What is the rotator cuff?The rotator cuff is the group of four tendons that stabilize the shoulder joint. The tendons hook up to the four muscles that move the shoulder in various directions. There are four muscles whose tendons form the rotator cuff: the subscapularis muscle, which moves the arm by turning it inward (internal rotation); the supraspinatus muscle, which is responsible for elevating the arm and moving it away from the body; the infraspinatus muscle, which assists the lifting of the arm during turning the arm outward (external rotation); and the teres minor muscle, which also helps in the outward turning of the arm.

Calcific Bursitis
- Calcific bursitis is the calcification of the bursa caused by chronic inflammation of the bursa. Calcific bursitis most commonly occurs in the shoulder. Calcific bursitis treatment includes medication for inflammation, ice, immobilization, cortisone injections, and occasionally surgical removal of the inflamed bursa.

Hydroxyapatite Crystal Disease
- Hydroxyapatite crystal disease is the inflammation caused by hydroxyapatite crystals. These tiny crystals of hydroxyapatite deposit by mistake in or around joints and may cause inflammation of the joints and nearby tissues such as the tendons and ligaments (particularly causing rotator cuff problems in the shoulder). Treatment options include rest, cold application, medications to reduce inflammation, and cortisone-related medication injections.
