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]
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.

Bursae of shoulder joint: (1) and (6) subacromial-subdeltoid bursa, (2) subscapular recess, (3) subcoracoid bursa, (4) coracoclavicular bursa, (5) supra-acromial bursa. A number of small fluid-filled sacs known as synovial bursae are located around the capsule to aid mobility: Between the joint capsule and the deltoid muscle is the subacromial ...
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 ...
Bursitis is the inflammation of one or more bursae (synovial sacs) of synovial fluid in the body. They are lined with a synovial membrane that secretes a lubricating synovial fluid. [1] There are more than 150 bursae in the human body. [1] The bursae rest at the points where internal functionaries, such as muscles and tendons, slide across bone ...
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 ]
Olecranon bursitis is a condition characterized by swelling, redness, and pain at the tip of the elbow. [ 1 ] [ 2 ] If the underlying cause is due to an infection , fever may be present. [ 2 ] The condition is relatively common and is one of the most frequent types of bursitis .
Third, most partial-thickness cuff tears do not occur on bursal surface fibers, where mechanical abrasion from the acromion does occur. [ 29 ] [ 30 ] Fourth, it has been suggested that bursal surface cuff tears could be responsible for subacromial spurs and not the opposite.
