Fractures of the distal radius are common, and form a considerable proportion of the trauma workload. We conducted a study to examine the patterns of injury and treatment for adult patients presenting with distal radius fractures to a major trauma centre serving an urban population. We undertook a retrospective cohort study to identify all patients treated at our major trauma centre for a distal radius fracture between 1 June 2018 and 1 May 2021. We reviewed the medical records and imaging for each patient to examine patterns of injury and treatment. We undertook a binomial logistic regression to produce a predictive model for operative fixation or inpatient admission. Overall, 571 fractures of the distal radius were treated at our centre during the study period. A total of 146 (26%) patients required an inpatient admission, and 385 surgical procedures for fractures of the distal radius were recorded between June 2018 and May 2021. The most common mechanism of injury was a fall from a height of one metre or less. Of the total fractures, 59% (n = 337) were treated nonoperatively, and of those patients treated with surgery, locked anterior-plate fixation was the preferred technique (79%; n = 180). The epidemiology of distal radius fractures treated at our major trauma centre replicated the classical bimodal distribution described in the literature. Patient age, open fractures, and fracture classification were factors correlated with the decision to treat the fracture operatively. While most fractures were

Introduction. The management of open long bone fractures is well described and has been standardised through a number of well-established guidelines. However, there is no consensus regarding the application of local antibiotics into the open fracture site as a means of reducing infection rates. Materials & Methods. A systematic review and meta-analysis were undertaken as per PRISMA guidelines. PROSPERO Registration CRD42022323545. PubMed, EMBASE, Scopus and CENTRAL were the databases assessed. The Newcastle Ottawa Scale and the Rob 2 Tool were used to assess bias. A qualitative synthesis of all included studies and meta-analysis of suitable subgroups was undertaken. Results. In total, 12 studies (11 observational, 1 RCT) assessing 2431 open fractures were included for analysis. All compared the addition of a local antibiotic therapy to a standard treatment versus the standard treatment alone. The methods of delivery were vancomycin powder (4 papers), tobramycin polymethylmethacrylate beads (4 papers), gentamicin coated intramedullary (IM) nails (2 papers), gentamicin injections (1 paper) and antibiotic released IM core cement (1 paper). The addition of vancomycin powder did not decrease infection rates in comparison to intravenous antibiotics alone (OR 1.3, 95% CI (0.75 – 2.26)). Antibiotic coated IM Nails appear to have an association with lower infection rates than standard IM Nails. PMMA antibiotics have shown varied results in reducing infection rates depending on the individual studies. Conclusions. There are numerous methods available to deliver antibiotics locally to an open fracture site. Further high-quality research is required to provide a definitive conclusion on their efficacy irrespective of delivery method

Olecranon fractures are common injuries representing roughly 5% of pediatric elbow fractures. The traditional surgical management is open reduction and internal fixation with a tension band technique where the pins are buried under the skin and tamped into the triceps. We have used a modification of this technique, where the pins have been left out of the skin to be removed in clinic. The purpose of the current study is to compare the outcomes of surgically treated olecranon fractures using a tension-band technique with buried k-wires (PINS IN) versus percutaneous k-wires (PINS OUT). We performed a retrospective chart review on all pediatric patients (18 years of age or less) with olecranon fractures that were surgically treated at a pediatric academic center between 2015 to present. Fractures were identified using ICD-10 codes and manually identified for those with an isolated olecranon fracture. Patients were excluded if they had polytrauma, metabolic bone disease, were treated non-op or if a non-tension band technique was used (ex: plate/screws). Patients were then divided into 2 groups, olecranon fractures using a tension-band technique with buried k-wires (PINS IN) and with percutaneous k-wires (PINS OUT). In the PINS OUT group, the k-wires were removed in clinic at the surgeon's discretion once adequate fracture healing was identified. The 2 groups were then compared for demographics, time to mobilization, fracture healing, complications and return to OR. A total of 35 patients met inclusion criteria. There were 28 patients in the PINS IN group with an average age of 12.8 years, of which 82% male and 43% fractured their right olecranon. There were 7 patients in the PINS OUT group with an average age of 12.6 years, of which 57% were male and 43% fractured their right olecranon. All patients in both groups were treated with open reduction internal fixation with a tension band-technique. In the PINS IN group, 64% were treated with 2.0 k-wires and various materials for the tension band (82% suture, 18% cerclage wire). In the PINS OUT group, 71% were treated with 2.0 k-wires and all were treated with sutures for the tension band. The PINS IN group were faster to mobilize (3.4 weeks (range 2-5 weeks) vs 5 weeks (range 4-7 weeks) p=0.01) but had a significantly higher complications rate compared to the PINS OUT group (6 vs 0, p =0.0001) and a significantly higher return to OR (71% vs 0%, p=0.0001), mainly for hardware irritation or limited range of motion. All fractures healed in both groups within 7 weeks. Pediatric olecranon fractures treated with a suture tension-band technique and k-wires left percutaneously is a safe and alternative technique compared to the traditional buried k-wires technique. The PINS OUT technique, although needing longer immobilization, could lead to less complications and decreased return to the OR due to irritation and limited ROM

