Abstract
This case report describes the successful use of a novel "conservative hip replacement" in conditions precluding the use of a standard total hip arthroplasty in a 70-year-old man. The femoral canal was occluded because of previous surgery for a bone tumor in the subtrochanteric region. The patient continues to do well at 4 years with minimal discomfort. At this interval, the Oxford Hip Score was 35. This conservative hip replacement has been developed to preserve bone stock and produce more physiologic loading of the proximal femur. Its design has been produced, using plain radiographs and computed tomography, to maximize "fit and fill" of the femur. The neck supports standard modular heads, allowing the use of any bearing surface. The prosthesis has been rigorously laboratory tested.
