1 Impaction Bone-Grafting before Insertion of a Femoral Stem with Cement in Revision Total Hip Arthroplasty. A Minimum Two-Year Follow-up Study* by JOHN B. MEDING, MERRILL A. RITTER, E.

2 Fig. 1-A: Initial postoperative radiograph of a fifty-seven-year-old man who had impaction bone-grafting before insertion of the femoral stem with cement. Fig. 1-A: Initial postoperative radiograph of a fifty-seven-year-old man who had impaction bone-grafting before insertion of the femoral stem with cement. Cerclage wires were placed prophylactically before impaction. JOHN B. MEDING et al. J Bone Joint Surg Am 1997;79: ©1997 by The Journal of Bone and Joint Surgery, Inc.

Fig. 3-A Radiograph of a seventy-six-year-old woman, made twenty-one years after a left total hip replacement in which the stem was inserted with cement. There is severe polyethylene wear and associated massive osteolysis of both the femur and the acetabulum, with medial cortical erosion of the femur. JOHN B. MEDING et al.
