Pathological Fracture of the Femur Following Chronic Osteomyelitis: A Case Report of This Rare Presentation in Adults.

Chronic osteomyelitis is a common presentation in orthopaedics, particularly in the context of deep abscesses. Fractures related to osteomyelitis can be seen in children but are rare in adults. We present the rare case of a pathological fracture related to osteomyelitis in a 53-year-old warehouse worker who was previously fit and well. He presented with a right-sided thigh abscess and after initial surgical management, further imaging detailed osteomyelitis that was treated with suppressive antimicrobial therapy. Seven months after discharge, the patient presented to our emergency department with a right-sided proximal fracture of the femur. Retrospectively, we were able to localise the fracture site to the site of the previous cloaca from the osteomyelitis. We discuss whether prophylactic fixation is required for patients with extensive cloaca following a chronic fracture.

Assessing the attitude of surgical trainees towards virtual reality simulation: A national cross-sectional questionnaire study.

BACKGROUND: We performed a cross sectional study to determine the attitudes of surgical trainees and medical students towards virtual reality (VR) simulation in surgical training. A survey was devised through an iterative process before distribution to surgical trainees, foundation year doctors and medical students through online platforms. METHODS: The survey was disseminated within the United Kingdom through social media and email correspondence, in co-operation with national surgical organisations. 91 trainees responded from a variety of clinical specialities. RESULTS: VR technology in surgical training was viewed positively, with 91.3% of trainees agreeing that VR should be both an adjunct in surgical training as well as a competency-based assessment tool. Barriers to access were present, with access notably more challenging for senior surgeons. CONCLUSION: Virtual reality surgical simulation in surgical training is beginning to emerge as a genuine high-fidelity, low-risk solution to the lack of surgical case volume trainees are currently experiencing.

The role of hydroxyapatite coating in joint replacement surgery - Key considerations.

The use of a porous hydroxyapatite (HA) coating has definitively increased the durability and biocompatibility of joint replacement prostheses (JRP) since its introduction. This article will contextualise the properties of porous HA and relate these characteristics to its clinical function. Novel strategies to encourage osseointegration will also be explored, alongside their clinical relevance. All major literature databases were scrutinised for literature relevant to the scope of our review. The role of Hydroxyapatite was evaluated, alongside further strategies to augment bone ingrowth. HA coatings remain the most optimal coating for widespread clinical use. Advantages are conferred due to the method of application, the tribology and the biocompatibility of the material. Further strategies are available to augment bone ingrowth, pertaining to biological modifications and implantation of external factors. An evaluation of the literature has described the relative long term performance of the HA coated JRPs both in isolation and when compared with cemented prosthesis. Metanalyses have shown HA coated JRPs to perform as well as cemented prosthesis in terms of survivability over both short and long term follow ups. Concerning strategies to augment osseointegration, consideration should be given to form and function of the coating surface, as this provides the basis for cell adherence, proliferation, and differentiation.