Fractures of the humeral diaphysis occur in a bimodal distribution and represent 3-5% of all fractures. Presently, the standard treatment of isolated humeral diaphyseal fractures is nonoperative care using splints, braces, and slings. Recent data has questioned the effectiveness of this strategy in ensuring fracture healing and optimal patient function. The primary objective of this randomized controlled trial (RCT) was to assess whether operative treatment of humeral shaft fractures with a plate and screw construct provides a better functional outcome than nonoperative treatment. Secondary objectives compared union rates and both clinical and patient-reported outcomes. Eligible patients with an isolated, closed humeral diaphyseal fracture were randomized to either nonoperative care (initial sugar-tong splint, followed by functional coaptation brace) or open reduction and internal fixation (ORIF; plate and screw construct). The primary outcome measure was the Disability Shoulder, Arm, Hand (DASH) score assessed at 2-, 6-, 16-, 24-, and 52-weeks. Secondary outcomes included the Short Musculoskeletal Functional Assessment (SMFA), the Constant Shoulder Score, range of motion (ROM), and radiographic parameters. Independent samples t-tests and Chi-squared analyses were used to compare treatment groups. The DASH, SMFA, and Constant Score were modelled over time using a multiple variable mixed effects model. A total of 180 patients were randomized, with 168 included in the final analysis. There were 84 patients treated nonoperatively and 84 treated with ORIF. There was no significant difference between the two treatment groups for age (mean = 45.4 years, SD 16.5 for nonoperative group and 41.7, SD 17.2 years for ORIF group; p=0.16), sex (38.1% female in nonoperative group and 39.3% female in ORIF group; p=0.87), body mass index (mean = 27.8, SD 8.7 for nonoperative group and 27.2, SD 6.2 for ORIF group; p=0.64), or smoking status (p=0.74). There was a significant improvement in the DASH scores at 6 weeks in the ORIF group compared to the nonoperative group (mean=33.8, SD 21.2 in the ORIF group vs. mean=56.5, SD=21.1 in the nonoperative group; p < 0 .0001). At 4 months, the DASH scores were also significantly better in the ORIF group (mean=21.6, SD=19.7 in the ORIF group vs. mean=31.6, SD=24.6 in the nonoperative group; p=0.009. However, there was no difference in DASH scores at 12-month follow-up between the groups (mean=8.8,SD=10.9 vs. mean=11.0, SD=16.9 in the nonoperative group; p=0.39). Males had improved DASH scores at all timepoints compared with females. There was significantly quicker time to union (p=0.016) and improved position (p < 0 .001) in the ORIF group. There were 13 (15.5%) nonunions in the nonoperative group and four (4.7%) combined superficial and deep infections in the ORIF group. There were seven radial nerve palsies in the nonoperative group and five (a single iatrogenic) radial nerve palsies in the ORIF group. This large RCT comparing operative and nonoperative treatment of humeral diaphyseal fractures found significantly improved functional outcome scores in patients treated surgically at 6 weeks and 4 months. However, the early functional improvement did not persist at the 12-month follow-up. There was a 15.5% nonunion rate, which required surgical intervention, in the nonoperative group and a similar radial nerve palsy rate between groups

