Traumatic native hip dislocation in the absence of acetabular or femoral fracture in adults: a retrospective study reporting clinical and radiological outcomes from a major trauma centre in the United Kingdom.

INTRODUCTION: Posterior native hip dislocations (NHD) are high-energy injuries. Thompson-Epstein Type I dislocations describe those without significant associated femoral or acetabular fracture. The aim of this study was to compare the clinical and radiological outcomes of patients with Type I NHDs. We also evaluate the association between radiological indicators of femoroacetabular impingement (FAI) and NHD. PATIENTS AND METHODS: A retrospective study from January 2012 to May 2021 compared skeletally mature patients (⩾16 years) with Type I posterior NHD to age and gender-matched controls with Type II-V posterior NHD. Patient demographics, mechanism of injury, complications and patient-reported outcome measures (PROMs) are presented. Post reduction radiographs and computed tomography were used to assess for FAI. Univariate analyses were performed to evaluate radiological outcomes. RESULTS: 13 patients (77% male) with Type I posterior NHD were compared to a control group of 40 patients (80% male) with Type II-V posterior NHD. 11 patients in the study group and 14 in the control group experienced isolated injuries (p = 0.01). Post-reduction complications were similar. The study group had significantly lower post-injury osteoarthritis incidence (n = 0) compared to controls (n = 18, p = 0.0083). Patients reported a mean Oxford Hip Score of 43.5 ± 2.2 and EQ-5D-VAS score of 87.1 ± 7.4, with 6 patients indicating minimal symptoms across all EQ-5D-5L domains. Radiological femoroacetabular impingement (FAI) was prevalent in both groups, especially among males. CONCLUSIONS: Patients who underwent emergent closed reduction of Type I NHD demonstrated good short to medium term outcomes. Our radiological findings suggest a high prevalence of FAI. Future work should aim to quantify longer term outcomes following this injury. We call for further comparative studies of patients who suffer NHD with and without fractures to aid our understanding of risk factors. Given the rarity of this injury, multicentre efforts will be required to capture large numbers of patients.

Following hip fracture, hospital organizational factors associated with prescription of anti-osteoporosis medication on discharge, to address imminent refracture risk: a record-linkage study.

Patients who sustain a hip fracture are known to be at imminent refracture risk. Their complex multidisciplinary rehabilitation needs to include falls prevention and anti-osteoporosis medication (AOM) to prevent such fractures. This study aimed to determine which hospital-level organizational factors predict prescription of post-hip fracture AOM and refracture risk. A cohort of 178 757 patients aged ≥60 yr who sustained a hip fracture in England and Wales (2016-2019) was examined and followed for 1 yr. Patient-level hospital admission datasets from 172 hospitals, the National Hip Fracture Database, and mortality data were linked to 71 metrics extracted from 18 hospital-level organizational reports. Multilevel models determined organizational factors, independent of patient case-mix, associated with (1) AOM prescription and (2) refracture (by ICD10 coding). Patients were mean (SD) 82.7 (8.6) yr old, 71% female, with 18% admitted from care homes. Overall, 101 735 (57%) were prescribed AOM during admission, while 50 354 (28%) died during 1-yr follow-up, 12 240 (7%) refractured. Twelve organizational factors were associated with AOM prescription, for example, orthogeriatrician-led care compared to traditional care models (odds ratio [OR] 4.65 [95% CI, 2.25-9.59]); AOM was 9% (95% CI, 6%-13%) more likely to be prescribed in hospitals providing routine bone health assessment to all patients. Refracture occurred at median 126 d (IQR 59-234). Eight organizational factors were associated with refracture risk; hospitals providing orthogeriatrician assessment to all patients within 72 h of admission had an 18% (95% CI, 2%-31%) lower refracture risk, weekend physiotherapy provision had an 8% (95% CI, 3%-14%) lower risk, and where occupational therapists attended clinical governance meetings, a 7% (95% CI, 2%-12%) lower risk. Delays initiating post-discharge community rehabilitation were associated with a 15% (95% CI, 3%-29%) greater refracture risk. These novel, national findings highlight the importance of orthogeriatrician, physiotherapist, and occupational therapist involvement in secondary fracture prevention post hip fracture; notably, fracture risk reductions were seen within 12 mo of hip fracture.

