Reverse Shoulder Replacement

What is a Reverse Shoulder Replacement?

The Reverse Shoulder Replacement is a special kind of shoulder replacement.

A Shoulder Replacement is surgery to replace the bones of the shoulder joint with artificial joint parts.

Your shoulder joint is a type of ball and socket joint. The ball is the end of your humerus (upper arm bone) called your humeral head and the socket is part of your shoulder blade (scapula) called your glenoid. This type of joint allows your shoulder to be very flexible and allows you to have a great range of movement with your shoulder and arm.

During a total shoulder replacement, the round ball of your arm bone (humeral head) and the socket (glenoid) are replaced.

A normal shoulder replacement uses a metal ball on the top of the arm bone (humerus), and a plastic / metal socket on the shoulder blade (scapula). This is similar to how our body is designed with a ball-and-socket shoulder joint.

The reverse shoulder replacement uses a ball-and-socket joint as well, but their positions are 'reversed'. That is, the ball is placed on the shoulder blade (scapula), and the socket is placed on top of the arm bone (humerus).
