Reverse Total Shoulder Replacement
A reverse total shoulder replacement may be considered in patients suffering severe joint arthritis with irrepairable rotator cuff tears or patients with a deficient rotator cuff suffering superior migration of the humeral head. Another consideration for a reverse total shoulder replacement may include malunion of a proximal humeral fracture or an irrepairable proximal humeral fracture.
The prosthesis used in a reverse total shoulder replacement is similar to a total shoulder replacement, however the prosthesis is reversed. Instead of the ball on the end of your humerus a socket is placed and instead of the socket on your shoulder blade (glenoid) a ball, or glenosphere, is placed. Hence the socket and the ball are reversed.
