Answer

Subacromial bursitis is frequently associated with supraspinatus tendinitis because inflammation extends from one structure to the other. Repetitive activities with an elevated arm most frequently cause inflammation of the bursae. Examples of this include frequent pitching of a baseball or lifting luggage overhead. Less commonly, a primary process, such as rheumatoid arthritis, gout, or tuberculosis, may lead to bursitis.

Patients often exhibit tenderness over the greater tuberosity. Difficulty in abduction may occur, specifically from 70° to 100°.
