Radiograph of a thirty-year-old man with a superomedial contained defect, made ten years after a hemiarthroplasty for the treatment of avascular necrosis of the femoral head.



Radiograph made 11.5 years after revision surgery with use of morselized allograft bone and an uncemented cup.



Radiograph of a sixty-year-old woman with a contained defect, made several years after a hemiarthroplasty for the treatment of a fracture of the right hip.



Radiograph made five years after revision surgery with a roof reinforcement ring and morselized allograft bone.



Drawing showing an uncontained defect involving <50% of the acetabulum.



The structural allograft (shelf or minor column), which is fixed by cancellous screws, supports <50% of the cup.



Radiograph of a thirty-two-year-old woman who had a bipolar arthroplasty because of hip dysplasia and osteoarthritis, showing the poor coverage of the bipolar cup.



Radiograph made fourteen years after revision surgery with a minor column (shelf) allograft and an uncemented cup.



Drawing showing an uncontained defect involving >50% of the acetabulum and pelvic discontinuity.



The hip is reconstructed with a structural allograft that is fixed with two cancellous screws and protected by a reconstruction ring that is fixed to the ilium and the ischium.



Radiograph of the pelvis of a seventy-seven-year-old man with a loose cemented cup and massive osteolysis of the right acetabulum involving >50% of the acetabulum and pelvic

discontinuity.



Radiograph made five years after reconstruction with a major column allograft protected by a reconstruction ring that extended from host ilium to host ischium.

A proximal femoral allograft-implant composite is inserted into the host canal without cement.



Radiograph of a sixty-six-year-old woman with a periprosthetic fracture and loss of proximal femoral bone stock.



The femur was reconstructed with a proximal femoral allograft.
