Shoulder replacement - reverse surgery is similar to a standard shoulder replacement, in which the diseased head (ball) of your shoulder joint is removed. However, instead of replacing it with a new ball, a socket is created on the arm side and a ball is created on the shoulder side.
The joint is therefore “reversed” from the original structure. The ball is slipped into the socket to restore movement and create the new joint. For some patients, this reverse approach provides greater range of motion.