Aim. To investigate the incidence and time-trend in reoperation due to deep Surgical Site Infection (SSI) following hip fracture surgery. Method. This was a population-based, nationwide, cohort study. We included 74,771 from the Danish Multidisciplinary Hip Fractures Register (1) consisting of patients 65 years of age or older, who underwent surgery between January 1. st. 2005 and December 31. st. 2016 for all types of hip fracture. Cross-linkage with the Danish National Patient Register and The Danish Civil Registration system was made. Demographic data extracted included vital status, civil status, gender, age, Body Mass Index (BMI), fracture classification (AO/OTA 31A-C) and surgical procedures binary registered as joint replacement or internal fixation, Charlson comorbidity index (CCI) and secondary diseases not included in CCI. Outcome was reoperations due to deep SSI in accordance with the definition from Centre for Disease Control (2). We computed cumulative incidence rates and risk ratios (RR) by calendar year periods and by different risk factors, considering death as competing risk and adjusting for age, gender, CCI, fracture type and surgery type. Results. Within 365 days of primary surgery 2.1% of all hip fractures had undergone reoperation due to deep SSI. During the period 2005–2016, the incidence of reoperation due to SSI decreased from 2.7% to 1.7%, We could not identify differences in reoperation due to SSI within one year regarding gender, BMI or CCI. Patients aged above 85 had about 50% lower risk of being reoperated compared with the youngest age group; 65–74 years (RR: 0.5; 95% CI: 0.4:0.6). The RR for reoperation due to deep SSI was lower for patients with pertrochanteric or subtrochanteric fractures (AO/OTA: 31A1-3) versus femoral neck fractures (AO/OTA: 31B1-3), RR was 0.7 (95%CI: 0.7:0.8). However, RR for surgery type (joint replacement vs internal fixation) at 365 days was significantly lower for joint replacement, RR: 0.6 (95% CI: 0.6:0.7). Conclusions. This study shows reoperation risk due to SSI for all types of hip fractures of 2.1%. There was a 45% decrease in reoperation over time from 2005 to 2016. However, the risk of revision is still high, and further action in avoidance of SSI should be taken

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

Australian Football (AF) is a popular sport in Australia, with females now representing one-third of participants. Despite this, the injury profiles of females versus males in largely unknown. The current study investigated fractures, dislocations and tendon ruptures in females versus males presenting to emergency departments (ED) with an AF injury. All patients, regardless of age, presenting to one of 10 EDs in Victoria, Australia, with an AF injury were included. Data were prospectively collected over a 10-month period, coinciding with a complete AF season. Data were extracted from patient medical records regarding injury-type, body-part injured and treatments required. Female and male data were compared with chi-squared tests. Of the 1635 patients presenting with an AF injury, 595 (36.0%) had a fracture, dislocation or tendon rupture, of whom 85 (14.3%) were female and the average age was 20.5 years (SD 8.0). Fractures accounted for most injuries (n=478, 80.3% of patients had a fracture), followed by dislocations (n=118, 19.8%) and tendon ruptures (n=14, 2.4%). Upper limb fractures were more common than lower limb fractures (71.1% v 11.5% of fractures). Females were more likely to fracture their hands or fingers than males (45.7% v 34.3%). Males were more likely to fracture ribs (5.4% v 0%). Most fractures (91.2%) were managed in the ED, with the remainder being admitted for surgery (GAMP/ORIF). Males were more likely to be admitted for surgery than females (11.2% v 5.9%). Regarding dislocations (n=118), females were more likely to dislocate the patella (36.8% v 8.1% of dislocations). Only males sustained a tendon rupture (n=14): finger extensor or flexor (57.1%), achilles tendon (28.6%) and patella tendon (14.3%). Orthopaedic AF injuries are common presentations to EDs in Victoria, though few require specialist orthopaedic intervention. Injury profiles differed between genders suggesting that gender specific injury prevention and management might be required

