Aims. 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. Methods. 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. Results. 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). Conclusion. 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 treated nonoperatively, locked anterior-plate fixation remains the predominant method of fixation for fractures of the distal radius; this is despite questions and continued debate about the best method of surgical fixation for these injuries.

Excessive resident duty hours (RDH) are a recognized issue with implications for physician well-being and patient safety. A major component of the RDH concern is on-call duty. While considerable work has been done to reduce resident call workload, there is a paucity of research in optimizing resident call scheduling. Call coverage is scheduled manually rather than demand-based, which generally leads to over-scheduling to prevent a service gap. Machine learning (ML) has been widely applied in other industries to prevent such issues of a supply-demand mismatch. However, the healthcare field has been slow to adopt these innovations. As such, the aim of this study was to use ML models to 1) predict demand on orthopaedic surgery residents at a level I trauma centre and 2) identify variables key to demand prediction. Daily surgical handover emails over an eight year (2012-2019) period at a level I trauma centre were collected. The following data was used to calculate demand: spine call coverage, date, and number of operating rooms (ORs), traumas, admissions and consults completed. Various ML models (linear, tree-based and neural networks) were trained to predict the workload, with their results compared to the current scheduling approach. Quality of models was determined by using the area under the receiver operator curve (AUC) and accuracy of the predictions. The top ten most important variables were extracted from the most successful model. During training, the model with the highest AUC and accuracy was the multivariate adaptive regression splines (MARS) model, with an AUC of 0.78±0.03 and accuracy of 71.7%±3.1%. During testing, the model with the highest AUC and accuracy was the neural network model, with an AUC of 0.81 and accuracy of 73.7%. All models were better than the current approach, which had an AUC of 0.50 and accuracy of 50.1%. Key variables used by the neural network model were (descending order): spine call duty, year, weekday/weekend, month, and day of the week. This was the first study attempting to use ML to predict the service demand on orthopaedic surgery residents at a major level I trauma centre. Multiple ML models were shown to be more appropriate and accurate at predicting the demand on surgical residents as compared to the current scheduling approach. Future work should look to incorporate predictive models with optimization strategies to match scheduling with demand in order to improve resident well being and patient care

Introduction. Fracture related infection (FRI) is a challenging complication to manage in an orthoplastic setting. Consensus guidelines have been created to standardise the diagnosis of FRI and comprise confirmatory and suggestive criteria. In this study, the aim is to assess the diagnostic criteria and management of FRI with a particular focus on soft tissue reconstruction. Materials & Methods. A retrospective study to identify the outcomes of FRI in the lower limb over a five year period at a Major Trauma Centre. Fracture specific information that was analysed includes: open versus closed, fractured bone(s) and site, initial fracture management, method of diagnosis and soft tissue management. Results. A total of 40 patients were identified, 80% of whom were male (n= 32). The mean age for FRI diagnosis was 54 years (range 18–83 years). In our patient cohort, 10% were immunosuppressed and another 12.5% had a formal diagnosis of Diabetes Mellitus. A diagnosis of acute FRI (i.e. < six weeks from time of injury) was made in 9 patients (22.5%). Chronic FRI was noted in 25 patients (62.5%). There was equal incidence of FRI in patients with closed fractures and open fractures (42.5%). Tibia and fibula fractures were most common (87.5%, n=35). Regardless of fractured bone(s), the more distal the fracture the higher the incidence of FRI (60% distal versus 12.5% proximal). Gram-positive cocci were the most commonly identified pathogens, identified in 25% of patients. Five patients underwent free flap reconstruction, two patients received pedicled muscle flaps and another two patients received split thickness skin grafts. Conclusions. The diagnosis of FRI can be confirmed through the presence of a combination of confirmatory and suggestive criteria. We advocate a staged approach in the management of FRI with radical wound excision and temporary coverage followed by definitive soft tissue reconstruction

