Abstract. Background. University Hospital of Wales (UHW) went live as a Major Trauma Centre (MTC) on the 14th September 2020. New guidelines have been set up by the Wales Trauma Network. Aim. Prospective audit to see how many admissions, correct pathways were followed?. Materials & Methods. Prospective data collection prospective over a period of 3 months: starting from 8.11.2020 to 31.01.2021. Results. Spinal admissions represent around 22% of MTC admissions. The closing loop showed higher amount of admission (45 in comparison with the first audit 28). 42 patients had fractures where three had cord syndromes. 13 patients out of the 45 (29%) were managed operatively. After changing to MTC, more indirect referral from other hospitals representing 64% of total admission with one wrong referral (2.2%) that came to the MTC and could have been managed locally. On the other hand, repatriation rate has improved from 61% to 84%, however, repatriation time was longer than expected with >1 week represents 78%. Conclusions. Changing to MTC had a great impact with increased work load in the trust. Repatriation would be aimed for within 72 hours from treatment either conservative or postoperative. More attention should be paid towards the appropriate referral pathways to avoid wrong referral

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.

Aims. To compare the early management and mortality of older patients sustaining major orthopaedic trauma with that of a younger population with similar injuries. Patients and Methods. The Trauma Audit Research Network database was reviewed to identify eligible patients admitted between April 2012 and June 2015. Distribution and severity of injury, interventions, comorbidity, critical care episodes and mortality were recorded. The population was divided into young (64 years or younger) and older (65 years and older) patients. Results. Of 142 765 adults sustaining major trauma, 72 942 (51.09 %) had long bone or pelvic fractures and 45.81% of these were > 65 years old. Road traffic collision was the most common mechanism in the young (40.4%) and, in older people, fall from standing height (80.4%) predominated. The 30 day mortality in older patients with fractures is greater (6.8% versus 2.5%), although critical care episodes are more common in the young (18.2% versus 9.7%). Older people are less likely to be admitted to critical care beds and are often managed in isolation by surgeons. Orthopaedic surgery is the most common admitting and operating specialty and, in older people, fracture surgery accounted for 82.1% of procedures. . Conclusion. Orthopaedic trauma in older people is associated with mortality that is significantly greater than for similar fractures in the young. As with the hip fracture population, major trauma in the elderly is a growing concern which highlights the need for a review of admission pathways and shared orthogeriatric care models. .

Aims. This study aims to estimate economic outcomes associated with 30-day deep surgical site infection (SSI) from closed surgical wounds in patients with lower limb fractures following major trauma. Methods. Data from the Wound Healing in Surgery for Trauma (WHiST) trial, which collected outcomes from 1,547 adult participants using self-completed questionnaires over a six-month period following major trauma, was used as the basis of this empirical investigation. Associations between deep SSI and NHS and personal social services (PSS) costs (£, 2017 to 2018 prices), and between deep SSI and quality-adjusted life years (QALYs), were estimated using descriptive and multivariable analyses. Sensitivity analyses assessed the impact of uncertainty surrounding components of the economic analyses. Results. Compared to participants without deep SSI, those with deep SSI had higher mean adjusted total NHS and PSS costs (adjusted mean difference £1,577 (95% confidence interval (CI) -951 to 4,105); p = 0.222), and lower mean adjusted QALYs (adjusted mean difference -0.015 (95% CI -0.032 to 0.002); p = 0.092) over six months post-injury, but this difference was not statistically significant. The results were robust to the sensitivity analyses performed. Conclusion. This study found worse economic outcomes during the first six months post-injury in participants who experience deep SSI following orthopaedic surgery for major trauma to the lower limb. However, the increase in cost associated with deep SSI was less than previously reported in the orthopaedic trauma literature. Cite this article: Bone Jt Open 2022;3(5):398–403

