Arthroplasty of the hip may be categorized as a total hip arthroplasty or a hemiarthroplasty. In a total hip arthroplasty, the articular surfaces of both the acetabulum and femur are replaced. This involves either replacement of the femoral head and neck (conventional total hip arthroplasty) or replacement of the surface of the femoral head (resurfacing total hip arthroplasty); both procedures also replace the acetabulum.