Malalignment is a common complication following tibial surgery, occurring in 10% of fractures. This is associated with prolonged healing time and non-union. It occurs due to inability to maintain a satisfactory reduction. A reduction device, such as the Staffordshire Orthopaedic Reduction Machine (STORM), permits the surgeon to manipulate the fracture and hold it reduced. A retrospective parallel case series was undertaken of all patients undergoing tibial nails over a six-year period from 2014 to 2021. Patient demographics were obtained from medical records. Operative times obtained from the theatre IT system and included the time patient entered theatre and surgical start and finish times for each case. Anteroposterior and lateral long leg post-operative radiographs were reviewed. Angulation was measured in both coronal and sagittal planes, by two separate orthopaedic surgeons. A reduction was classified to be ‘mal-aligned’ if the angle measured was greater than 5 degrees. One tailed unpaired t-test was used to compare alignment in each plane. Bony union was assessed on subsequent radiographs and was determined according to the Radiographic Union Score for Tibial Fractures. 31 patients underwent tibial nail during the time period. 8 patients were lost to follow up and were excluded. Of the remaining 23 patients, the STORM device was utilised in 11. The overall mean alignment was acceptable across all groups at 2.17° in the coronal plane and 2.56° in the saggital plane. Analysing each group individually demonstrated an improved alignment when STORM was utilised: 1.7° (1°–3°) vs 2.54° (0°–5°) for the coronal plane and 1.6° (0°–3°) vs 3.31° (0°–9°) in the saggital plane. This difference was significant in saggital alignment (p=0.03) and showed a positive trend in coronal alignment, although was not significant (p=0.08). The time in theatre was shorter in the control group with a mean of 113 minutes (65 to 219) in comparison to STORM with a mean of 140 minutes (105 to 180), an increased theatre time of 27 minutes (p=0.04). This study demonstrates that STORM can be used in the surgical treatment of tibial fractures resulting in improved fracture alignment with a modest increase in theatre time

Fractures of the ankle are common, and they mostly affect young adults. Wound complications are not uncommon following the fixation of these fractures. This study evaluated the impact of HIV on wound healing after plate osteosynthesis in patients with closed ankle fractures. This is an observational retrospective study of patients operated on at a tertiary level hospital. We reviewed hospital records for patients above 18 years of age who presented with wound breakdown following ankle open reduction and internal fixation. The patients’ hospital records were retrieved to identify all the patients treated for closed ankle fractures and those who developed wound breakdown. Patients with Pilon fractures were excluded. The National Health Laboratory System (NHLS) database was accessed to retrieve the CD4 count, viral load, haematology study results, and biochemistry results of these patients at the time of surgery and subsequent follow-up. The x-rays were retrieved from the electronic picture archiving system (PACS) and were assessed for fracture union at a minimum of 3 months follow-up. We reviewed the medical records of 172 patients with closed ankle fractures treated from 2018 to 2022. Thirty-one (18.0%) developed wound breakdown after surgery, and they were all tested for HIV. Most of the patients were male (58.0%), and the average age of the cohort was 43.7 years (range: 21 years to 84 years). Ten of these patients (32.2%) were confirmed HIV positive, with CD4 counts ranging from 155 to 781. Viral load levels were lower than detectable in 40% of these patients. All patients progressed to fracture union at a minimum of 3 months follow-up. We observed no difference between HIV-positive and HIV-negative patients in terms of wound breakdown and bone healing post-plate osteosynthesis for closed ankle fractures

