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.

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 ...
Diagram of normal bursae surrounding the shoulder joint: (1) subacromial-subdeltoid bursa, (2) subscapular recess, (3) subcoracoid bursa, (4) coracoclavicular bursa, (5) supra-acromial bursa and (6) medial extension of subacromial-subdeltoid bursa.
An x-ray showing calcific deposits in the area of the tendons of the rotator cuff muscles. Calcific tendinitis is typically diagnosed by physical examination and X-ray imaging. [1] During the formative phase, X-ray images typically reveal calcium deposits with uniform density and a clear margin. [1]
However, imaging studies are unable to show cause of shoulder pain in diagnosing. For example, MRI imaging would show rotator cuff pathology and bursitis but is unable to specify the cause. [15] On physical exam, the physician may twist or elevate the patient's arm to test for reproducible pain (the Neer sign and Hawkins-Kennedy test).
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 ...
Medical history (the patient tells the doctor about an injury). For shoulder problems the medical history includes the patient's age, dominant hand, if injury affects normal work/activities as well as details on the actual shoulder problem including acute versus chronic and the presence of shoulder catching, instability, locking, pain, paresthesias (burning sensation), stiffness, swelling, and ...
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] Since the bursa is supra-acromial, not supraclavicular, fluid-filled masses located over the acromioclavicular joint or distal clavicle do not correspond ...
