Prostheses, Joint, Shoulder

Definition : Implantable prostheses designed to totally or partially replace the shoulder joint. Partial shoulder prostheses typically consist either of a humeral component (consisting of a long stem that is anchored in the hollow center of the humerus at one end and a cup that is attached at the other end forming the ball of the articulation) or a glenoid component (consisting of a metal tray with a short stem that is anchored directly to the scapula and a plastic cup that replaces the glenoid cavity of the shoulder blade at the articulation point). The prosthesis components can be anchored in the bone using orthopedic cement (e.g., epoxy) or by integration using mesh. Total shoulder joint prostheses typically include both humeral and glenoid components. Shoulder joint prostheses are used in patients who suffer from osteoarthritis or rheumatoid arthritis or, less frequently, after trauma (e.g., fracture).
