In a total hip replacement surgery, the painful parts of the damaged hip are replaced with artificial hip parts called a 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.
The procedure is performed through an incision over the side of the hip. The ball-end of the thighbone (femur) is cut and replaced with the new metal ball and stem component. It may be stabilized with or without cement. The damaged surface of the socket is smoothed in preparation for the insertion of the new socket. The ball and socket are then joined.
The implant is affixed in the body by
• Bone Cement
A special type of bone acrylic cement may be used to secure some or all of the implant components to the bone. If used, the bone cement takes about 15 minute to set.
• Press-
In other cases, the implants may be "press-fit" into the bone. Press-fit components may have a special porous coating that allows tissue to grow up to it for fixation.
• Combination
In some cases, your surgeon may choose a combination of cement and press-fit attachment, depending upon the implant components and condition of the pelvic and thigh bone.The decision as to whether to use a cemented or press-fit component depends upon many factors, including surgeon philosophy and the
The longevity of the prosthetic varies with every patient depending upon physical condition, activity level, weight as well as the accuracy of implant placement during surgery.
Total hip replacement has become a common and predictable surgery, with very high success rates.
