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. [1]
The subacromial bursa is the synovial cavity located just below the acromion, which communicates with the subdeltoid bursa in most individuals, forming the so-called subacromial-subdeltoid bursa (SSB).
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 ...
Inflammation and subsequent thickening of the subacromial bursa may also cause impingement. [2] Weight training exercises where the arms are elevated above shoulder height but in an internally rotated position such as the upright row have been suggested as a cause of subacromial impingement. [7]
Bursitis is commonly caused by repetitive movement and excessive pressure. Shoulders, elbows and knees are the most commonly affected. Shoulders, elbows and knees are the most commonly affected. Inflammation of the bursae may also be caused by other inflammatory conditions such as rheumatoid arthritis , scleroderma , systemic lupus ...
The supra-acromial bursa is located on the superior aspect of the acromion and normally does not communicate with the glenohumeral joint. [1] Supra-acromial bursitis has not been receiving much attention from literature and remains described mainly as case reports of presumptive diagnosis with no histopathological correlation. [ 2 ]
The subcoracoid bursa does not communicate with the glenohumeral joint under normal circumstances, but may communicate with the subacromial bursa. [1] As such, contrast fluid injected into the glenohumeral joint during an arthrogram that extends into the subcoracoid bursa is abnormal, and indirectly implies a full thickness rotator cuff tear. [2]
Localized pain on the anterior shoulder suggests subacromial impingement, whereas posterior shoulder pain suggests internal impingement. [45] For the diagnosis of full-thickness rotator cuff tear, the best combination appears to include once more the painful arc and weakness in external rotation, and in addition, the drop arm sign .
