Routine Post-operative Radiographs Following Hip Hemiarthroplasty: Is It a Necessity?

Femoral neck fractures are one of the most common fractures treated by an Orthopaedic surgeon. Arthroplasty is the recommended management for intracapsular neck of femur fractures in the elderly population owing to the high risk of avascular necrosis of the femoral head following an internal fixation. Elderly patients with intracapsular fractures deemed high risk for anaesthesia (American Society of Anaesthesiology Grade more than 2) are recommended a hip hemiarthroplasty. Routine practice throughout the United Kingdom is to obtain a postoperative check radiograph for all hip hemiarthroplasty patients prior to their discharge from the hospital. This may be done for various reasons like checking the presence of any peri-prosthetic fracture, the position of the components along with the presence of any dislocation. However, it is unclear whether a radiograph is the sole identifier of such complications. Through this study, we aim to analyse whether routine recommendation of post-operative radiographs following hip hemiarthroplasty affects the clinical outcome, and whether it is effective in identifying potential complications before the patients report any signs or symptoms.