The “Toddler Fracture” is an un-displaced oblique distal tibia fracture seen in children 9–36months of age presenting with refusal to walk, often after an unwitnessed or minor injury. Diagnosis is often made clinically, because initial x-rays are negative in up to 50% of patients, and then confirmed by the presence of periosteal reaction on follow up x-ray 7–10 days later. Point of Care Ultrasound (POCUS) has shown excellent ability to detect distal radius, clavicle and other extremity fractures and published case reports suggest that POCUS can also detect Toddler Fractures. The objective of this proof of concept study was to establish the feasibility and preliminary sensitivity and specificity of POCUS in the diagnosis of Toddler Fractures, and to characterize the POCUS findings in patients presenting with clinical Toddler Fractures. This was a prospective reviewer-blinded cross-sectional study of patients presenting to the emergency department of a paediatric tertiary care centre with presumed toddler fractures. All patients with suspected toddler fracture underwent lower limb x-ray. Those enrolled in the study also underwent POCUS of both lower extremities by a specialized provider. Treating clinicians were blinded to ultrasound results, and study sonographers were blinded to x-ray results. Study patients were then seen in paediatric orthopaedic follow up clinics 7–10 days later, and clinical assessment and follow up x-ray were performed as necessary to confirm diagnosis. Toddler Fracture was confirmed in 5 of 27 patients enrolled in the study. Preliminary results demonstrate that these POCUS findings were detected on the scan in all 5 confirmed toddler fractures. Three of these patients had an initial positive x-ray and 2 went on to have toddler fracture confirmed on follow up x-ray and orthopaedic assessment. POCUS findings consistent with a toddler fracture were found to be cortical disruption and periosteal hematoma. POCUS may be a useful adjunct to confirming a diagnosis of a toddler fracture when clinical suspicion is high and initial x-ray is negative. This pilot study provides positive impetus for further prospective study. The use of POCUS to confirm toddler fracture can decrease further radiation exposure to patients, allow early guidance to families on the management and expected recovery, and has potential to decrease burden on families and the healthcare system by potentially eliminating unnecessary follow-up appointments. Future study will help to better guide diagnostic and technical criteria, and provide guidance for appropriate medical education in this technique and interpretation

Introduction. Treatment of non-union in open tibial fractures Gustilo-Anderson(GA)-3A/3B fractures remains a challenging problem. Most of these can be dealt using treatment methods that requires excision of the non-union followed by bone grafting, masquelet technique, or acute shortening. Circular fixators with closed distraction or bone transport also remains a useful option. However, sometimes due to patient specific factors these cannot be used. Recently antibiotic loaded bone substitutes have been increasingly used for repairing infected non-unions. They provide local antibiotic delivery, fill dead space, and act as a bone conductive implant, which is resorted at the end of a few months. We aimed to assess the outcome of percutaneous injection of bone substitute while treating non-union of complex open tibial fractures. Materials & Methods. Three cases of clinical and radiological stiff tibial non-union requiring further intervention were identified from our major trauma open fracture database. Two GA-3B cases, treated with a circular frame developed fracture-related-infection(FRI) manifesting as local cellulitis, loosened infected wires/pins with raised blood-markers, and one case of GA-3A treated with an intramedullary nail. At the time of removal of metalwork/frame, informed consent was obtained and Cerament-G. TM. (bone-substitute with gentamicin) was percutaneously injected through a small cortical window using a bone biopsy(Jamshedi needle). All patients were allowed to weight bear as tolerated in a well-fitting air-cast boot and using crutches. They were followed up at 6 weekly intervals with clinical assessment of their symptoms and radiographs. Fracture union was assessed using serial radiographs with healing defined as filling of fracture gap, bridging callus and clinical assessment including return to full painless weight bearing. Results. Follow-up at 6 months showed all fractures had healed with no defect or gaps with evidence of new trabecular bone and significant resorption of Cerament-G. TM. at final follow-up. There was no evidence of residual infection with restoration of normal limb function. Fractures with no internal fixation showed a mild deformity that had developed during the course of the healing, presumed due to mild collapse in the absence of fixation. These were less than 10 degrees in sagittal and coronal planes and were clinically felt to be insignificant by the patients. Conclusions. Cerament-G's unique combination of high dose antibiotics and hydroxy apatite matrix provided by calcium sulphate might help provide an osteoconductive environment to allow these stiff non-unions to heal. The matrix appears to provide a scaffold-like structure that allows new bone in-growth with local release of antibiotics helping reduce deep-seated infections. The final deformation at fracture site underlines the need for fixation- and it is very unlikely that this technique will work in mobile nonunions. Whilst similar fractures may heal without the use of bone substitute injections, the speed of healing in presence of significant fracture gap suggests the use of these bone substitutes did help in our cases. Further studies with a larger cohort, including RCTs, to evaluate the effectiveness of this technique compared to other methods are needed

