was 47% (10 out of 21). Co-trimoxazole was used in the prophylaxis in 80.1% of the CIGP. In the infected cases a non-effective drug against the microorganism was used in the prophylaxis in 17 (81%) of the acute infected HHA. We confirm that institutionalized patients are more prone to acute infections after a HHA. Our current strategy of antibiotic prophylaxis has showed to be effective in preventing MRSA PJI in CIGP. However, we found an increased rate of infection due to gram-negative bacilli non-covered by the current antibiotic prophylaxis. According our data an extended antibiotic prophylaxis on gram-negative drug will be proposed to be implemented in CIGP scheduled to a HHA because a proximal femoral fracture

Aims

The decrease in the number of satellite cells (SCs), contributing to myofibre formation and reconstitution, and their proliferative capacity, leads to muscle loss, a condition known as sarcopenia. Resistance training can prevent muscle loss; however, the underlying mechanisms of resistance training effects on SCs are not well understood. We therefore conducted a comprehensive transcriptome analysis of SCs in a mouse model.

Background. Growing of the geriatric population has brought about increase of lower extremity fractures. The purpose of this study was to investigate the occurrence of surgical site infection after the surgery for lower extremity fractures, except proximal femoral fracture, in over eighty years old patients. Methods. Patients with closed lower extremity fracture which were treated surgically in 2011 were divided into two groups (Group O; the equal or more than 80 years old, Group Y; from 20 to 65 years old), and the incidence of infection and the outcome after its treatment was compared between Group O and Group Y. Results. In group O, there were 35 fractures in 35 patients with average age of 86.7 years (range from 80 to 92). Five patients (14.3%) showed infection. Only one case recovered from infection, one died because of sepsis and the other three required amputation. The reasons for amputation were advanced sepsis in 2 and severe soft tissue damage in 1. In group Y with 110 fractures in 101 patients, there was no infection (p = 0.0007). Conclusions. The presented study showed that infection rate following lower extremity fracture surgery in group O had been significantly higher than that of group Y. Despite the application of minimum invasive surgery or intramedullary nail, infection occurred in Group O. Once, infection occurred after lower extremity fracture surgery in advanced age patients, it may be difficult to recover the infection without amputation
