Reverse Shoulder Replacement

What is Reverse Shoulder Replacement?

Conventional surgical methods such as total shoulder joint replacement are not very effective in the treatment of rotator cuff arthropathy. Reverse total shoulder replacement is an advanced surgical technique specifically designed for rotator cuff tear arthropathy, a condition where you suffer from both shoulder arthritis and a rotator cuff tear.

Differences between Conventional and Reverse Shoulder Replacement

Conventional shoulder replacement surgery involves replacing the ball of the humerus with a metal ball and the glenoid cavity of the shoulder blade (scapula) with a plastic socket. If this surgery is used to treat rotator cuff arthropathy, it may result in implant loosening due to the torn rotator cuff. Therefore, a specifically designed surgery was developed called reverse total shoulder replacement to be employed in such cases.

In reverse total shoulder replacement, the placement of the artificial components is essentially reversed. In other words, the humeral ball is placed in the glenoid cavity of the shoulder blade (scapula) and the plastic socket is placed on top of the arm bone. This design makes efficient use of the deltoid muscle, the large shoulder muscle, to compensate for the torn rotator cuff.

Ideal candidates for Reverse Shoulder Replacement

Reverse total shoulder replacement may be recommended for the following conditions:

• Completely torn rotator cuff that is difficult to repair
• Presence of rotator cuff tear arthropathy
• Previous unsuccessful shoulder replacement
• Severe shoulder pain and difficulty in performing overhead activities
• Continued pain despite other treatments such as rest, medications, cortisone injections and physical therapy

Reverse Shoulder Replacement Procedure

Reverse total shoulder replacement surgery is performed under general anesthesia.
