Introduction.
High energy pelvic injury poses a challenging setting for the treating surgeon. Often multiple injuries are associated, which makes the measurement of short- and long-term functional outcomes a difficult task. The purpose of this study was to determine the incidence of pelvic dysfunction and late impacts of high energy pelvic ring fractures on pelvic floor function in women, with respect to urinary, sexual and musculoskeletal function. This was compared to a similar cohort of women with lower limb fractures without pelvis involvement. The data in our study was prospectively gathered between 2010 and 2013 on 229 adult females who sustained injury between 1998 and 2012. Besides demographic and operative variables, the scores of three validated health assessment tools were tabulated: King's Health Questionnaire (KHQ), Female Sexual Function Index (FSFI) and the Short Musculoskeletal Functional Assessment (SMFA). A multivariate regression analysis was done to compare groups. The incidence of sexual dysfunction was 80.8% in the pelvis and 59.4% in the lower extremity group. A Wilcoxon rank sum test showed a significant difference in KHQ-score (p<0.01) with the pelvis group being worse. When adjusting for age, follow-up and Injury Severity Score this difference was not significant (p=0.28), as was for FSFI and SMFA score. The mean FSFI scores of both groups met the criteria for female sexual dysfunction (<26). Patients with a Tile C fracture have better FSFI scores (16.98) compared to Tile B fractures (10.12; p=0.02). Logistic regression predicting FSFI larger than 26.5 showed that older age and
Major orthopaedic fractures are an independent risk factor for the development of venous thromboembolism (VTE), which are significant causes of preventable morbidity and mortality in trauma patients. Despite thromboprophylaxis, patients who sustain a pelvic or acetabular fracture (PA) continue to have high rates of VTE (12% incidence). Thrombelastography (TEG) is a whole-blood, point-of-care test which provides an overview of the clotting process. Maximal amplitude (MA), from TEG analysis, is the measure of clot strength and values ≥65mm have been used to quantify hypercoagulability and increased VTE risk. Therefore, the primary aim was to use serial TEG analysis to quantify the duration of hypercoagulability, following surgically treated PA fractures. This is a single centre, prospective cohort study of adult patients 18 years or older with surgically treated PA fractures. Consecutive patients were enrolled from a Level I trauma centre and blood draws were taken over a 3-month follow-up period for serial TEG analysis. Hypercoagulability was defined as MA ≥65mm. Exclusion criteria: bleeding disorders, active malignancy, current therapeutic anticoagulation, burns (>20% of body surface) and currently, or expecting to become pregnant within study timeframe. Serial TEG analysis was performed using a TEG6s hemostasis analyzer (Haemonetics Corp.) upon admission, pre-operatively, on post-operative day (POD) 1, 3, 5, 7 (or until discharged from hospital, whichever comes sooner), then in follow-up at 2-, 4-, 6-weeks and 3-months post-operatively. Patients received standardized thromboprophylaxis with low molecular weight heparin for 28 days post-operatively. VTE was defined as symptomatic DVT or PE, or asymptomatic proximal DVT, and all participants underwent a screening post-operative lower extremity Doppler ultrasound on POD3. Descriptive statistics were used to determine the association between VTE events and MA values. For the primary outcome measure, the difference between the MA threshold value (≥65mm) and serial MA measures, were compared using one-sided t-tests (α=0.05). Twenty-eight patients (eight females, 29%) with a mean age of 48±18 years were included. Acetabular fractures were sustained by 13 patients (46%),

This study defines the patterns of perineal injury due to blast currently seen on operations. It refines our team-based surgical strategies of surgical resuscitation provides an evidence base for a perineal debridement - colonic diversion didactic on the Military Operational Surgical Training (MOST) course. The Joint Theatre Trauma Registry (JTTR) held at RCDM was examined from 1 January 2003 to 31 December 2010. Data abstracted included patient demographics, mechanism of injury, injury severity score (ISS), treatment, management, length of stay (LOS) and outcomes. Of 4807 military trauma patients, 118 (2.5%) had a recorded perineal injury, 56 died (48% all IED).
