Osteonecrosis of the knee encompasses three conditions; spontaneous osteonecrosis of the knee, secondary osteonecrosis (ON) and post-arthroscopic ON. Early stage lesions can be managed by non-operative measures that include protected weight-bearing and analgesia. The aim of this study was to report the experience of the authors in managing early stages of knee ON by analysing the functional outcome and need for surgical intervention. All patients treated for osteonecrosis of the knee between 1st August 2001 and 1st April 2014 were prospectively collected. Treatment consisted of touch-down weight bearing for four to six weeks. The cases were retrospectively reviewed. MR imaging was evaluated for the stage of disease according to Koshino's Classification system, the condyles involved and the time taken for resolution. Tegner Activity Scale, VAS pain, Lysholm, WOMAC and IKDC scores were recorded at presentation and final follow up.Introduction
Methods
The highest incidence of recurrent shoulder instability is in young patients, surgical repair can reduce recurrent instability and improve shoulder function. This has led to an increasing rate of stabilisation and use of MRI to identify associated injuries in first time dislocations. MRA has the benefit of distending the joint and is becoming increasingly used. The aim of this study is to establish the sensitivity and specificity of MRA in the investigation of patients with traumatic anterior shoulder dislocations. A retrospective analysis of patients undergoing both magnetic resonance arthrography and arthroscopy after a traumatic anterior shoulder dislocation between January 2011 and 2014. Images were interpreted by eight musculoskeletal radiologists and arthroscopic findings were obtained from surgical notes and used as a reference. The sensitivity, specificity and positive predictive value for the different injuries were calculated.Introduction
Methods
The stability of the elbow joint following an acute elbow dislocation is dependent on associated injuries. The ability to identify these concomitant injuries correctly directs management and improves the chances of a successful outcome. Interpretation of plain radiographs in the presence of either a dislocation or post-reduction films with plaster in-situ is difficult. This study aimed to assess the ability of orthopaedic registrars to accurately identify associated bony injuries on initial plain radiographs using CT as the gold standard for comparison. Patients over the age of 16 years undergoing an elbow CT scan within one week of a documented elbow dislocation between 1st June 2010 and 1st June 2014 were included in the study. Three orthopaedic registrars independently reviewed both the initial dislocation and immediate post reduction plain radiographs to identify any associated bony injuries. This radiograph review was repeated by each registrar after two weeks. The incidence of associated injuries as well as the inter- and intra-observer variability was calculated.Introduction

Patients suffering a distal femoral fracture are at a high risk of morbidity and mortality. Currently this cohort is not afforded the same resources as those with hip fractures. This study aims to compare their mortality rates and assess whether surgical intervention improves either outcome or mortality following distal femoral fractures. Patients over sixty-five admitted with a distal femoral fracture between June 2007 and 2012 were retrospectively identified. Patients mobility was categorised as unaided, walking aid, zimmer frame, or immobile. The 30-day, six-month, and one-year mortality rates were recorded for this group as well as for hip fractures during the same period.Background

Despite arthroscopy being the gold standard for long head of biceps pathology, the literature is seemingly lacking in any critical appraisal or validation to support its use. The aim of this study was to evaluate its appropriateness as a benchmark for diagnosis. The objectives were to evaluate whether the length of the tendon examined at arthroscopy allows visualisation of areas of predilection of pathology and also to determine the rates of missed diagnoses when compared to an open approach. A systematic review of cadaveric and clinical studies was performed. The search strategy was applied to Medline, PubMed and Google Scholar databases. All relevant articles were included. Critical appraisal of clinical studies was performed using a validated quality assessment scale.Background

Distal radius fractures are common injuries but no clear consensus regarding optimal management of unstable fractures exists. Open reduction and internal fixation with volar plates is an increasingly popular but the associated complication rate can be 10%. Intramedullary nails are an alternative offering the potential advantages of reduced risk of tendon injury and intra-articular screw penetration. This article systematically reviews the published literature evaluating the biomechanics, outcomes and complications of intramedullary nails in the management of distal radius fractures. A systematic review of Medline and EMBASE databases was performed for studies reporting the biomechanics, functional outcome or complications following intramedullary nailing of distal radius fractures. Critical appraisal was performed with respect to validated quality assessment scales.Background