Aims. The BOA/BAPRAS guidelines for the management of open tibial fractures (2009) recommend early senior combined orthoplastics input and appropriate facilities to manage a high caseload. St Georges Hospital is one of four London Trauma Centres fulfilling these criteria. Our aim is to determine whether becoming a trauma centre has affected the management of patients with open tibial fractures. Methods. Data were obtained prospectively on consecutive open tibial fractures during two 8 month periods: before and after becoming a Major Trauma Centre (May 2009–Dec 2009 and April 2010–Oct 2010 respectively). Data on patient pathway including, admitting hospital, length of stay, timing and number of operations were recorded. Results. 29 open tibial fractures were admitted during the 8 months after designation as a major trauma centre compared to 15 before. 72% of patients came directly, or as A&E hot transfers (previously 60%). Of the eight tertiary transfers, six were from hospitals outside the South West Trauma Network. The time to transfer patients initially admitted to local orthopaedic departments has fallen from 8.6 to 1.6 days. Despite this improvement as a trauma centre, these patients remained in hospital longer (16.3 vs 14.9) and had more operations (3.7 vs 2.6) than direct admissions. As a trauma centre there were improvements in time to definitive skeletal stabilisation (4.7 to 2.2), skin coverage (8.3 to 3.7 days), average number of operations (4.2 to 2.3) and average length of hospital admission fell from 23 to 16 days. Conclusions. The volume and management of open tibial fractures has been directly affected by introduction of a trauma centre within the London Trauma Network. Implementation of BOAST guidelines has resulted in improved management of open lower limb fractures independent of fracture grade. Our data strongly support the continuing development of trauma networks

Open tibial fractures can be difficult to manage, with a range of factors that could affect treatment and outcome. We present a large cohort of patients, and analyse which factors have significant associations with infection outcome. Elucidation will allow clinicians to strive for treatment optimisation, and patients to be advised on likely complications. Open tibia fractures treated at a major trauma centre between 2015-2021 were included. Mean age at injury was 55.4 (range 13-102). Infection status was categorized into no infection, superficial infection, and osteomyelitis. Age, mode of injury, polytrauma, fibula status, Gustilo-Anderson (GA) classification, wound contamination, time from injury to: first procedure/definitive plastics procedure/definitive fixation, type of definitive fixation, smoking and diabetic status, and BMI, were collected. Multicollinearity was calculated, with highly correlated factors removed. Multinomial logistic regression was performed. Chi Squared testing, with Post Hoc Bonferroni correction was performed for complex categorical factors. Two hundred forty-four patients with open tibial fractures were included. Forty-five developed superficial infection (18.4%), and thirty-nine developed osteomyelitis (16.0%). Polytrauma, fibula status, and type of definitive fixation were excluded from the multivariate model due to strong multicollinearity with other variables. With reference to the non-infected outcome; superficial infection patients had higher BMI (p<0.01), higher GA grade (p<0.01), osteomyelitis patients had longer time to definitive fixation (p=0.049) and time to definitive plastics procedure (p=0.013), higher GA grade (p<0.01), and positive wound contamination(p=0.015). Poc hoc analysis showed “no infection” was positively associated with GA-I (p=0.029) and GA-II (p<0.01), and negatively associated with GA-IIIC (p<0.01). Osteomyelitis was positively associated with GA-IIIc (p<0.01). This study investigated the associations between the injury and presentation factors that may affect infection outcome. The variables highlighted are the factors clinicians should give extra consideration to when treating cases, and take preventative measures to optimize treatment and mitigate infection risk

