Prosthetic hip. Close-up of the components of a prosthetic (artificial) hip joint,including the metal ball and shaft,and a plastic socket. Prosthetic hip joints are used to replace diseased hip joints that have become stiff and painful as a result of arthritis. In a hip replacement,the "ball" at the end of the thigh bone is removed and the "socket" in the pelvis is enlarged. The arti- ficial components are then cemented in their place,the shaft fitting into a specially made hollow inside the thigh bone. Hip replacement is a very successful operation that has transformed many lives,but the long-term outlook is uncertain as the artificial joint may loosen with time | |
