SYMPTOMS

Associated with bcp deposits in tendons and bursae, most commonly around theshoulder (particularly rotator cuff), but can occur around almost any joint. Acute Calcific periarthritis presents with sudden onset of severe pain, swelling, tenderness, and restricted motion, with overlying redness and warmth.

CAUSES

Tiny crystals of hydroxyapatite sometimes form in or around joints and can cause inflammation of joints and tissues around the joints, such as tendons and ligaments. They have been described particularly as a cause of rotator cuff inflammation of the shoulder.
