There are different types hip replacements. If a hemi-arthroplasty is performed, either the femoral head or the hip socket (acetabulum) will be replaced with a prosthetic device. In a total hip replacement, both the femoral head and the hip socket is replaced by the prosthetic device.
In a total hip replacement surgery, the painful parts of the damaged hip are replaced with artificial hip parts called prosthesis, a device that substitutes or supplements a joint. The prosthesis consists of steel components: a socket, ball, and stem. The outer shell of the socket is usually made of metal and the inner shell consists of plastic, or the entire socket may be plastic. When the metal ball is joined with the socket, the new hip can allow for smooth, nearly frictionless movement.
Hip replacement is currently the most common orthopaedic operation.
