Partial Shoulder Replacement

A surgical procedure performed to replace the joint surface of the ball (head of humerus) of the shoulder. An incision is made on the front of the shoulder and the shoulder joint is exposed. The worn joint surface of the humerus is removed. A metal stem is placed in the humerus bone and secured. An appropriately sized ball component is then attached to the stem. Once the components are secured the shoulder is checked to ensure appropriate range of motion and stability of the implants.