Introduction. A subset of patients in cast awaiting fixation of ankle fractures require conversion to delayed external fixation (dEF). We aimed to evaluate the effect of delayed versus planned external fixation (pEF), then identify objective characteristics contributing to need for conversion. Method. We extracted data from our booking system to identify all ankle external fixation procedures between 2010 to 2022. Exclusions included open fractures, the skeletally immature, and pilon or talus fractures. Fractures were classified using the AO/OTA classification, then a matched cohort was identified based on fracture classification. We compared the planned, delayed and matched cohorts for demographics, posterior malleolar fragment (PMF) ratio, and degree of displacement at presentation. Results. We identified 25 pEF, 42 dEF, and 67 matched patients. Ankles with dEF had a 3.8 day longer time to ORIF from presentation than those who had pEF, and had an infection rate of 9.5%, compared to 4% in the pEF group. Two patients in the dEF group required further operative intervention. There were no infections or reoperations required in the pEF or matched groups. The dEF group were more likely to have ≥2 reductions (OR 4.13), a PMF ratio of >0.23 (OR 5.07), and have increased displacement at time of injury on lateral (32% vs 19%) and AP (62% vs 36%) radiographs. Discussion. Our retrospective study highlights the longer time to operation and increased infection rates of patients who do not get timely external fixation. We propose a series of objective parameters that predict failure of cast treatment and guide the surgeon to consider planned external fixation in some ankle

The most common classification of periprosthetic femoral fractures is the Vancouver classification. The classification has been validated by multiple centers. Fractures are distinguished by location, stability of the femoral component, and bone quality. Although postoperative and intraoperative fractures are classified using the same three regions, the treatment algorithm is slightly different. Type A fractures involve the greater and lesser trochanter. Fractures around the stem or just distal to the stem are Type B and subcategorised depending on stem stability and bone quality. Type C fractures are well distal to the stem and are treated independent of the stem with standard fixation techniques. The majority of fractures are either B1 (stable stem) or B2 (unstable stem). The stem is retained and ORIF of the fracture performed for B1 fractures. B2 and B3 fractures require stem revision with primary stem fixation distal to the fracture. Intraoperative fractures use the same A, B, C regions but are subtyped 1–3 as cortical perforations, nondisplaced, and displaced unstable fractures, respectively. With the exception of A1 intraoperative fractures all other intraoperative fractures require surgical treatment. A recent publication utilizing a New York state registry highlighted the patient risk of mortality associated with periprosthetic hip fractures. One month, 6 month and 1 year mortality was 3.2%, 3.8% and 9.7%, respectively. The mortality risk was lower for periprosthetic fractures treated with ORIF at 1 and 6 months compared to fractures requiring revision total hip

