What is Subacromial Decompression?
The rotator cuff is composed of four muscle-tendon units that play a vital role in providing stability and rotation to the shoulder joint. These units connect the humerus, or the upper arm bone, to the scapula, or the shoulder blade. The rotator cuff muscles travel beneath the acromion, which is a portion of the scapula, on their way to the humerus. Inflammation of the bursal tissue in this area, also known as bursitis, or the development of bone spurs, can cause mechanical irritation and pinching of the tendon, which is called impingement. Many cases of bursitis and impingement are caused by overuse of the shoulder joint and the natural aging process.
How to Perform Subacromial Decompression?
Dr. Nawaid Ahmed often performs subacromial decompression as an outpatient procedure under either regional or general anesthesia. This arthroscopic surgery involves creating a small incision in the affected area to access the joint, remove the inflamed bursa and other irritated soft tissue in the acromion. For patients with impingement, Dr. Nawaid Ahmed will also remove bone spurs and any other bony abnormalities responsible for pinching. This impingement treatment can also benefit those with advanced AC joint arthritis and pain. In such cases, Dr. Nawaid Ahmed will remove a small part of the clavicle’s distal bone to relieve pain and other symptoms.
Once all areas of inflamed tissue and bone spurs are removed during subacromial decompression, Dr. Nawaid Ahmed will test the shoulder by gently moving it through a range of motions to ensure that all areas causing pain and pinching are removed. Then he will close the incision site using 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.
Frequently Asked Questions(FAQ's)
Subacromial decompression is an arthroscopic surgical procedure aimed at relieving shoulder pain caused by impingement syndrome. The surgery involves removing inflamed bursal tissue and bone spurs beneath the acromion (part of the shoulder blade) to create more space for the rotator cuff tendons, thereby reducing irritation and improving shoulder movement.
The procedure has a high success rate in relieving pain and improving shoulder function, especially when conservative treatments have failed. Many patients experience significant improvement in symptoms and quality of life post-surgery.
The duration of the surgery varies depending on the complexity of the case but generally lasts between 30 to 60 minutes.
High-impact or contact sports, such as weightlifting with heavy overhead loads, rugby, or cricket fast bowling, may put stress on the shoulder and are usually discouraged permanently. Low-impact activities like swimming, cycling, yoga, or walking are generally safe once recovery is complete, provided you follow your physiotherapist’s guidance.
