What is Subacromial Decompression?
Four muscle-tendon units compose the rotator cuff within the shoulder joint. These units provide joint stability and shoulder rotation, as well as a connection between the humerus (upper arm bone) and the scapula (shoulder blade). The rotator cuff muscles travel underneath the acromion, a portion of the scapula, as they travel to the humerus. The bursal (tiny fluid-filled sac that functions as a gliding surface to reduce friction between bones, tendons, and muscles around a joint) tissue in this area may become inflamed, known as bursitis, or bone spurs may develop, and cause mechanical irritation and pinching of the tendon, known as impingement. Overuse of the shoulder joint and the natural aging process are responsible for many cases of impingement and bursitis. Patients suffering from either of these shoulder conditions may benefit from a shoulder impingement treatment called subacromial decompression, offered by Vail, Aspen, Colorado Springs and Denver, Colorado area orthopedic shoulder surgeon Dr. Matthew Provencher.
How to Perform Subacromial Decompression
Dr. Provencher performs subacromial decompression under regional or general anesthesia on an out-patient basis in many cases. The arthroscopic procedure requires Dr. Provencher to create a tiny incision in the affected area so he can gain access to the joint, remove the inflamed bursa, and any other irritated soft tissue in the acromion.
Cases of impingement will also be treated with the same technique, but with Dr. Provencher additionally removing bone spurs, and any other bony abnormalities responsible for pinching. Patients suffering from advanced AC joint arthritis and pain may benefit from this shoulder impingement treatment. In these patients, Dr. Provencher will remove a small portion of the clavicle’s distal bone to alleviate pain and other troublesome symptoms.
After all areas of inflamed tissue and bone spurs are removed with subacromial decompression, Dr. Provencher will gently move the shoulder through a series of motions to confirm all areas causing pain and pinching are removed. He will then close the incision site with a simple suture, dress the repaired area, and place the arm in a sling or similar device to immobilize the joint and protect the repair.