Patients who have broken (fractured) a hip are at risk of having another fracture soon after. They have complex needs to avoid more fractures, which include being prescribed bone-strengthening medicines and taking measures to prevent falls. This study looked at which of the measurements, that describe how well a hospital is organized, are associated with whether bone-strengthening medicine is prescribed and the chance of having another fracture. We used data from 178 757 patients aged over 60 yr who had a hip fracture at 172 English and Welsh hospitals, linked to their hospital records, and other datasets that describe hospital services. Overall, 57% of patients were prescribed bone-strengthening medicines, and 7% went on to have another fracture. Bone-strengthening medicines were more likely to be prescribed in hospitals where patient care was led by a consultant specializing in the care of older people with fractures (called orthogeriatricians) and in hospitals which routinely checked patients' bone health. Patients attending hospitals that provided orthogeriatrician assessment to all patients within 72 h of being admitted, physiotherapy services at the weekend, or where occupational therapists attended meetings aimed at improving hospital services had a lower chance of having another fracture.

Radiological outcomes following surgical fixation with wires versus moulded cast for patients with a dorsally displaced fracture of the distal radius: a radiographic analysis from the DRAFFT2 trial.

Aims: The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury. Methods: Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient's initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed. Results: Patients treated with surgical fixation with wires had less dorsal angulation of the radius versus those treated in a moulded cast at six weeks after manipulation of the fracture; the mean difference of -4.13° was statistically significant (95% confidence interval 5.82 to -2.45). There was no evidence of a difference in radial shortening. However, there was no correlation between these radiological measurements and PROMs at any timepoint in the 12 months post-injury. Conclusion: For patients with a dorsally displaced distal radius fracture treated with a closed manipulation, surgical fixation with wires leads to less dorsal angulation on radiographs at six weeks compared with patients treated in a moulded plaster cast alone. However, the difference in dorsal angulation was small and did not correlate with patient-reported pain and function.

Fewer native and periprosthetic femoral fracture patients receive an orthogeriatric review and expedited surgery compared to hip fracture patients.

INTRODUCTION: Disproportionate emphasis has been attributed to hip fracture over other femoral fractures through implementation of Best Practice Tariff (BPT).This retrospective comparative observational cohort study aimed to evaluate the epidemiology of native and periprosthetic femoral fractures and establish any disparities in their management relative to hip fractures. METHODS: All patients ⩾60 years admitted with a native or periprosthetic femoral fracture during July 2016-June 2018 were identified using our hospital database. Results were compared to National Hip Fracture Database data over the same period. RESULTS: 58 native femoral, 87 periprosthetic and 1032 hip fractures were identified. (46/58) 79% and 76/87 (89%) of native and periprosthetic femoral fractures were managed operatively. Surgery was performed <36 hours for 34/46 (74%) of native femoral and 33/76 (43%) of periprosthetic fractures compared to 826/1032 (80%) for hips. Median time to surgery was longer in periprosthetic femoral than hip fracture patients (44.7 vs. 21.6 hours; p < 0.0001). Orthogeriatrician review occurred in 24/58 (41%) and 48/87 (55%) of native and periprosthetic fractures compared to 1017/1032 (99%) for hips (p < 0.0001). One year mortality was 35%, 20% and 26% for native femoral, periprosthetic and hip fracture patients. Cox proportional hazard ratio was higher for native femoral than hip fracture patients (1.75; 95% CI, 1.12-2.73). CONCLUSIONS: This study demonstrates large disparities in management of other femoral and periprosthetic fractures compared to hip fractures, specifically time to surgery and orthogeriatrician review. This may have resulted in the comparatively higher mortality rate of native femoral fracture patients. Expansion of the BPT to include the whole femur is likely to improve outcomes.

Organisational factors associated with hospital costs and patient mortality in the 365 days following hip fracture in England and Wales (REDUCE): a record-linkage cohort study.