The second wave of COVID-19 infections in 2021 resulting from the delta strain had a significantly larger impact on the state of New South Wales, Australia and with it the government implemented harsher restrictions. This retrospective cohort study aims to explore how the increased restrictions affected hand trauma presentations and their treatment. Retrospective analysis was performed on patients who underwent hand surgery from the period of June 23 – August 31 in 2020 and 2021 at a level one trauma centre in Western Sydney. During the second-wave lockdown there was an 18.9% decrease in all hand trauma presentations. Despite widespread restrictions placed on the manufacturing, wholesale, retail and construction industries, there was an insignificant difference in work injuries. Stay-at-home orders and reduced availability of professional tradespersons likely contributed to an increase in DIY injuries. Significant reductions in metacarpal and phalangeal fractures coincided with significantly curtailed sporting seasons. The findings from this study can assist in predicting the case-mix of hand trauma presentations and resource allocation in the setting of future waves of COVID-19 and other infectious diseases

Abstract. Introduction. Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Methods. Eighty-seven patients with knee dislocation were treated at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 4 weeks was preferred unless the patient was too unstable (Injury severity score>16). The collaterals were repaired and augmented using a variety of autografts, allografts or synthetic grafts. PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score. Results. The mean age of the patients was 33.6yrs (SD 11.9), 66 males and 21 females. According to Schenck classification, 26 were KD-I (30%), 6 KD-II (7%), 13 were KD-III (15%), 7 were KD-IV (8%) and 35 were KD-V (40%). 7 patients had CPN injury (8%), 3 had vascular injury (3.4%), 2 had combined CPN and vascular injury (2.3%). Acute surgical treatment was done in 62 patients while 10 had staged reconstruction. 22 patients had delayed reconstruction. The mean follow-up period was 5.8 years (1- 12 yrs), mean IKDC score was 57.6 (SD 23.6). The mean Tegner activity scale postoperatively was 4.5(SD 2) and the mean KOOS score was 74.9 (SD 19.6). Conclusion. A large proportion of cases were KD-V but still had a good outcome with surgical management. Current classification systems do not cover all dislocation patterns and a modification is proposed

Management of complex posterior malleolar fractures requires a detailed appreciation of ligamentous and bony anatomy for optimal fracture fixation and restoration of articular congruency. Pre operative planning is vitally important to determine the surgical strategy for complex ankle fractures. We evaluated pre operative planning strategy pre and post implementation of BOAST 12 guidelines (2016) focussing on pre operative CT scans prior to definitive fixation at a major trauma centre. A multi-surgeon retrospective review of prospectively collected data from 2013 to 2018 was performed at a major trauma centre. Patients who had sustained a posterior malleolar fracture and definitive fixation were identified. Information was collated from PICS, PACS, the trauma database and operative notes. 134 patients were identified over a 5 year period who had sustained a posterior malleolar fracture and had definitive fixation. (Pre BOAST guidelines = 61, Post BOAST guidelines = 73). Prior to the implementation of BOAST guidelines ¼ with posterior malleolar fractures did not have a pre operative CT scan (15/61). Post implementation of BOAST 12 90% (66/73)patients with fixation of posterior malleolus fractures had a pre operative CT scan. Posterior malleolus surgery most commonly took place In patients between 18–30 years. Following implantation of BOAST 12 guidelines there was a 15% increase in pre operative CT scanning for ‘complex ankle fractures'. Changes in national guidelines have heavily influenced pre operative planning strategy for ankle fractures at University Hospitals Birmingham. A detailed appreciation of fracture pattern pre operatively helps guide surgical strategy

