Pelvic Allograft

A 23-year-old man with a large chondrosarcoma of the right bony pelvis was successfully treated by limb-saving internal hemipelvectomy and anatomic reconstruction of the pelvis by a pelvic os-teoarticular allograft including the acetabulum. Optimum anatomic fit was achieved at the hip joint as well as at the iliac and pubic host-graft junctions, which were fixed with plates and screws. This reconstruction restored stability, leg length, hip motion, and cosmesis. Five and one-half years postoperatively, the patient remained asymptomatic with good functional and roentgen-ographic results.