In 2007, the National Hip Fracture Database (NHFD) was conceived in the United Kingdom (UK) as a national audit aiming to improve hip fracture care across the country. It now represents the world's largest hip fracture registry. The purpose of the NHFD is to evaluate aspects of best practice for hip fracture care, at an institutional level, that reflect the evidence-based clinical guidelines and quality standards developed by the National Institute for Health and Care Excellence. No national program currently exists, equivalent to the NHFD, in Canada despite evidence suggesting that national audit programs can significantly improve patient outcomes. The purpose of this study was to evaluate aspects of best practice for hip fractures at our Canadian academic tertiary referral center using the Key Performance Indicators (KPI) and benchmarks used by the NHFD. In doing so, we aimed to compare our performance to other hospitals contributing to the NHFD database. A retrospective cohort study was conducted on consecutive patients who presented to our Canadian center for surgical management of a hip fracture between August 2019 to September 2020. Fracture types included intertrochanteric, subtrochanteric, and femoral neck fractures treated with either surgical fixation or arthroplasty. Cases were identified from the affiliate institute's Operatively Repaired Fractures Database (ORFD). The ORFD prospectively collects patient-level data extracted from electronic medical records, operating room information systems, and from patients’ discharge summaries. All applicable data from our database were compared to the established KPI and benchmarks published by the NHFD that apply to the Canadian healthcare system. Six hundred and seven patients’ data (64.5% female) were extracted from the ORFD, mean age 80.4 ± 13.3 years. The NHFD contains data from 63,284 patients across the entire UK. The affiliate institute performed inferiorly compared to the NHFD for two KPIs: prompt surgery (surgery by the day following presentation with hip fracture, 52.8% vs. 69%) and prompt mobilization after surgery (mobilized out of bed by the day after operation, 43.0% vs. 81.0%). However, more patients at the affiliate institute were not delirious when tested postoperatively (89.6% vs. 68.4%). There was no significant difference in the average length of stay (12.23 days versus 13.5 days) or in 30-day mortality rate (8.4% versus 8.3%). More than half of all KPI's and benchmarks for patients receiving a hip fracture surgery at our tertiary referral center in Canada ranked significantly lower than patients receiving a hip fracture surgery in the UK. These findings indicate that perhaps a national audit program should be implemented in Canada to improve aspects of hip fracture care, at an institutional level. Following evidence-based clinical guidelines and using standardized benchmarks would encourage change and foster improvement across Canadian centres when necessary

Introduction

Diaphyseal tibial fractures account for approximately 1.9% of adult fractures. Studies have demonstrated a high proportion have ipsilateral occult posterior malleolus fractures. We hypothesize that this rotational element will be highlighted using the Mason & Molloy Classification.

Introduction

Open fractures of the tibia are disabling injuries with a significant risk of deep infection. Treatment involves early antibiotic administration, early and aggressive surgical debridement, and may require complex soft tissue coverage techniques. The extent of disruption to the skin and soft-tissue envelope often varies, with ‘simple’ open fractures (defined by the Orthopaedic Trauma Society (OTS) open fracture severity classification) able to be closed primarily, whilst others may require shortening or soft-tissue reconstruction. This study aimed to determine whether OTS simple tibial open fractures received different rates of adequate debridement and plastic surgical presence at initial debridement, compared with OTS complex injuries, and whether rates of fracture-related infection, nonunion, or reoperation differed between the groups.

High energy pelvic injury poses a challenging setting for the treating surgeon. Often multiple injuries are associated, which makes the measurement of short- and long-term functional outcomes a difficult task. The purpose of this study was to determine the incidence of pelvic dysfunction and late impacts of high energy pelvic ring fractures on pelvic floor function in women, with respect to urinary, sexual and musculoskeletal function. This was compared to a similar cohort of women with lower limb fractures without pelvis involvement.

The data in our study was prospectively gathered between 2010 and 2013 on 229 adult females who sustained injury between 1998 and 2012. Besides demographic and operative variables, the scores of three validated health assessment tools were tabulated: King's Health Questionnaire (KHQ), Female Sexual Function Index (FSFI) and the Short Musculoskeletal Functional Assessment (SMFA). A multivariate regression analysis was done to compare groups.

The incidence of sexual dysfunction was 80.8% in the pelvis and 59.4% in the lower extremity group. A Wilcoxon rank sum test showed a significant difference in KHQ-score (p<0.01) with the pelvis group being worse. When adjusting for age, follow-up and Injury Severity Score this difference was not significant (p=0.28), as was for FSFI and SMFA score. The mean FSFI scores of both groups met the criteria for female sexual dysfunction (<26). Patients with a Tile C fracture have better FSFI scores (16.98) compared to Tile B fractures (10.12; p=0.02). Logistic regression predicting FSFI larger than 26.5 showed that older age and pelvic fractures have a higher likelihood having a form of sexual dysfunction.

Sexual dysfunction after lower extremity trauma is found in patients regardless of pelvic ring involvement. Urinary function is more impaired after pelvic injuries, but more data is needed to confirm this. Older age and pelvic fracture are predictors for sexual dysfunction in women. This study is important as it could help counsel patients on the likelihood of sexual dysfunction, something that is probably under-reported and recognized during our patient follow up.