Objective. The optimal positioning of the acetabular component is a relevant prognostic factor in total hip arthroplasty (THA). Because of substantial errors of manual technique in cup placement even with experienced surgeon, computer aided navigation system has been developed in recent years. However, existence of the hardware around acetabulum likely deteriorates the accuracy of the navigation system, namely in revision THA case and postoperative status of

Pelvic ring fractures usually result from significant trauma, frequently requiring operative stabilisation. The use of an anterior internal fixator (INFIX) is a new technique. This temporary construct is quick and easy to apply using pre-existing spinal implants. No reports of functional outcomes or compartive studies with existing surgical techniques exist in indexed literature. We present a prospective comparative case matched series of 21 patients treated with pelvic INFIX. 1:1 matching was achieved to a cohort of patients treated with open reduction and internal fixation (ORIF) based on fracture pattern. All patients with rotationally and/or vertically unstable pelvic ring fractures treated within our level 1 trauma centre were considered for inclusion. Patients were prospectively followed up with health outcome measures (SF-36, EQ-5D) and joint specific outcome scores (Oxford and Harris hip scores). Results. No statistically significant differences in age (mean 42v38 p=0.3143), length of stay, or operative time were seen. The ISS was significantly higher in the INFIX group (32v22 p=0.0019). Mean INFIX removal was at 14 weeks. Baseline responses were obtained on admission where feasible. Although there was no significant difference between the treatment groups, the ORIF group showed a significantly greater deterioration from the baseline than the INFIX group, suggesting INFIX better maintains pre-injury function. 29% of patients experienced LCNT palsy whilst the INFIX was in situ. 6 patients in the INFIX group experienced some form of metal work failure (3 required surgical removal), compared with 7 ORIF patients (4 required removal). Conclusions. Pelvic INFIX achieves bony stabilisation of unstable
To analyse and compare long-term functional outcome of combined spino-pelvic injuries to an isolated pelvis and spinal fractures, the outcome of matched 30 patients with combined pelvic and spinal fractures was compared with 32 patients with isolated
Purpose. Radiographs are the most common imaging modality used to guide orthopaedic interventions. Ultrasound (US) imaging offers potential advantages for intraoperative imaging by its portability and ability to produce real-time 2D or 3D images without radiation to either the patient or surgical team. Our objective in this study was to determine in a live emergency room setting, if a newly-developed image processing method for 3D US would allow us to accurately extract (reproduce) the surfaces of fractured bones. Method. We obtained both CT scans and US images from consenting patients admitted to our Level 1 Trauma Centre for radius or
The UK Military Trauma Registry was searched for all cases of primary bilateral lower limb amputation sustained over 6-years between March 2004 and March 2010. There were 1694 UK military patients injured or killed during this six-year study period. Forty-three of these (2.8%) were casualties with bilateral lower limb amputations. All were men injured in Afghanistan by Improvised Explosive Devices. Six casualties were in vehicles when they were injured with the remaining 37 (80%) patrolling on foot. The mean New Injury Severity Score was 48.2 (SD 13.2). Nine patients also lost an upper limb (triple amputation); no patients survived loss of all four limbs. Six patients (14%) sustained an open
Orthopaedic surgeries are complex, frequently performed procedures associated with significant haemorrhage and perioperative blood transfusion. Given refinements in surgical techniques and changes to transfusion practices, we aim to describe contemporary transfusion practices in orthopaedic surgery in order to inform perioperative planning and blood banking requirements. We performed a retrospective cohort study of adult patients who underwent orthopaedic surgery at four Canadian hospitals between 2014 and 2016. We studied all patients admitted to hospital for nonarthroscopic joint surgeries, amputations, and fracture surgeries. For each surgery and surgical subgroup, we characterized the proportion of patients who received red blood cell (RBC) transfusion, the mean/median number of RBC units transfused, and exposure to platelets and plasma.Aims
