Management of acetabular bone stock deficiency

Acetabular bone stock deficiency in primary and revision total hip arthroplasties can usually be effectively managed by combining the use of appropriately designed implants and structural or nonstructural bone grafts or bone graft substitutes. An appreciation of the deformity before Surgery will allow for proper planning and execution of a plan at the time Of surgery. The presence of segmental defects or pelvic instability is particularly important to assess preoperatively. Adherence to basic principles of bone grafting and implant fixation allows surgeons to reliably manage these potentially difficult problems.