Fracture related infections (FRI) are debilitating complications of musculoskeletal trauma surgery that can result in permanent functional loss or amputation. This study aims to determine risk factors associated with FRI treatment failure, allowing clinicians to optimise them prior to treatment and identify patients at higher risk. A major trauma centre database was retrospectively reviewed over a six-year period. Of the 102 patients identified with a FRI (66 male, 36 female), 29.4% (n=30) had acute infections (onset <6 weeks post-injury), 34.3% (n=35) had an open fracture. Open fractures were classified using Gustilo-Anderson (GA) classification (type 2:n=6, type 3A:n=16, type 3B:n=10, type 3C:n=3). Patients with periprosthetic infections of the hip and knee joint, those without prior fracture fixation, soft tissue infections, diabetic foot ulcers, pressure sore infections, patients who died within one month of injury, <12 months follow-up were excluded. FRI treatment failure was defined as either infection recurrence, non-union, or amputation. Lifestyle, clinical, and intra-operative data were documented via retrospective review of medical records. Factors with a P-value of p<0.05 in univariate analysis were included in a stepwise multivariate logistic regression model. FRI treatment failure was encountered in 35.3% (n=36). The most common FRI site was the femoral shaft (16.7%; n=17), and 15.7% (n=16) presented with signs of systemic sepsis. 20.6% (n=21) had recurrent infection, 9.8% (n=10) had non-union, and 4.9% (n=5) required an amputation. The mean age at injury was 49.71 years old. Regarding cardiovascular risk factors, 37 patients were current smokers (36.3%), 31 patients were diabetics (30.4%), and 32 patients (31.4%) were obese (BMI≥30.0). Average follow-up time was 2.37 (range: 1.04-5.14) years. Risk factors for FRI treatment failure were BMI>30, GA type 3c, and implant retention. Given that FRI treatment in 35.3% (36/102) ended up in failure, clinicians need to take into account the predictive variables analysed in this study, and implement a multidisciplinary team approach to optimise these factors. This study could aid clinicians to redirect efforts to improve high risk patient management, and prompt future studies to trial adjuvant technologies for patients at higher risk of failure

Complications are an inevitable part of orthopaedic surgery, how one defines complications can have an impact on the ability to learn from them. A group of general surgeons headed by Clavien and Dindo et al.1 have previously published their classification system for surgical complications based on the type of therapy required to correct the complication. Our aim was to evaluate a modification of this classification system and its use over a 12-month period at our institution via our departmental audits, our hypothesis being that this would direct appropriate discussion around our complications and hence learning and institutional change. A modified Clavien-Dindo Classification was prospectively applied to all complications recorded in the Orthopaedic departmental quarterly audits at our institution for a 12-month period (4 audits). The audit discussion was recorded and analysed and compared with the quarterly complication audits for the preceding 12-month period. The modified Clavien-Dindo classification for surgical complications was applicable and reproducible to Orthopaedic complications in our level 1 trauma centre. It is a transparent system, objective in its interpretation and avoids the tendency to down-grade serious complications. It was easy to apply and directed discussion appropriately at our quarterly audit meetings on complications where there was a preventable outcome or important learning point. In particular modifications to VTE and Death classes allowed the unit to focus discussion on cases where complication was preventable or unexpected. The modified Clavien-Dindo classification system is an easy to use and reproducible classification system for Orthopaedic complications in our unit it directed audit discussion towards cases where complications were preventable or had a learning point

Aims. In this study, we aimed to determine whether designation as a major trauma centre (MTC) affects the quality of care for patients with a fracture of the hip. . Patients and Methods. All patients in the United Kingdom National Hip Fracture Database, between April 2010 and December 2013, were included. The indicators of quality that were recorded included the time to arrival on an orthopaedic ward, to review by a geriatrician, and to operation. The clinical outcomes were the development of a pressure sore, discharge home, length of stay, in-hospital mortality, and re-operation within 30 days. . Results. There were 289 466 patients, 49 350 (17%) of whom were treated in hospitals that are now MTCs. Using multivariable logistic and generalised linear regression models, there were no significant differences in any of the indicators of the quality of care or clinical outcomes between MTCs, hospitals awaiting MTC designation and non-MTC hospitals. Conclusion. These findings suggest that the regionalisation of major trauma in England did not improve or compromise the overall care of elderly patients with a fracture of the hip. Take home message: There is no evidence that reconfiguring major trauma services in England disrupted the treatment of older adults with a fracture of the hip. .

