Reverse Shoulder Joint Replacement
Reverse Total Shoulder Replacement is an alternative surgery for patients who have torn their rotator cuffs and have developed severe arthritis or who have had a previous total shoulder replacement that has failed.The primary goal is pain relief and the secondary goal is improved range of motion.
Rotator cuff consists of group of four tendons that join the head of the humerus (arm bone) to the deeper muscles and provides stability and movement to the shoulder joint.
The surgery is done under regional or general anesthesia. An incision is made over the affected shoulder to expose the shoulder joint. In standard total shoulder replacement a metal ball is placed at top of upper arm bone and a plastic socket replaces the arthritic socket. However, in a reverse totalshoulder replacement, the metal ball is attached to the original socket side of the shoulder and a plastic socket is placed at the top of the upper arm bone.
By switching the prosthetics, the patient will now be able to use their strongdeltoid muscle, instead of the torn rotator cuff, to lift their arm. After the artificial components are implanted the joint capsule is stitched and the wound is closed.
Reverse Total Shoulder Replacement surgery is performed through anopen incision similar to that of a standard Total Shoulder Replacement. It usually involves a hospital stay of 2-3 days.
