b"oReverse Shoulder Replacement A reverse shoulder replacement is a design in which the positions of the ball and socket are switched: A metal ball implant is placed where the patient's own natural socket was, and a plastic socket implant is placed on the head of the humeral head. This reverse design has more stability and it is commonly performed on patients who have shoulder arthritis with a severe rotator cuff tear.