In response to the COVID-19 pandemic public health measures were implemented to limit virus spread. After initial implementation of a province-wide lockdown (Stage 1), there followed a sequential ease of restrictions through Stages 2 and 3 over a 6-month period from March to September 2020 (Table 1). We aimed to determine the impact of COVID-19 public health measures on the epidemiology of operative paediatric orthopaedic trauma and to determine differential effects of each stage of lockdown. A retrospective cohort study was performed comparing all emergency department (ED) visits for musculoskeletal trauma and operatively treated orthopaedic trauma cases at a Level-1 paediatric trauma center during Mar-Sep 2020 (pandemic), compared with Mar-Sep 2019 (pre-pandemic). All operative cases were analyzed based on injury severity, mechanism of injury (MOI) and anatomic location (AL). Comparisons between groups were assessed using chi-square testing for categorical variables, and student t-tests and Fisher's exact tests for continuous variables. During the pandemic period, ED visits for orthopaedic trauma decreased compared to pre-pandemic levels by 23% (1370 vs 1790 patients) and operative treatment decreased by 28% (283 vs 391 patients). There was a significant decrease in the number of operative cases per day in lockdown Stage 1 (1.25 pandemic vs 1.90 pre- pandemic; p < 0 .001) and Stage 2 (1.65 pandemic vs 3.03 pre-pandemic; p< 0.001) but no difference in operative case number during Stage 3 (2.18 pandemic vs 2.45 pre-pandemic; p=0.35). Significant differences were found in MOI and AL during Stage 1 (p < 0 .001) and Stage 2 (p < 0 .001) compared to pre-pandemic. During Stage 1 and 2, playground injuries decreased by 95% and 82%, respectively; sports injuries decreased by 79% and 13%, and trampoline injuries decreased 44% and 43%, compared to pre-pandemic. However, self-propelled transit injuries (bicycles/skateboards) increased during Stage 1 and Stage 2 by 67% and 28%, respectively compared to pre- pandemic. During lockdown Stage 3 there were no differences in MOI nor AL. There were no significant differences in injury severity in any lockdown stage compared to pre-pandemic. COVID-19 lockdown measures significantly reduced the burden of operative paediatric orthopaedic trauma. Differences in volume, mechanism and pattern of injuries varied by lockdown stage offering evidence of the burden of operative trauma related to specific childhood activities. These findings will assist health systems planning for future pandemics and suggest that improvements in safety of playgrounds and self-propelled transit are important in reducing severe childhood injury requiring operative intervention.

Aims. As the world continues to fight successive waves of COVID-19 variants, we have seen worldwide infections surpass 100 million. London, UK, has been severely affected throughout the pandemic, and the resulting impact on the NHS has been profound. The aim of this study is to evaluate the impact of COVID-19 on theatre productivity across London’s four major trauma centres (MTCs), and to assess how the changes to normal protocols and working patterns impacted trauma theatre efficiency. Methods. This was a collaborative study across London’s MTCs. A two-month period was selected from 5 March to 5 May 2020. The same two-month period in 2019 was used to provide baseline data for comparison. Demographic information was collected, as well as surgical speciality, procedure, time to surgery, type of anaesthesia, and various time points throughout the patient journey to theatre. Results. In total, 1,243 theatre visits were analyzed as part of the study. Of these, 834 patients presented in 2019 and 409 in 2020. Fewer open reduction and internal fixations were performed in 2020 (33.5% vs 38.2%), and there was an increase in the number of orthoplastic cases in 2020 (8.3% vs 2.2%), both statistically significant results (p < 0.000). There was a statistically significant increase in median time from 2019 to 2020, between sending for a patient and their arrival to the anaesthetic room (29 vs 35 minutes; p = 0.000). Median time between arrival in the anaesthetic room and commencement of anaesthetic increased (7 to 9 minutes; p = 0.104). Conclusion. Changes in working practices necessitated by COVID-19 led to modest delays to all aspects of theatre use, and consequently theatre efficiency. However, the reality is that the major concerns of impact of service did not occur to the levels that were expected. Cite this article: Bone Jt Open 2021;2(10):886–892

