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 ...
X-rays do not show tendons or the bursae but may be helpful in ruling out bony abnormalities or arthritis. The doctor may remove and test fluid from the inflamed area to rule out infection. Ultrasound scans are frequently used to confirm a suspected tendinitis or bursitis as well as rule out a tear in the rotator cuff muscles.

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.
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 ]
Impingement syndrome can be diagnosed by a targeted medical history and physical examination, [11] [12] but it has also been argued that at least medical imaging [13] (generally X-ray initially) and/or response to local anesthetic injection [14] is necessary for workup. However, imaging studies are unable to show cause of shoulder pain in ...
These include the subacromial, prepatellar, retrocalcaneal, and pes anserinus bursae of the shoulder, knee, heel and shin, etc. (see below [broken anchor]). [1] 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.
