Revision Hip Replacement
The part of the thigh bone and the ball is replaced in a complete hip replacement and a new, smaller artificial ball is inserted in the remainder of the thigh bone. The surface of the existing pelvis socket is formed to accept the new socket component to articulate the new ball component.
Many artificial joint components with acrylic cement are bonded into the bone. However, implantation without cement is becoming more frequent for one part, or both parts, especially in younger patients. If cement is not used, the implant surfaces will be roughened or treated especially to facilitate bone to grow on them.