Following the establishment of regional Major Trauma Networks in England in 2012, there were concerns that pressures regarding resource allocation in Major Trauma Centres (MTCs) may have a detrimental impact on the care of patients with hip fractures in these hospitals. This study aimed to compare outcomes in hip fracture care between MTCs and trauma units (TUs). National Hip Fracture Database data was extracted from 01/01/2015 to 31/12/2022 for all hospitals in England. Outcome measures included perioperative medical and physiotherapy assessments, time to surgery, consultant supervision in theatre, Best Practice Tariff (BPT) compliance, discharge to original residence, and mortality. Data was pooled and weighted for MTCs and remaining hospitals (TUs). A total of 487,089 patients with hip fractures were included from 167 hospitals (23 MTCs and 144 TUs). MTCs achieved marginally higher rates of orthogeriatrician assessment within 72 hours of admission (91.1% vs 90.4%, p<0.001) and mobilisation out of bed by first postoperative day (81.9% vs 79.7%, p<0.001). A lower proportion of patients underwent surgery by the day after admission in MTCs (65.2% vs 69.7%, p<0.001). However, there was significantly higher consultant surgeon and anaesthetist supervision rates during surgery in MTCs (71.8% vs 61.6%, p<0.001). There was poorer compliance with BPT criteria in MTCs (57.3% vs 60.4%, p<0.001), and proportionately fewer MTC patients were discharged to their original residence (63.5% vs 60.4%, p<0.001). There was no difference between MTCs and TUs in 30-day mortality (6.8% vs 6.8%, p=0.825). This study demonstrates that MTCs have greater difficulty in providing prompt surgery to hip fracture patients. However, their marginally superior perioperative care outcomes appear to compensate for this, as their mortality rates are similar to TUs. These findings suggest that the regionalisation of major trauma in England has not significantly compromised the overall care of hip fracture patients

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

Introduction: Little is known about the epidemiology of spinal injuries in large major trauma populations. The aim of this study, therefore, is to describe mechanisms of injury, patient and injury characteristics and outcomes following spinal injuries in major trauma patients. Methods: Data was extracted from the State Trauma Registry for Victoria (population 4.6 million) on all patients registered between 1 July 2001 and 31 June 2003 with spinal injuries and an Injury Severity Score (ISS) > 15. Injuries were defined using Abbreviated Injury Score (AIS) codes. Major trauma patients with spinal injuries were compared with those without spinal injuries with respect to age, gender, ISS scores, mechanism of injury, number and site of spinal and associated injuries, acute length of stay and discharge destination. Results: 2194 major trauma patients were identified, of which 548 (25%) had spinal injuries. Spinal injuries occurred in 412 males (75%) and 136 females (25%), with a median age of 36 years (range 2–94 years). There was no difference in age or gender compared with patients with no spinal injury. 316 patients (58%) had multiple spinal injuries. 22% of patients with spinal injuries had associated spinal cord injuries. Most spinal fractures occurred and were more likely to occur as the result of motor vehicle (46%) or motorcycle (16%) crashes or falls from heights greater than 1 metre (15%). The median ISS score was 24 (range 16–75) and not significantly different from patients with no spinal injury. The median number of associated injuries was 5 (range 0–23) and patients with spinal injuries were more likely to have associated thoracic, abdominal and extremity injuries and less likely to have associated head injuries than patients with no spinal injury. Patients with spinal injuries were more likely to be discharged to rehabilitation or convalescent hospitals and less likely to die than patients with no spinal injury. Discussion: Spinal injuries are common and often multiple in major trauma patients and are associated with a greater need for rehabilitation. Further studies are required to determine the impact of spinal injuries on the functional outcomes of major trauma patients

Aims. The new COVID-19 variant was reported by the authorities of the UK to the World Health Organization (WHO) on 14 December 2020. We aim to describe the clinical characteristics and nosocomial infection rates in major trauma and orthopaedic patients comparing the first and second wave of COVID-19 infection. Methods. A retrospective analysis of a prospectively collected trauma database was reviewed at a level 1 major trauma centre from 1 December 2020 to 18 February 2021 looking at demographics, clinical characteristics, and nosocomial infections and compared to our previously published first wave data (26 January 2020 to 14 April 2020). Results. From 1 December 2020 to 18 February 2021, 522 major trauma patients were identified with a mean age of 54.6 years, and 53.4% (n = 279) were male. Common admissions were falls (318; 60.9%) and road traffic accidents (RTAs; 71 (13.6%); 262 of these patients (50.2%) had surgery. In all, 75 patients (14.4%) tested positive for COVID-19, of which 51 (68%) were nosocomial. Surgery on COVID-19 patients increased to 46 (61.3%) in the second wave compared to 13 (33.3%) in the first wave (p = 0.005). ICU admissions of patients with COVID-19 infection increased from two (5.1%) to 16 (20.5%), respectively (p = 0.024). Second wave mortality was 6.1% (n = 32) compared to first wave of 4.7% (n = 31). Cardiovascular (CV) disease (35.9%; n = 14); p = 0.027) and dementia (17.9%; n = 7); p = 0.030) were less in second wave than the first. Overall, 13 patients (25.5%) were Black, Asian and Minority ethnic (BAME), and five (9.8%) had a BMI > 30 kg/m. 2. The mean time from admission to diagnosis of COVID-19 was 13.9 days (3 to 44). Overall, 12/75 (16%) of all COVID-19 patients died. Conclusion. During the second wave, COVID-19 infected three-times more patients. There were double the number of operative cases, and quadruple the cases of ICU admissions. The patients were younger with less dementia and CV disease with lower mortality. Concomitant COVID-19 and the necessity of major trauma surgery showed 13% mortality in the second wave compared with 15.4% in the first wave. In contrast to the literature, we showed a high percentage of nosocomial infection, normal BMI, and limited BAME infections. Cite this article: Bone Jt Open 2021;2(8):661–670