Introduction. Intramedullary nailing is gaining popularity for treatment of distal tibial fractures due to short operative time and minimum surgical trauma to soft tissues. Distal tibial fractures are commonly associated with concurrent fibular fractures at, above or below the level of tibial fractures. So far there is no consensus for fixation of fibular fractures. Materials and Methods. Fractures of fibula at or below the level of fracture of tibia were taken into consideration. Fractures of fibula above the tibial level were excluded because they do not add to stability of fracture fixation. Retrospective study was done and distal tibia-fibula fractures were separated into 2 groups based on whether fibula was fixed or not. Measures of angulation were obtained from radiographs taken immediately after the surgery, a second time 3 months later, and at 6-month follow-up. Results. 35 fracture of distal tibia and fibula were included in study. Fibula was not fixed in 21 cases while 14 fibular fixations were carried out either using short plates(8) or intramedullary pins(6). No significant differences were observed for malalignment in fracture of fibula at the level of tibial fractures. However for fractures of fibula at a level lower than its tibial counterpart, fixation of fibula significantly reduced malalignment. Conclusion. Fixation of fibula has a definite role in reducing malunion in cases where fibula was fractured below the level of tibial fracture. Fixation of fibula may increase overall stability of fixation of tibia and reduce malunion

As the incidence of total hip arthroplasty (THA) rises, an increasing prevalence of peri-prosthetic femur fractures has been reported. This is likely due to the growing population with arthroplasties, increasing patient survival and a more active life-style following arthroplasty. It is the 3rd most common reason for THA reoperation (9.5%) and 5th most common reason for revision (5% with fracture risk after primary THA reported at 0.4%-1.1% and after revision at 2.1%-4%). High quality radiographs are usually sufficient to classify the fracture and plan treatment. Important issues in treatment include stem fixation status and fracture location relative to the stem. Additional comorbidities will also influence treatment choices, of which the most critical is the presence of infection and the quality of bone stock. The most commonly studied, and reported classification system is the Vancouver. Type A are peri-trochanteric fractures with AL at the lesser and AG at the greater trochanter. B fractures are those around the stem with B1 fractures having a well-fixed stem, B2 a loose stem with adequate bone stock, and B3 representing loose stem and inadequate bone stock. C fractures are distal to the stem. Type A) Trochanteric Fractures: These are usually associated with lysis. Displaced fractures can be managed adequately with cerclage fixation and cancellous allograft to fill osteolytic defects. Undisplaced fractures usually heal well with symptomatic treatment. Type B) Fractures Around the Stem: The B1 type has a well-fixed component and is usually treated with extramedullary fixation plus graft. Contemporary plates have been designed specifically for these fractures. Strut allograft may be used to provide a more rigid construct. Spiral and long oblique fractures can be cerclaged while short oblique or transverse fractures require fixation anterior and lateral with cable plates and cortical strut grafts. Screws can be used distal to the implant, and cables used proximally. The B2 type has a loose prosthesis but otherwise good bone stock. In this setting, the fracture line may be extended on the lateral cortex of the femur as an extended osteotomy to provide easy access for cement removal. These fractures can be managed with an extensively coated stem if rotational stability can be obtained in the distal segment. If rotational stability over a 4 cm scratch interference fit of the stem isn't possible, then a fluted tapered modular stem should be used. Strut allografts improve initial stability. The B3 type has both a loose prosthesis and poor bone stock and in the younger patient restoration of bone stock should be a priority. Bulk femoral grafts may be needed. The elderly or low functional demand patient may be treated with a proximal femoral replacement. Because of soft-tissue deficiencies, a constrained acetabular liner may be needed to prevent instability. Type C) Fractures Distal to the Stem: These usually accompany a stable stem and many fixation devices are available. Locking plates have become most popular and should be secured with cerclage wires proximally around the component with screws distally. Retrograde nails may be employed if there is adequate bone distal to the stem tip and above the fracture
