Abstract. Introduction. Skeletal muscle wasting is an important clinical issue following acute traumatic injury, and can delay recovery and cause permanent functional disability particularly in the elderly. However, the fundamental mechanisms involved in trauma-induced muscle wasting remain poorly defined and therapeutic interventions are limited. Objectives. To characterise local and systemic mediators of skeletal muscle wasting in elderly patients following acute
Introduction. Femoral head osteonecrosis (FHO) is a condition in which the inadequate blood supply disrupts osteogenic-angiogenic coupling that results in diminishment of femoral perfusion and ends up with FHO. The insufficient knowledge on molecular background and progression pattern of FHO and the restrictions in obtaining human samples bring out the need for a small animal
Since the emergence of the COVID-19 pandemic, the NHS has been under unprecedentedpressure. Elective surgery had ceased, and trauma surgery has decreased dramatically. Surgical training is multi-faceted and requires a specialist trainee to have a timetable which includes regular elective non-emergency operating,
Introduction. We aimed to study the rates of both surgical and medical complications associated with femoral diaphysis fracture fixation with intramedullary nailing including all fracture mechanisms. Additionally, we investigated whether the

Abstract. Objectives. Our objective was to determine the incidence of post-operative COVID-19 infection within the first two weeks following treatment at the COVID-free site. During the COVID-19 pandemic our hospital saw one of the highest rates of COVID-19 infection in the United Kingdom. As a result, our
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
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
Introduction. With advances in artificial intelligence, the use of computer-aided detection and diagnosis in clinical imaging is gaining traction. Typically, very large datasets are required to train machine-learning models, potentially limiting use of this technology when only small datasets are available. This study investigated whether pretraining of fracture detection models on large, existing datasets could improve the performance of the model when locating and classifying wrist fractures in a small X-ray image dataset. This concept is termed “transfer learning”. Method. Firstly, three detection models, namely, the faster region-based convolutional neural network (faster R-CNN), you only look once version eight (YOLOv8), and RetinaNet, were pretrained using the large, freely available dataset, common objects in context (COCO) (330000 images). Secondly, these models were pretrained using an open-source wrist X-ray dataset called “Graz Paediatric Wrist Digital X-rays” (GRAZPEDWRI-DX) on a (1) fracture detection dataset (20327 images) and (2) fracture location and classification dataset (14390 images). An orthopaedic surgeon classified the small available dataset of 776 distal radius X-rays (Arbeidsgmeischaft für Osteosynthesefragen Foundation /
A hot swollen joint is a commonly encountered condition in clinical practice. With a broad range of differentials, septic arthritis (SA) is perhaps one of the most concerning. Treated by culture-specific antibiotics and arthroscopic lavage, some patients require multiple washouts. We aimed to determine:. (1) What are the risk factors for development of SA?. (2) What are the risk factors for repeat washout in SA patients?. (3) What are the important clinical differences between a periprosthetic joint infection (PJI) and SA cohort?. All patients presenting to the emergency department, orthopaedic, and rheumatology clinics between January 2020 to January 2021 with a hot, swollen joint were retrospectively evaluated. Patients with previous
Distal radius fractures (DRF) are very common injuries. National recommendations (British Orthopaedic Association, National Institute for Health and Care Excellence (NICE)) exist in the UK to guide the management of these injuries. These guidelines provide recommendations about several aspects of care including which type of injuries to treat non-operatively and surgically, timing of surgery and routine follow-up. In particular, current recommendations include considering immobilizing patients for 4 weeks in plaster for those managed conservatively, and operating on fractures within 72 hours for intra-articular injuries and 7 days for extra-articular fractures. With increased demands for services and an ageing population, prompt surgery for those presenting with distal radius fractures is not always possible. A key factor is the need for prompt surgery for hip fracture patients. This study is an audit of the current standard of care at a busy level 2
Introduction and Objective. Hemorrhagic shock and fractures are the most common injuries within multiple injured patients, inducing systemic and local inflammation in NF-kappaB-dependent manner. Alcohol intoxication, showing a high incidence with severe injuries, has immunomodulatory properties and implicates NF-kappaB downregulation. However, the mechanism is largely unknown. A20 deubiquitinase is a critical negative regulator of NF-kappaB activity and inflammation. Here, we investigate the role of A20 as a modifier of NF-kappaB-driven inflammation and remote lung injury in severely injured and alcohol-intoxicated mice. Materials and Methods. Mice were randomly divided into four groups. Either sodium chloride or ethanol (35%, EtOH) was administrated by intragastral gavage one hour before
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

Venous Thromboembolism (VTE) prophylaxis is an essential part of orthopaedic surgeries in preventing life-threatening thromboembolic events such as Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE). Orthopaedic surgery has the highest incidence rate of thromboembolic events as compared to any other surgical specialities, making it an essential component in managing any orthopaedic case.
