Total Hip Replacement Surgery
Why is total hip replacement surgery done?
Total hip replacement surgery is a procedure done to replace all or part of the hip joint with an artificial hip joint or prostheses in order to restore movement. The prosthesis consists of
- A metal shell with an inner plastic lining that replaces the hip socket (acetabulum)
- A metal ball that will replace the fractured femoral (thigh bone) head
- A metal stem that is attached to the shaft of the bone to add stability to the prosthesis
How is a total hip replacement surgery done?
- An incision is made along the affected hip joint and the muscles and tendons are separated in order to cut and remove the femoral head and cup.
- The cartilage is removed from the hip socket where the metal shell is placed while the metal stem is inserted in the aptly shaped and hollowed femur.
- Both are fixed in place by either screwing or cementing them.
- Finally the metal ball is attached to the metal stem and the muscles and tendons are replaced against the bone after which the incision is closed.
