Shoulder joint components may be held in place with cement. Or they may be made with material that allows new bone to grow into the joint component over time to hold it in place without cement. The top end of your upper arm bone is shaped like a ball.
Muscles and ligaments hold this ball against a cup-shaped part of the shoulder bone.
General anesthesia is often appropriate for joint replacement surgeries.
Your surgeon may recommend that you take antibiotics before and after the surgery to reduce the risk of infection.
If you need any major dental work, it may be recommend that you have it done before the surgery.
Infections can spread from other parts of the body, such as the mouth, to the artificial joint and cause a serious problem.
