Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle.

If conservative measures are unsuccessful, surgery can be trialed. Surgery to cut the adhesions (capsular release) may be indicated in prolonged and severe cases; the procedure is usually performed by arthroscopy. Surgical evaluation of other problems with the shoulder, e.g., subacromial bursitis or rotator cuff tear, may be needed.
These deposits are common in rotator cuff tendinopathy and are most frequently found in the supraspinatus tendon (63% of the time), and less frequently in the infraspinatus tendon (7%), subacromial bursa (7%), subscapularis tendon (3%), or in both the supraspinatus and subscapularis tendons at the same time (20%).
Calcific bursitis refers to calcium deposits within the bursae. This most occurs in the shoulder area. The most common bursa for calcific bursitis to occur is the subacromial bursa. A bursa is a small, fluid-filled sac that reduces friction, and facilitates movements between its adjacent tissues (i.e., between tendon and bone, two muscles or ...
Surgery may be done arthroscopically or as open surgery. The impinging structures may be removed in surgery, and the subacromial space may be widened by resection of the distal clavicle and excision of osteophytes on the under-surface of the acromioclavicular joint. [4] Damaged rotator cuff muscles can be surgically repaired.
In arthritis of the shoulder, the cartilage of the ball and socket (glenohumeral joint) is lost so that bone rubs on bone. It may be caused by wear and tear (degenerative joint disease), injury (traumatic arthritis), surgery (secondary degenerative joint disease), inflammation (rheumatoid arthritis) or infection (septic arthritis).

The SSB bursa is located deep to the deltoid muscle and the coracoacromial arch and extends laterally beyond the humeral attachment of the rotator cuff, anteriorly to overlie the intertubercular groove, medially to the acromioclavicular joint, and posteriorly over the rotator cuff.
Symptoms vary from localized warmth and erythema (redness) [1] to joint pain and stiffness, to stinging pain that surrounds the joint around the inflamed bursa. [citation needed] Bursitis could possibly also cause a snapping, grinding or popping sound – known as snapping scapula syndrome – when it occurs in the shoulder joint. This is not ...
