The shoulder hemiarthroplasty is most often performed for one of three reasons. The first is an arthritic shoulder where the socket is not in bad condition, but the ball needs to be replaced. The second is in rotator cuff tear arthropathy, where a total should replacement would likely fail over time.
The shoulder is a joint with three main bones: the upper arm bone (humerus), the collarbone (clavicle), and the shoulder blade (scapula). The bones are held together by muscles, tendons, and ligaments. The rotator cuff keeps the upper arm bone in the shoulder socket and lets you raise and twist your arm.otator cuff disorders include: 1  Inflammation of the tendons (tendinitis) or of a bursa (bursitis). 2  Impingement, in which a tendon is squeezed and rubs against bone. 3  Calcium buildup in the tendons, which causes a painful condition called calcific tendinitis. 4  Partial or complete tears of the rotator cuff tendons.