BACKGROUND: Hip fracture care delivery varies between hospitals, which might explain variations in patient outcomes and health costs. The aim of this study was to identify hospital-level organisational factors associated with long-term patient outcomes and costs after hip fracture. METHODS: REDUCE was a record-linkage cohort study in which national databases for all patients aged 60 years and older who sustained a hip fracture in England and Wales were linked with hospital metrics from 18 organisational data sources. Multilevel models identified organisational factors associated with the case-mix adjusted primary outcomes: cumulative all-cause mortality, days spent in hospital, and inpatient costs over 365 days after hip fracture. FINDINGS: Between April 1, 2016, and March 31, 2019, 178 757 patients with an index hip fracture were identified from 172 hospitals in England and Wales. 126 278 (70·6%) were female, 52 479 (29·4%) were male, and median age was 84 years (IQR 77-89) in England and 83 years (77-89) in Wales. 365 days after hip fracture, 50 354 (28·2%) patients had died. Patients spent a median 21 days (IQR 11-41) in hospital, incurring costs of £14 642 (95% CI 14 600-14 683) per patient, ranging from £10 867 (SD 5880) to £23 188 (17 223) between hospitals. 11 organisational factors were independently associated with mortality, 24 with number of days in hospital, and 25 with inpatient costs. Having all patients assessed by an orthogeriatrician within 72 h of admission was associated with a mean cost saving of £529 (95% CI 148-910) per patient and a lower 365-day mortality (odds ratio 0·85 [95% CI 0·76-0·94]). Consultant orthogeriatrician attendance at clinical governance meetings was associated with cost savings of £356 (95% CI 188-525) and 1·47 fewer days (95% CI 0·89-2·05) in the hospital in the 365 days after hip fracture per patient. The provision of physiotherapy to patients on weekends was associated with a cost saving of £676 (95% CI 67-1285) per patient and with 2·32 fewer days (0·35-4·29) in hospital in the 365 days after hip fracture. INTERPRETATION: Multiple, potentially modifiable hospital-level organisational factors associated with important clinical outcomes and inpatient costs were identified that should inform initiatives to improve the effectiveness and efficiency of hip fracture services. FUNDING: Versus Arthritis.

Patients' recovery of mobility and return to original residence after hip fracture are associated with multiple modifiable components of hospital service organisation: the REDUCE record-linkage cohort study in England and Wales.

BACKGROUND: Hip fractures are devastating injuries causing disability, dependence, and institutionalisation, yet hospital care is highly variable. This study aimed to determine hospital organisational factors associated with recovery of mobility and change in patient residence after hip fracture. METHODS: A cohort of patients aged 60 + years in England and Wales, who sustained a hip fracture from 2016 to 2019 was examined. Patient-level Hospital Episodes Statistics, National Hip Fracture Database, and mortality records were linked to 101 factors derived from 18 hospital-level organisational metrics. After adjustment for patient case-mix, multilevel models were used to identify organisational factors associated with patient residence at discharge, and mobility and residence at 120 days after hip fracture. RESULTS: Across 172 hospitals, 165,350 patients survived to discharge, of whom 163,230 (99%) had post-hospital discharge destination recorded. 18,323 (11%) died within 120 days. Among 147,027 survivors, 58,344 (40%) across 143 hospitals had their residence recorded, and 56,959 (39%) across 140 hospitals had their mobility recorded, at 120 days. Nineteen organisational factors independently predicted residence on hospital discharge e.g., return to original residence was 31% (95% confidence interval, CI:17-43%) more likely if the anaesthetic lead for hip fracture had time allocated in their job plan, and 8-13% more likely if hip fracture service clinical governance meetings were attended by an orthopaedic surgeon, physiotherapist or anaesthetist. Seven organisational factors independently predicted residence at 120 days. Patients returning to their pre-fracture residence was 26% (95%CI:4-42%) more likely if hospitals had a dedicated hip fracture ward, and 20% (95%CI:8-30%) more likely if treatment plans were proactively discussed with patients and families on admission. Seventeen organisational factors predicted mobility at 120 days. More patients re-attained their pre-fracture mobility in hospitals where (i) care involved an orthogeriatrician (15% [95%CI:1-28%] improvement), (ii) general anaesthesia was usually accompanied by a nerve block (7% [95%CI:1-12%], and (iii) bedside haemoglobin testing was routine in theatre recovery (13% [95%CI:6-20%]). CONCLUSIONS: Multiple, potentially modifiable, organisational factors are associated with patient outcomes up to 120 days after a hip fracture, these factors if causal should be targeted by service improvement initiatives to reduce variability, improve hospital hip fracture care, and maximise patient independence.

Posterior pelvic ring involvement detected with CT taken within a week of admission in acute fragility fractures of the pelvis (FFP) does not predict failure of conservative treatment: a retrospective cohort study.

