Subcapital prosthesis fracture in total hip arthroplasty: case report.

There have recently been multiple reports of late complications of femoral stem fractures occurring after total hip replacement arthroplasty of the hip. The case presented is the first case reported in the English literature of a subcapital prosthesis fracture involving a Charnley-Mueller design femoral component. Revision surgery was carried out with satisfactory replacement of the failed component.
