Abstract
From 1992 to 1995, 71 total hip arthroplasties with extensive acetabular bone loss underwent revision using bulk allografts and Burch-Schneider anti-protrusion cages. Twelve patients died of unrelated causes and 3 were lost to follow-up. Fifty-six hips were available for clinical and radiographic follow-up examination at an average of 11.7 years after surgery. The average final Harris hip score was 75. X-ray signs of incorporation of massive bone graft were observed in 49 hips. Two cases developed deep infection that required resection arthroplasty. Aseptic loosening of the acetabular cage occurred in 5 patients, and 2 of them underwent re-revision. With a total survival rate of 87.5%, anti-protrusion cages and structural allografts compare favorably with other techniques in the long-term reconstructive treatment of extensive loss of acetabular bone stock.