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

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

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

Aims. The first death in the UK caused by COVID-19 occurred on 5 March 2020. We aim to describe the clinical characteristics and outcomes of major trauma and orthopaedic patients admitted in the early COVID-19 era. Methods. A prospective trauma registry was reviewed at a Level 1 Major Trauma Centre. We divided patients into Group A, 40 days prior to 5 March 2020, and into Group B, 40 days after. Results. A total of 657 consecutive trauma and orthopaedic patients were identified with a mean age of 55 years (8 to 98; standard deviation (SD) 22.52) and 393 (59.8%) were males. In all, 344 (approximately 50%) of admissions were major trauma. Group A had 421 patients, decreasing to 236 patients in Group B (36%). Mechanism of injury (MOI) was commonly a fall in 351 (52.4%) patients, but road traffic accidents (RTAs) increased from 56 (13.3%) in group A to 51 (21.6%) in group B (p = 0.030). ICU admissions decreased from 26 (6.2%) in group A to 5 (2.1%) in group B. Overall, 39 patients tested positive for COVID-19 with mean age of 73 years (28 to 98; SD 17.99) and 22 (56.4%) males. Common symptoms were dyspnoea, dry cough, and pyrexia. Of these patients, 27 (69.2%) were nosocomial infections and two (5.1%) of these patients required intensive care unit (ICU) admission with 8/39 mortality (20.5%). Of the patients who died, 50% were older and had underlying comorbidities (hypertension and cardiovascular disease, dementia, arthritis). Conclusion. Trauma admissions decreased in the lockdown phase with an increased incidence of RTAs. Nosocomial infection was common in 27 (69.2%) of those with COVID-19. Symptoms and comorbidities were consistent with previous reports with noted inclusion of dementia and arthritis. The mortality rate of trauma and COVID-19 was 20.5%, mainly in octogenarians, and COVID-19 surgical mortality was 15.4%. Cite this article: Bone Joint Open 2020;1-7:330–338

Introduction. Despite the established guidelines on lower extremity free flap reconstruction by the British Orthopaedic Association Standard for Trauma (BOAST-4) the post-operative care has yet to be standardised. There is currently no coherent evidence in the literature regarding clinical monitoring, warming, dangling and compression; the optimal regimes and their respective physiological benefits. The aim of this study is to survey all UK Major Trauma Centres (MTCs) with regards to the post-operative care of lower extremity free flaps and elucidate the current protocols for clinical monitoring, warming, dangling and compression. Materials & Methods. All UK-based adult MTCs were surveyed. We formulated a detailed questionnaire to enquire about the post-operative care of lower extremity free flap reconstructions; the number of free flap reconstructions per month and take backs per month and for which post-operative methods a protocol is used in each MTC. We asked specific questions concerning: clinical monitoring, warming, dangling and compression. This questionnaire was distributed to consultant leads in the form of multiple choice questions, with an option of free-text box for further comments, using JISC online surveys. Results were analysed in Excel and presented in percentages. Results. The 28 adult MTCs were contacted. The results showed a lack of formal regional protocols with great variability, suggesting there is no general consensus on post-operative care of lower extremity free flap reconstructions with regards to clinical monitoring, warming, dangling and compression. Conclusions. This survey of UK MTCs on the post-operative protocols for lower extremity free flap reconstruction demonstrated lack of evidence, consensus and large variability in common practice which requires standardisation