Abstract. Background. Alcohol has been associated with up to 40% trauma-related deaths globally. In response to the Covid-19 pandemic, the United Kingdom (UK) entered a state of ‘lockdown’ on 23. rd. March 2020. Restrictions were most significantly eased on 1. st. June 2020, when shops and schools re-opened. This study aimed to quantify the effect of lockdown on trauma admissions specifically regarding alcohol-related trauma. Methods. All adult patients admitted as ‘trauma calls’ to a London Major Trauma Centre (MTC) during April 2018 and April 2019 (pre-lockdown; N=316), and 1. st. April – 31. st. May 2020 (lockdown; N=191) had electronic patient records (EPR) analysed. Patients’ blood alcohol level (BAC) combined with records of intoxication were used to identify alcohol-related trauma. Multiple regression analyses were performed to compare pre- and post-lockdown alcohol-related trauma admissions. Results. Alcohol-related trauma was present in a significantly higher proportion of adult trauma calls during lockdown (lockdown 60/191 (31.4%), versus pre-lockdown 62/316 (19.6%); Odds Ratio (OR 0.83, 95% CI 0.38 to 1.28, p<0.001). Lockdown was also associated with increased weekend admissions of trauma (lockdown 125/191 weekend (65.5%) vs pre-lockdown 179/316 (56.7%); OR -0.40, 95% CI -0.79 to -0.02, p=0.041). No significant difference existed between the age, gender, or mechanism between pre-lockdown and lockdown cohorts (p>0.05). Conclusion. UK lockdown was independently associated with an increased proportion of alcohol-related trauma. Furthermore, trauma admissions were increased during the weekend when staffing levels are reduced. With the possibility of multiple global ‘waves’ of Covid-19, the risk of long-term repercussions of dangerous alcohol-related behaviour must be addressed

Introduction. Open fractures are managed in the UK guided by standards issued by the BOAST-4 standards. A study was undertaken to evaluate compliance with these standards in a regional trauma unit (MTU), and compared following upgrading to a Major Trauma Centre (MTC). Methods. Compliance was assessed against 11 of the 15 BOAST-4 standards (7, 9, 10 and 15 were not assessed). Patients were included with open diaphyseal tibial fractures (AO 42-), admitted to the department in the year before and the year after the Major Trauma Centre opened. Results. A total of 78 patients were evaluated; 30 within the MTU and 48 as a MTC. Of the 11 standards assessed, 6 (at least in part), achieved 100% compliance in the MTU study, and 5 in the MTC study. Compliance was poor for; antibiotic use in relation to definitive wound closure, formulating a joint plan, and undergoing surgery on a planned trauma list. In contrast, following MTC status antibiotic compliance had improved, as had evidence of joint planning, although antibiotic administration time on admission had declined. Consultant-level orthopaedic and plastic surgeon involvement at first intervention had improved, although plastic surgical input remained predominantly registrar-led. Time from injury to definitive stabilisation improved following MTS status. Discussion. This study demonstrates improvements in many aspects of care for open fracture since the MTC opened. However, further improvements can be made, particularly regarding the early treatment pathway. Since this audit a plastic surgeon with specific interest in lower limb reconstruction has been appointed

