Hip joint replacement

A surgical procedure performed to replace the ball-and-socket joint of the hip with a specially designed prosthesis. A prosthetic hip joint replacement is implanted after removal of the diseased bone tissue and cartilage from the natural hip joint. Conditions that may lead to the need for this procedure include degenerative osteoarthritis, rheumatoid arthritis, injury, bone tumors, and avascular necrosis of the femoral head (insufficient blood supply leading to death of bone tissue). Before surgery the extent of damage to a joint is diagnosed and evaluated by a physical examination, by X rays, and possibly by certain laboratory tests.
