title: Surgical treatment of osteonecrosis of the hip.
abstract: Various surgical procedures are used in patients with osteonecrosis of the hip. Patients with precollapse of the femoral head are generally treated with head-preserving procedures (core decompression, various bone grafting techniques, and osteotomies), whereas those with collapse of the femoral head and/or arthritis may require arthroplasty. The arthroplasty options available include limited femoral resurfacing arthroplasty, metal-on-metal resurfacing arthroplasty, or total hip replacement. The indications, techniques, and early outcomes of some of these procedures for treatment of osteonecrosis of the hip merit discussion.
