Research summary
In patients with severe hip arthritis where surgery is considered a suitable option, an alternative to a total hip replacement (THR) procedure is hip resurfacing arthroplasty (HRA). A THR requires that the femoral head (top of the thigh bone) is removed and replaced with a prosthetic device, and also that a device is inserted into the acetabulum (socket) of the hip. A HRA preserves the patient's bone by leaving the femoral head in place, and instead placing with a metal cap over the top. A device is then inserted into the acetabulum as with a THR. Many implant manufacturers have withdrawn their resurfacing products altogether or restricted them to only men with large (>48mm) diameter bearings meaning that, for those with smaller hips sizes, the options for bone preserving surgery are limited. One option is for bespoke devices to be custom made for the patient, something that is utilised already within our Trust. However, as these devices are currently custom-made to order as required for patient care, we aim to collate data in a standardised way to allow an observation of the improvement of functional outcomes of using these devices, and to identify any correlations that may be indicative of future research into these implants.
