The use of a cementless femoral component for the management of bone loss in revision hip arthroplasty.
Thirty revision total hip arthroplasties were performed using the Wagner long uncemented femoral stem. Pre-operative indication included severe proximal femoral bone loss (and in no case was the proximal femur able to support a standard-length uncemented stem). For 15 (50%) patients the procedure was a first revision whereas the other 15 (50%) patients had already undergone one or more previous revisions. The average follow-up was 36.5 months. In all cases regeneration of the proximal femoral bone stock occurred without bone graft. Subsidence of the stem was noted in 6 (20%) patients, but was asymptomatic and did not require re-operation.
