Pelvic Reconstruction With a Free Vascularized Distal Femur for Revision Total Hip Arthroplasty

Abstract

The reconstruction of massive structural acetabular defects after revision arthroplasty presents a unique challenge to the orthopedic surgeon. This report describes such a salvage procedure where an autologous vascularized distal femur was used to reconstruct acetabular bone stock with subsequent implantation of a total femoral endoprosthetic replacement that uses a constrained cup and a hinged total knee system. At 2 years of follow-up, there is a good functional result with full incorporation of the graft.