BACKGROUND: Acute low energy pubic rami fractures in the elderly receive primarily conservative treatment. There is debate to what extent posterior ring involvement, which is detected superiorly by CT compared to X-ray, has an impact on outcome and may require modified treatment. We want to demonstrate if posterior ring involvement has an influence on different types of outcome in primarily conservatively treated acute FFP, questioning the usefulness of early CT. Additionally we analysed the early fracture pattern in cases where conservative treatment failed with need for secondary surgery. METHODS: A retrospective cohort study of 155 consecutive patients, recruited between 2009 and 2016, aged over 65 years diagnosed with an acute LE-PFr on X-ray at the emergency department of a single, level-one trauma centre and receiving an early CT. A set of outcome parameters was compared between patients with an isolated pubic rami fracture (CTia) and patients who had a combined posterior pelvic ring fracture (CTcp). RESULTS: There were 155 patients of whom 85.2% were female with a mean age of 83 years. 76.8% of patients living at home returned home and 15.5% moved to a nursing home. Mortality rate during hospitalisation was 6.4% and 14.8% at one year post-trauma. Secondary fracture displacement occurred in 22.6%. Secondary surgery was performed in 6 cases (3.9%). Median hospitalisation length of stay was 21 days (range 0 to 112 days). There was no significant association between the subgroups and change in residential status (p = 0.65), complications during hospitalisation (p = 0.75), mortality rate during admission (p = 0.75) and at 1 year (p = 0.88), readmission within 30 days (p = 0.46) and need for secondary surgery (p = 0.2). There was a significant increased median length of stay (p = 0.011) and rate of secondary displacement (p = 0.015) in subgroup CTcp. Secondary displacement had no impact on in-hospital complications (p = 0.7) nor mortality rate during admission (p = 0.79) or at 1 year (0.77). Early CT in patients who underwent secondary surgery showed stable B2.1 lesions in 4 of 6 cases. CONCLUSIONS: Our data suggest that early CT in patients with conservatively treated acute LE-PFr in order to detect posterior lesions, has limited value in predicting failure of conservative treatment.

Mid-term results of the treatment of complex acetabular fractures with combined acute fixation and total hip replacement in the older patient.

INTRODUCTION: The incidence of acetabular fractures in older patients is increasing. The management of these patients is evolving due to the recognition of risks associated with prolonged immobility with conservative treatment. MATERIALS AND METHODS: Consecutive patients undergoing fixation and total hip replacement (THR) for displaced acetabular fractures undergoing single operation with acetabular fixation and THR were identified. Outcomes were assessed using radiographs, clinical notes, Oxford Hip Score and EuroQol-5L. RESULTS: 77 patients were identified with 51 completing outcome scores. Mean age 68 years at time of injury. Mean follow-up 5 (2-12) years, OHS 40, EQ-5D 0.78. Revision surgery performed in 7 patients (9%). DISCUSSION: Acute fixation combined with THR for acetabular fractures in the elderly patient, offers good functional outcomes and a low complication rate in the mid-term.

The fate of acetabular fracture fixation at 10 years: rates of conversion to arthroplasty.

BACKGROUND: Post-traumatic arthritis, implant failure, non-union or avascular necrosis may result in a total hip arthroplasty (THA) after acetabular fracture fixation (AFF). The aim of this study was to report the occurrence of THA after AFF and analyse factors that predict its occurrence. PATIENTS AND METHODS: All patients with AFF between 2010 and 2014, in a major trauma centre, were included. Patients treated conservatively or with acute THA were excluded. Data regarding classification of fracture, details of surgery and follow-up using EQ-5D and Oxford Hip Score (OHS) were recorded prospectively. Postoperative radiographs and CT scans were analysed for accuracy of reduction. The number of patients who underwent secondary THA and indications were recorded. RESULTS: 122 patients with a mean age of 42 years were included. At a mean follow-up of 10 years, the mean OHS was 39 (range 22-48) and EQ-5D was 22 (range 10-25). THA was performed in 10 patients (8%), 50% of which were performed between 2-5 years after AFF. Age >40 years, posterior dislocation and presence of posterior wall fracture, were the only factors associated with progression to THA. The survivorship of fixation at 5 years was 95% (95% CI, 91-98%) and at 10 years was 91% (95% CI, 86-96%). CONCLUSIONS: Conversion to THA after AFF was 8%, with even anatomically reduced posterior wall fractures having a poor prognosis. A period of follow-up of at least 5 years is suggested in patients with risk factors.

Multiple hospital organisational factors are associated with adverse patient outcomes post-hip fracture in England and Wales: the REDUCE record-linkage cohort study.