Introduction: Elevated plasma elastase levels have been reported following major trauma and isolated femoral fracture. Reamed femoral nailing has been shown to further increase plasma elastase levels. The aim of this study was to investigate neutrophil (PMN) priming for degranulation following major trauma and isolated long-bone pelvis fracture by assessing the ability of PMN to release elastase in-vitro in response to phorbol myristate acetate (PMA) an analogue of dia-cylglycerol (DAG) a component of the “second messenger” system. Methods: 11 major trauma (ISS≥18) patients and 18 patients with isolated long-bone/pelvis fracture, were consented to enter the study. Patients in the isolated fracture group were further stratified depending upon the type of fracture stabilization they underwent [reamed nail (n=12), Ex-Fix (n=6)]. Blood samples were obtained on admission, at 24 hours post injury, at day 3 and day 5. 11 healthy volunteers were used as controls. PMN were isolated by dextran sedimentation and ficoll-hypaque density gradient centrifugation. The ability of PMN to degranulate was assessed by an elastase substrate assay. Results: A significant increase in the capacity of PMN to release elastase in response to a PMA stimulus was seen in major trauma patients on admission as compared with healthy volunteers. However in patients with isolated long-bone/pelvis fracture, there was no difference in levels of elastase release. Further no difference in the ability of PMN to release elastase was seen between the reamed nail and Ex-Fix groups. Conclusions: In conclusion we show that PMN are primed for increased degranulation (elastase release) following major trauma but not following isolated long-bone/pelvis fracture. These primed PMN are capable of increased tissue damage following major trauma thus increasing the risk of development of multiple organ failure

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

Despite increasing use of vena cava filters (VCFs) for pulmonary embolism (PE) prophylaxis after major trauma, there is continued debate regarding their safety and efficacy. We aimed to evaluate the impact of prophylactic VCFs on the incidence of PE after major trauma and to describe VCF related complications. Prospectively collected data from The Alfred Hospital Trauma Registry were used to identify all major trauma patients admitted between 1 July 2001 and 1 July 2008. Data for each patient was collated from the registry. This included patient demographics, injury specific data, management details (including prophylactic VCF use) and clinical outcomes (including the occurrence of PE). Medical record and radiology chart review was used to verify all PEs. Potential PE risk factors were assessed as covariates in a univariate analysis, with PE as the dependent variable. A multivariate analysis was then performed using multiple logistic regression adjusting for baseline imbalances and known covariates. During this period, 6,344 major trauma patients were treated, with 73.2% male, mean age of 44.2 +/− 21.0 SD, 90.2% with a blunt mechanism of injury and mean ISS of 24.3 +/− 12.0 SD. Of these patients, 511 (8.1%) received prophylactic VCFs, (inserted in absence of PE) at the discretion of the treating clinician. There were 45 PE (incidence of 0.71%), of which two were fatal. Three variables were independently associated with the occurrence of PE in the multivariate analysis: (i) presence of prophylactic VCF (OR 0.28; 95%CI 0.09 - 0.89); (ii) number of injuries to the AIS body region lower limb (OR 1.31; 95%CI 1.17 - 1.47) and (iii) central venous catheterisation (OR 1.87; 95%CI 1.88 - 6.17). Data was available on the VCF database for 429 of the 511 patients with VCFs (84.0%). The mean time to prophylactic VCF insertion was 3.6 +/− 0.2 SEM days after admission. The VCF major complication rate was 2.6% (n=11), including four non-fatal PE. The technical success rate for retrieval was 92.4% (279 retrievals from 302 attempts) and the overall retrieval rate was 65.0% (279 retrievals from 429 placements). Prophylactic VCFs are associated with a reduced rate of PE when used in selected major trauma patients. In addition, prophylactic VCFs have a low major complication rate and high rate of technical success for retrieval

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

This study examined spinal fractures in patients admitted to a Major Trauma Centre via two independent pathways, a major trauma (MT) pathway and a standard unscheduled non-major trauma (NMT) pathway. A total of 134 patients were admitted with a spinal fracture over a period of two years; 50% of patients were MT and the remainder NMT. MT patients were predominantly male, had a mean age of 48.8 years (13 to 95), commonly underwent surgery (62.7%), characteristically had fractures in the cervico-thoracic and thoracic regions and 50% had fractures of more than one vertebrae, which were radiologically unstable in 70%. By contrast, NMT patients showed an equal gender distribution, were older (mean 58.1 years; 12 to 94), required fewer operations (56.7%), characteristically had fractures in the lumbar region and had fewer multiple and unstable fractures. This level of complexity was reflected in the length of stay in hospital; MT patients receiving surgery were in hospital for a mean of three to four days longer than NMT patients. These results show that MT patients differ from their NMT counterparts and have an increasing complexity of spinal injury. Cite this article: Bone Joint J 2015;97-B:235–9