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

The arrival of major trauma centres (MTC) to Scotland highlights the need for structured management of polytrauma patients. The aim was to report the epidemiological profile of polytrauma patients (Injury Severity Score (ISS) 15) admitted to a large trauma unit in the UK and gather information about the initial management of this severely injured cohort. Prospectively collected data from the Scottish Trauma Audit Group (STAG) database of 366 polytrauma patients (ISS <15 & aged ≥13 years) admitted to a single trauma unit, from 1st January 2013 to 31st October 2017 was analysed. Data included patient demographics, injury characteristics, length of stay (LOS) and survivorship. The median age was 49 years (range 13–93) and females made up 31.1% of the population. There was a mean ISS of 25.7 (range 15–75) and mean LOS of 19 days. The overall mortality rate was 21%. Higher mortality occurred among females (p<0.001), patients ≥60 years age (p<0.001), patients who sustained their injury at home (p<0.0001), and those with head injuries (p<0.01). Orthopaedic injuries were present in 187 patients (51.1%) with a mortality rate of 10.7%. The most common mechanism of injury was road traffic collision (41.5%) and these patients had a significantly higher ISS (p<0.01). A fall from height <2m was associated with higher mortality (p=0.01). This study is the largest of its kind and presents a detailed epidemiological profile of patients attending a large UK trauma unit. This knowledge will help guide initial management and aid in resource and capacity planning for the future

The Victorian state government introduced a trial electronic scooter sharing scheme on 1. st. February 2022 in inner city Melbourne. Despite epidemiological data from other jurisdictions that show these devices are associated with significant trauma. This is a descriptive study from the largest trauma centre in Victoria demonstrating the “scope of the problem” after introduction of this government-approved, ride sharing scheme. Retrospective case series. Our hospital orthopaedic department database was searched from 1/1/2021 to 30/6/22 to identify all presentations associated with electronic scooter trauma, the mechanism of injury and admission information was confirmed via chart review. Data collected included: mode of arrival, alcohol/drug involvement, hospital LOS, injury severity score, ICU admission, list of injuries, operations undertaken, surgical procedures, discharge destination, death. In the 12 months prior to and 5 months since introduction of the ride share scheme, 43 patients were identified. 18 patients (42% of our cohort) presented in the 5 months since ride sharing was introduced, and 25 patients in the preceding 12 months. 58% were found to be alcohol or drug affected. All patients were admitted to hospital, 14% of which included ICU admission. 44% were polytrauma admissions. Median hospital length of stay was 2 days. The longest individual hospital stay was 69 days. No patients in this series died. There were 49 surgical procedures in 35 patients including neurosurgical, plastics and maxillofacial operations. Mean Injury Severity Score was 10. Despite data demonstrating their danger in other jurisdictions, the Victorian state government approved a trial of an electronic scooter ride share scheme in inner Melbourne in February 2022. These devices are associated with a significant trauma burden and the rate has increased since the introduction of the ride-sharing scheme. This data may be combined with other hospital data and could be used to inform policy makers

Introduction. Blunt trauma of the lower limb can lead to vascular injury causing devastating outcomes, including loss of limb and even loss of life. The primary aim of this study was to determine the limb salvage rate of patients sustaining such injuries when treated at Leeds General Infirmary (LGI) since becoming a Major Trauma Centre (MTC). Secondary aims included establishing the patient complications and outcomes. Materials and Methods. Retrospective analysis found that from 2013–18, 30 patients, comprising of 32 injured limbs, were treated for blunt trauma to the lower limb associated with vascular injury. Long-term functional outcomes were determined using postal and telephone questionnaires. Results. Twenty-four patients were male and 6 were female, their mean ages were 32 and 49 respectively. Of the 32 limbs, 27 (84%) were salvaged. Three limbs were deemed unsalvageable and underwent primary amputation; of the remaining 29 potentially salvageable limbs, 27 (93%) were saved. Eleven limbs had prophylactic fasciotomies, 3 limbs developed compartment syndrome – all successfully treated, and three contracted deep infections – one of which necessitated amputation. All but 1 patient survived their injuries and were discharged from hospital. Of the 15 questionnaire responses, self-reported limb function was understandably worse post-injury with patients experiencing mild pain on average. In addition, there was a long-standing psychological impact and the injuries altered many patients’ normal lives significantly, 10 experiencing financial difficulties and 6 having changed or lost jobs post-injury. Conclusions. Fortunately, 27 (84%) limbs were salvaged and nearly all patients survived these injuries when treated at an MTC. Whilst the number of complications was low, the future challenges these patients face are wide-ranging and significant
