Total hip arthroplasty with a special segmental replacement of the
proximal end of the femur which varied in length from eighty to 150
millimeters was performed in twenty-one patients who had severe
non-neoplastic conditions of the proximal part of the femur that
necessitated salvage. Ten patients had previously failed arthroplasties
associated with loss of bone structure; seven had non-union of a proximal
femoral fracture or osteotomy associated with severe hip disease; there had
a failed resection arthroplasty; and one had an arthrodesis and
incapacitating low-back pain. Clinical and roentgenographic data during
follow-up of twenty-five to ninety-two months showed that only one patient
had loosening of the acetabular component. In twenty of the twenty-one
patients, total hip arthroplasty with proximal femoral replacement was
effective in restoring the integrity of the bone and restoring function of
the hip.
