Out of joint: The story of the ASR
Metal on metal
- Total hip replacement surgery—The femoral head is removed and replaced with a prosthetic ball made of metal or ceramic, and the acetabulum is replaced with a prosthetic cup. The cup consists of one or two components made of metal, ceramic, or plastic. A stem is also placed in the femur to support the femoral head
- Hip resurfacing surgery—The femoral head is trimmed and capped with a metal covering. Any damaged bone and cartilage within the acetabulum are removed and replaced with a metal cup