OBJECTIVES: Despite established standards and guidelines, substantial variation remains in the delivery of hip fracture care across the United Kingdom. We aimed to determine which hospital-level organisational factors predict adverse patient outcomes in the months following hip fracture. METHODS: We examined a national record-linkage cohort of 178,757 patients aged ≥60 years who sustained a hip fracture in England and Wales in 2016-19. Patient-level hospital admissions datasets, National Hip Fracture Database and mortality data were linked to metrics from 18 hospital-level organisational-level audits and reports. Multilevel models identified organisational factors, independent of patient case-mix, associated with three patient outcomes: length of hospital stay (LOS), 30-day all-cause mortality and emergency 30-day readmission. RESULTS: Across hospitals mean LOS ranged from 12 to 41.9 days, mean 30-day mortality from 3.7 to 10.4% and mean readmission rates from 3.7 to 30.3%, overall means were 21.4 days, 7.3% and 15.3%, respectively. In all, 22 organisational factors were independently associated with LOS; e.g. a hospital's ability to mobilise >90% of patients promptly after surgery predicted a 2-day shorter LOS (95% confidence interval [CI]: 1.2-2.6). Ten organisational factors were independently associated with 30-day mortality; e.g. discussion of patient experience feedback at clinical governance meetings and provision of prompt surgery to >80% of patients were each associated with 10% lower mortality (95%CI: 5-15%). Nine organisational factors were independently associated with readmissions; e.g. readmissions were 17% lower if hospitals reported how soon community therapy would start after discharge (95%CI: 9-24%). CONCLUSIONS: Receipt of hip fracture care should be reliable and equitable across the country. We have identified multiple, potentially modifiable, organisational factors associated with important patient outcomes following hip fracture.

Epidemiology and outcomes of tibial plateau fractures in adults aged 60 and over treated in the United Kingdom.

BACKGROUND: Tibial plateau fractures are common in older adults, often resulting from low-energy falls. Although lower limb fragility fracture care has evolved, the management of tibial plateau fractures in older patients remains poorly researched. This study aimed to define the epidemiology, treatment and outcomes of tibial plateau fractures in patients aged over 60 years. METHODOLOGY: Patients aged 60 years or older with a tibial plateau fracture who presented to a single trauma center between January 2008 and December 2018 were identified. Incomplete records were excluded. Epidemiological data, fracture classification, injury management, radiological outcomes, complications, and mortality were assessed via retrospective case note and radiograph review. Local ethics approval was obtained. RESULTS: Two-hundred and twenty patients with a mean age of 74 years (range 60-100) were included. 73% were female and 71% of injuries were sustained following low-energy falls. Median follow up was three months. 50% of fractures involved the lateral plateau. 60% of injuries were treated non-operatively. 76% of patients had their weight-bearing restricted for the first six weeks, with little difference between operatively and non-operatively managed patients. 8% of all patients required subsequent knee replacement. All-cause mortality at 30-days and one-year were 2% and 5% respectively. CONCLUSION: The majority of tibial plateau fractures in the over 60s are sustained from low-energy trauma. Management is relatively conservative when compared with younger cohorts. The data reported brings up questions of whether surgical treatment is beneficial to this patient group, or whether restricted weight bearing is either possible or beneficial. Prospective, multi-center comparative trials are needed to determine whether increased operative intervention or different rehabilitation strategies purveys any patient benefit.

Reducing unnecessary fixation of midshaft clavicle fractures.

PURPOSE: Displaced midshaft clavicle fractures have a non-union rate of 10-20%. Those who unite with conservative treatment have similar outcomes to those who undergo operative treatment; therefore, protocols to identify potential non-unions are important to avoid unnecessary surgery. The aim of this study is to report one such protocol. METHODS: A protocol was introduced, where all isolated closed displaced midshaft clavicle fractures were initially managed non-operatively in a sling. At 2 weeks patients were assessed clinically and those who were struggling with their symptoms were offered surgery, with the remainder mobilised as comfortable. All cases treated at one centre over a three-year period, with a minimum follow-up of one-year underwent case note review. RESULTS: Between 2015 and 2017 613 clavicle fractures were managed through clinic. 347 were middle third (56%), 75% were male, mean age 41(range16-97). Forty-one middle third clavicle fracture patients underwent early fixation. Eleven patients required late fixation for symptomatic delayed, non- or malunion, 6 for symptomatic non-unions and 1 was a symptomatic malunion. For displaced fractures the early operative rate was 17.8%, and symptomatic non/malunion rate was 3.2%. This led to a total operative rate of 21%. CONCLUSION: A protocol for managing clavicle fractures has demonstrated an effective management of these injuries. It is cost-effective reducing the number of patients with displaced fractures requiring fixation with a fixation rate of 21% whilst reducing the rate of symptomatic non- and malunion (3.2%). The management pathway is simple and could be introduced into any orthopaedic outpatient department with ease.

