What is a Reverse Shoulder Replacement?
Shoulder arthritis is a degenerative condition responsible for chronic joint pain, weakness, and limited mobility in millions of Americans. The shoulder condition is fairly common in the older population and typically develops after a shoulder injury or from wear and tear of the joint gradually over time. At the beginning of arthritis treatment, many patients will be prescribed non-surgical measures to alleviate pain and other troublesome symptoms. Conservative measures are successful in certain patients, while other patients require a surgical intervention if the condition progresses. Vail, Aspen, Colorado Springs and Denver, Colorado area orthopedic shoulder surgeon, Dr. Matthew Provencher offers a specific technique of shoulder replacement surgery, known as reverse shoulder replacement, to help return patients to an active lifestyle when all other treatment measures have failed.
When to Have Reverse Shoulder Replacement
Dr. Provencher generally recommends a reverse shoulder replacement in patients who suffer from a complex form of shoulder arthritis known as rotator cuff tear arthropathy. Rotator cuff tear arthropathy occurs when the muscles that help center the ball (head of the humerus) in the socket (glenoid portion of the shoulder blade) move higher than the socket because of a long established rotator cuff tear.
A traditional shoulder replacement surgery depends on the rotator cuff muscles to keep the replacement components in place and provide movement, and is typically reserved for shoulder arthritis patients. A reverse shoulder replacement depends on the deltoid muscle for mobility and stability. A reverse procedure is effective in many patients with rotator cuff tear arthropathy, a rotator cuff tear that cannot be repaired and a failed shoulder replacement surgery.
How is a Reverse Shoulder Replacement Different from a Shoulder Replacement?
A reverse shoulder replacement is very similar to a traditional shoulder replacement surgery since both procedures require Dr. Provencher to replace the degenerated cartilage and bone within the shoulder joint with metal and medical-grade plastic components. This shoulder replacement technique changes the overall mechanics of the joint by allowing the deltoid muscle to move and stabilize the joint. In a normal, healthy shoulder joint, the rotator cuff is responsible for stabilization and movement.
Dr. Provencher begins this shoulder replacement surgery technique by creating a small incision in the front area of the joint. He will then remove the natural, degenerated cartilage and bone, and replace it with synthetic components. The reverse shoulder replacement involves a reversal of the ball and socket. Dr. Provencher will place the ball on the glenoid (normally the socket) and the socket on the humerus (normally the ball). The result is pain-free, fluid movement of the shoulder joint in most patients.
