Bone grafts, bone graft extenders, substitutes and enhancers for acetabular reconstruction in revision total hip arthroplasty

[摘要] Bone loss is a major concern of revision total hip arthroplasty (THA). While on the femoral side the problem is commonly solved by passing the defect through long stems seeking distal fixation in the healthy diaphysis, on the acetabular side any bone defect might severely affect the chance of achieving an adequate component stability, and an acceptable reconstruction of the hip anatomy and of the centre of rotation. Acetabular bone deficiencies are almost always managed with bone stock-restoring techniques (namely bone grafting), although in the last decade the availability of modular porous metal augments1,2 has introduced a viable alternative, especially attractive for older patients unlikely to undergo further revisions.
