Birmingham Hip Resurfacing (BHR)
The Birmingham Hip Resurfacing (BHR) is a metal-on-metal prosthesis used in hip resurfacing procedure. Hip Resurfacing is a bone conserving procedure where the acetabulum (hip socket) is replaced and femoral head is resurfaced. Hip resurfacing is indicated in all the individuals with arthritis where conservative treatment was a failure. Advantage of hip resurfacing procedure is that the little bone is removed from the femoral head and this spares the femoral canal.
The conventional method of total hip replacement offers poor long-term outcomes for young and active patients leading to further complications such as revision surgery and associated problems. In hip resurfacing, the articular surfaces of the femur and acetabulum are replaced. The procedure is bone conserving as most of the head of the femur is retained. Instead of removing the head completely as with a total hip replacement, it is shaped to accept a low-wear metal sphere. This sphere matches the patient's own anatomy that confers low risk of dislocation, a broad range of movement and excellent stability. A comprehensive range of sizes is offered to address the needs of almost all patients, and those with acetabular deficiencies. The BHR offers a bone conserving, less invasive alternative to total hip replacement, with the potential for higher levels of normal activity. The BHR device is designed so as to suit cemented fixation or cement-less press-fit fixation. The resurfacing femoral head and acetabular cups are available in various sizes so as to suit everyone's needs. The BHR system has allowed many young and active patients, athletes, and sports personalities with arthritic hip to perform their normal activities with no or minimal pain. It can be used in all individuals aged less than 60 years and also in individuals aged more than 60 years with bone quality strong enough to support the implant.
