Hip Bursectomy (Hip Bursa)
The hip, like the shoulder, is a ball-and-socket joint. This means that the top of the femur bone is round and fits into the socket portion of the pelvic bone. The hip bursa contains a fluid that lubricates joints, and the bursa may need to be drained or removed altogether. With a total hip replacement, the surgeon removes the ball from the femur and inserts a metal one. Damaged cartilage is also removed from the socket and replaced so that the new ball moves smoothly within the socket.
