Angioembolisation for arterial haemorrhage related to pelvic ring injury.

INTRODUCTION: Haemorrhage related to pelvic fractures has been associated with mortality rates of up to 50%. Angioembolisation for the management of pelvic haemorrhage was performed as early as 1972; however, there remains uncertainty over its exact use, timing and priority as a component of modern pelvic management protocols. METHODS: We retrospectively analysed cases of angioembolisation for arterial haemorrhage related to pelvic ring fractures at a level 1 trauma centre. Patient demographics were assessed as well as the time taken to reach the interventional radiology (IR) suite from the time of trauma and also arriving at the emergency room (ER). Other factors analysed included the volume of blood products consumed and fracture pattern. RESULTS: Fifty-four patients received pelvic angiography for pelvic ring injuries between 2006 and 2021. The average age was 45.1 (20.5) years, with the male to female ratio 2.4:1. Forty (74.1%) of these patients had embolisation to actively bleeding pelvic arterial vessels. Median time to the IR was 4.4 [IQR 3.1-8.1] hours from time of trauma and 2.5 [IQR 2.1-4.2] hours from arrival to ER. The overall mortality rate was 18.5% and the median amount of blood transfused was 4584 mL [IQR 1643.5-8026.5]. In the subset of embolised patients (n = 40), mortality rate was 10% and there was an inverse association between time from ER to IR and volume of blood product consumption (P = 0.024). CONCLUSION: Angioembolisation is a life-saving intervention in very severely injured patients and is growing in popularity as a component of modern pelvic trauma management protocols.

An update on reverse total shoulder arthroplasty: current indications, new designs, same old problems.

Reverse total shoulder arthroplasty (RTSA) was originally developed because of unsatisfactory results with anatomic shoulder arthroplasty options for the majority of degenerative shoulder conditions and fractures.After initial concerns about RTSA longevity, indications were extended to primary osteoarthritis with glenoid deficiency, massive cuff tears in younger patients, fracture, tumour and failed anatomic total shoulder replacement.Traditional RTSA by Grammont has undergone a number of iterations such as glenoid lateralization, reduced neck-shaft angle, modular, stemless components and onlay systems.The incidence of complications such as dislocation, notching and acromial fractures has also evolved.Computer navigation, 3D planning and patient-specific implantation have been in use for several years and mixed-reality guided implantation is currently being trialled.Controversies in RTSA include lateralization, stemless humeral components, subscapularis repair and treatment of acromial fractures.

Isolated Rupture of the Short Head of the Biceps at the Proximal Musculotendinous Junction: A Report of Two Cases.

CASE: Two men aged 19 and 21 years sustained wakeboarding injuries where the towrope was forced against the anterior region of the arm. Physical examination revealed bruising and tenderness over the biceps with weakness in elbow flexion. Magnetic resonance imaging demonstrated complete musculotendinous rupture of their short head of biceps. Surgical repair followed by cast immobilization led to an excellent outcome in both cases. CONCLUSIONS: This is a unique series of complete musculotendinous rupture of the short head of the biceps occurring in wakeboarding accidents, with the mechanism of injury resisted shoulder adduction and flexion.

Randomised clinical trial assessing migration of uncemented primary total hip replacement stems, with and without autologous impaction bone grafting.

PURPOSE: Uncemented stems in primary total hip replacement (THR) are concerning in the elderly due to ectatic femoral canals and cortical thinning resulting in higher incidence of fracture and subsidence in this population. To obviate this concern, the authors developed a technique using autologous impaction bone grafting to achieve a better fitting femoral stem. The aim of this randomised clinical trial was to assess the efficacy of the technique. METHODS: From 2013 to 2015, a total of 98 consecutive participants (100 primary THR procedures) were inducted into a single-institution, single-blinded, randomised clinical trial assessing, with radiostereometric analysis (RSA), the efficacy of autologous impaction bone grafting in uncemented primary THR compared with traditional uncemented primary THR technique. The primary outcome measure was femoral component migration using RSA. Secondary outcomes were post-operative proximal femoral bone density (using DEXA), hip function and quality of life using Oxford Hip Score (OHS) and Short Form-12 Health Survey (SF-12), hip pain and patient satisfaction. RESULTS: There was no difference in femoral component stability (p > 0.5) or calcar resorption between the Graft and No Graft Groups at two years. There was also no difference in OHS, SF-12, pain or satisfaction between the Graft and No Graft Groups at two years (p > 0.39). CONCLUSIONS: Autologous impaction bone grafting in uncemented primary THR has shown its short-term post-operative outcomes to be equivalent to standard uncemented technique, whilst offering a better fit in patients who are between femoral stem sizes.
