Cup arthroplasty, surface replacement arthroplasty, and femoral head resurfacing for osteonecrosis.
Traditional cup arthroplasty and resurfacing arthroplasty of the femoral head and acetabulum have been proposed as bone-conserving procedures for avascular necrosis of the hip.  Resurfacing of only the femoral head is not a definitive procedure but is an alternative to cup arthroplasty and resurfacing arthroplasty of the femoral head and acetabulum; hemiarthroplasty is recommended for the young patient with intact acetabular cartilage. Indications, technique, and clinical results are presented.
