Subacromial IMPINGEMENT is a condition where the inflammed bursa and/or the rotator cuff tendon is pinched between the humeral head and the undersurface of the acromion. A subacromial decompression can open up this space by removing any swollen or inflamed bursa, and any bony spurs using keyhole surgery(arthroscopy).
The rotator cuff is a group of four muscles that come together as tendons to form a “cuff” over the head of the humerus (upper arm bone). The rotator cuff helps to lift and rotate the arm and to stabilize the ball of the shoulder within the joint. Surgery to repair a torn rotator cuff tendon most often involves re-attaching the tendon to the head of humerus (upper arm bone).
The Shoulder joint is a “ball and socket” joint. When the head of the humerus (ball) dislocates, the glenoid bone (socket) and the ligaments in the front of the shoulder are often injured. The labrum — the cartilage rim around the edge of the glenoid — may also tear. The unstable shoulder joint can be repaired using arthroscopic (keyhole) surgery. The purpose of the surgery is to repair the torn/stretched capsule and the labrum so that they are better able to hold the shoulder joint in place.
