Replacements – Shoulder
Shoulder Replacement
Shoulder Replacement surgery involves the removal of the diseased head (ball) of your shoulder joint, and the placement of a metal stem into your upper arm bone (humerous). A metal or ceramic ball is then placed on the stem, forming the first half of the new shoulder joint. The shoulder section is then reshaped and lined with a metal or ceramic cup creating a new socket for the ball to sit in. The socket may also receive a plastic liner to keep the new joint moving smoothly. The ball is slipped into the socket to restore movement and create the new joint.

Shoulder Replacement - Reverse
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 this 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.
