Deposits of calcium may form within a rotator cuff or biceps tendon. This is known as calcific tendonitis.
The cause of this condition is unknown. It usually occurs in middle age.
In over 90 percent of cases, the deposits resolve spontaneously, but this may take 12 to 18 months. Some patients have very little pain, only occurring with movement of the arm, while others can have severe pain throughout the process. Severe pain usually occurs in the resorption process, which is the end stage of the injury. Severe pain can last up to a week. Your physio will assist your recovery through manual therapy to the shoulder, chest and side of your neck. He will trial exercises to determine appropriateness for exercise. Referral to a shoulder specialist will be made if resolution of symptoms is poor. Sometimes the calcium deposit causes damage to the tendon which may need surgical repair. The calcium deposit can also cause impingement syndrome due to thickening of the subacromial bursa. Cortisone injection can be very effective treatment for bursitis. Another recent treatment having some success is extracorporeal shock wave therapy where acoustic waves are directed at the calcium deposit via a sound head to break up the deposit to aid resorption. The important thing to keep in mind is maintaining mobility of the shoulder joint. Adhesive capsulitis AKA frozen shoulder is an unfortunate outcome of the injured shoulder that is not mobilised appropriately