REducing unwarranted variation in the Delivery of high qUality hip fraCture services in England and Wales (REDUCE): protocol for a mixed-methods study.

INTRODUCTION: Substantial variation in the delivery of hip fracture care, and patient outcomes persists between hospitals, despite established UK national standards and guidelines. Patients' outcomes are partly explained by patient-level risk factors, but it is hypothesised that organisational-level factors account for the persistence of unwarranted variation in outcomes. The mixed-methods REducing unwarranted variation in the Delivery of high qUality hip fraCture services in England and Wales (REDUCE) study, aims to determine key organisational factors to target to improve patient care. METHODS AND ANALYSIS: Quantitative analysis will assess the outcomes of patients treated at 172 hospitals in England and Wales (2016-2019) using National Hip Fracture Database data combined with English Hospital Episodes Statistics; Patient Episode Database for Wales; Civil Registration (deaths) and multiple organisational-level audits to characterise each service provider. Statistical analyses will identify which organisational factors explain variation in patient outcomes, and typify care pathways with high-quality consistent patient outcomes. Documentary analysis of 20 anonymised British Orthopaedic Association hospital-initiated peer-review reports, and qualitative interviews with staff from four diverse UK hospitals providing hip fracture care, will identify barriers and facilitators to care delivery. The COVID-19 pandemic has posed a major challenge to the resilience of services and interviews will explore strategies used to adapt and innovate. This system-wide understanding will inform the development, in partnership with key national stakeholders, of an 'Implementation Toolkit' to inform and improve commissioning and delivery of hip fracture services. ETHICS AND DISSEMINATION: This study was approved: quantitative study by London, City and East Research Ethics Committee (20/LO/0101); and qualitative study by Faculty of Health Sciences University of Bristol Research Ethics Committee (Ref: 108284), National Health Service (NHS) Health Research Authority (20/HRA/71) and each NHS Trust provided Research and Development approval. Findings will be disseminated through scientific conferences, peer-reviewed journals and online workshops.

Current concepts: managing acetabular fractures in the elderly population.

The aim of this review is to summarise the current concepts in the management of acetabular fractures in the elderly population. A literature review of the evidence regarding the management of elderly acetabular fractures was performed utilising PubMed and Ovid. The predominant causes and fracture patterns of acetabular fractures are changing as populations age. Consequently, the operative management has had to change also. Judet and LeTournel did not offer operative treatment to any patients older than sixty. However, in the present time, according to the German Pelvic Registry, over half the patients aged sixty or over, sustaining acetabular fractures underwent operative fixation. We find that the increasing age of the population raises particular challenges for the operating surgeon. Postoperative rehabilitation should be focused on early mobilisation. More research needs to be focussed on standardised treatment protocols and long-term outcomes for this cohort of patients.

Incidence of DVT and PE after surgical reconstruction for pelvic and acetabular fractures: Does routine duplex scanning affect management?

BACKGROUND: Prevention and detection of thromboembolism with pelvic and acetabular fractures remains controversial. The aim of this study was to evaluate a protocol using LMWH prophylaxis and duplex screening both pre-operatively (if there is a delay > 72 h to surgery) and post-operatively at day 5-7. We assessed the incidence of thromboembolism and associated risk factors. METHODS: A total of 255 consecutive patients who underwent pelvic and/or acetabular reconstruction in a major trauma and tertiary referral centre between January 2013 and December 2015 were studied. Forty-three patients were excluded due to non-adherence to protocol leaving 212 patients included in the study. RESULTS: Patients were of mean age 49 years (15-94) and mean ISS 24.5 (4-66). Pre-operative screening detected two patients with asymptomatic above-knee DVT who then underwent pre-operative IVC filter insertion. Post-operative screening detected seven patients (3%) with lower limb DVTs (3 proximal and 4 below knee). The three patients with proximal DVTs were fully anticoagulated and did not develop symptomatic PE. Six patients (2.8%) developed post-operative PE, four of which were symptomatic and confirmed by CT angiography. Seven patients (3%) died in the post-operative period due to non-VTE-related causes. The overall rate of VTE was 6%, including DVT 4% and PE 2.8%. PE was associated with administration of tranexamic acid in ED (p > 0.03) and total amount of blood transfused during admission (p > 0.001). VTE was not associated with age, injury type, ISS, delay to surgery or associated injuries. CONCLUSION: A protocol-based approach to VTE prophylaxis and screening in trauma patients with pelvic and/or acetabular reconstruction resulted in no VTE-related mortality. Pre- and post-operative screening for DVT changed the management in five patients, with none developing PE. Patients requiring more aggressive resuscitation had a higher rate of PE. The VTE rate was lower than previously reported.

