Proximal femoral bone loss after total hip arthroplasty.

Abstract

The cause of bone loss from the proximal femur after total hip arthroplasty is multifactorial and may progress to a degree at which loss of support for the femoral component occurs. The most durable means of reconstructing the deficient proximal femur involves bone grafting techniques designed to restore mechanical integrity. Because there is seldom an adequate quantity of autogenous bone available, allograft bone is frequently used. The indications and limitations of this procedure are described as are other treatment options.
