How a reverse total shoulder arthroplasty works
A reverse shoulder replacement changes the way your shoulder works. It transfers more of the load to your deltoid muscles and less to the rotator cuff muscles. The ball and socket in your shoulder will be replaced and reversed. The ball portion of your shoulder is replaced with a plastic cup that is attached to the top of a metal stem that is placed in the humerus (upper arm) bone.
The best results are seen in people who have some functioning rotator cuff tendons and muscles.