International trauma care: initial European approaches during the COVID 19 pandemic.

The world was not prepared for the global of pandemic in early 2020 with the arrival of COVID 19. Europe has some of the most developed health care systems in the world and this article explains the initial response to the pandemic from an orthopaedic and trauma viewpoint from 8 nations. Italy reported the first cluster in February, which then rapidly spread around the continent, requiring a rapid reorganization of services. The reports highlight how elective surgery was universally stopped, surgical services were reconfigured, and new practices, such as the widespread use of telemedicine, may well become permanent. It also emphasizes how the pandemic has re-educated us on the importance of a consistent and central approach to deal with a global health crisis, and how medical services need to remain flexible and responsive to new ways of working.

Outcomes of Orthopaedic Trauma Services at a UK Major Trauma Centre During a National Lockdown and Pandemic: The Need for Continuing the Provision of Services.

Aim To review the trauma operating workload, theatre time and outcomes at a time of national lockdown at the beginning of the coronavirus disease 2019 (COVID-19) pandemic, comparing it with a year prior. Methods A retrospective case-control study was performed in a single Level 1 Major Trauma Centre (MTC) in the UK. Inclusion criteria were all patients undergoing operative intervention for an emergency or urgent trauma admission within our Trauma and Orthopaedics department. Data collected included anatomical area of injury, cause of injury, operative procedure, type of anaesthesia, total theatre time, complications, and mortality at 30 days. Results A total of 159 operations were performed on 142 patients in April 2019, and 110 operations on 106 patients in April 2020 (time of national lockdown). There was a 30% decrease due to reduced numbers of road traffic accidents and sport-related injuries. The number of hip fractures and those injuring themselves from less than 2m height remained the same. Operative total theatre time increased by a mean of 14 minutes, and complications and mortality were not significantly changed. The incidence of COVID in the patients tested was 8.5%, which matched the population incidence at the time.  Conclusions Orthopaedic trauma services need to be provided during a national lockdown. There was no decrease in the volume of patients sustaining falls, which includes hip fractures. Mean operating time only increases by 14 minutes with the wearing of PPE. This should be part of future planning of any pandemics or national lockdowns.

Bilateral acetabular fractures: Mechanism, fracture patterns and associated injuries.

INTRODUCTION: Acetabular fractures are uncommon and their management is often reserved for specialist pelvic and acetabular surgeons. Bilateral acetabular fractures are a particularly rare subgroup. We report the incidence, fracture pattern, mechanism of injury and outcome of patients presenting to a tertiary trauma centre with traumatic bilateral acetabular fractures. METHOD: Bilateral acetabular fractures were identified from a prospective database of acetabular fractures presenting to one institution over a six-year period. Patient notes and imaging studies were reviewed to identify demographics, mechanism of injury, Injury Severity Score, fracture pattern and management. Timing of operative management was explored. Patient outcomes were collected in the form of radiographs and Oxford Hip Scores at a minimum of one-year post injury. RESULTS: Eight patients with bilateral acetabular fracture were identified from a database which contained records of 519 patients with acetabular fractures (incidence of 1.5% amongst patients with acetabular fractures). Motor vehicle accidents were the most common mechanism. Four acetabular fracture patterns were observed within the cohort. Radiographic union occurred in all cases and Oxford Hip Scores are suggestive of moderate to well functioning hip joints. Fractures were treated as single or staged procedures. CONCLUSION: Bilateral acetabular fractures are very rare due to the unique degree and pattern of force required to fracture both acetabula. They are associated with 4 main fracture patterns and present with Injury Severity Scores that averaged 25 (severe). They are typically observed in young males with road traffic collision being the most common mechanism of injury.
