Calcific Tendinopathy of the Rotator Cuff What is it? The rotator cuff refers to a group of four small muscles which run from the shoulder blade to the top of the arm bone. They support and move the shoulder joint. The rotator cuff muscles attach to the arm bone by tendons. Calcific tendinopathy refers to the laying down of calcium deposits within one or more of these tendons. How does it happen? The cause of calcific tendinopathy is not clear. However, it may result from overuse or injury to a rotator cuff tendon. The most commonly involved tendon is that of the supraspinatus muscle. This muscle helps to raise the arm into the air. Its tendon passes through a small space between the top of the arm bone and the point of the shoulder. In this space the tendon is susceptible to ‘wear and tear’. Repetitive use of the supraspinatus muscle and, therefore, the supraspinatus tendon can rub the tendon against the edges of the bony space. This can stimulate the laying down of calcium deposits within the tendon and also cause inflammation or swelling of the tendon. How does it feel? Calcific tendinopathy results in pain felt in the upper arm and over the shoulder. The pain is often intense such that it feels like a toothache-like pain in the shoulder. It is often present when the arm is at rest and made worse by movement of the arm. What should you do? Calcific tendinopathy often does not get better if it is not treated. Therefore, if you have or

suspect you have calcific tendinopathy you should consult our physiotherapists. What shouldn’t you do? If you have or suspect you have calcific tendinopathy, you shouldn’t ignore the problem. This may lead to your injury getting worse. If this occurs your recovery may be prolonged. Could there be any long-terms effects? Calcific tendinopathy does not usually produce any long-term effects as long as it is properly diagnosed and appropriately treated. If not, it can lead to prolonged pain in the upper arm and a prolonged lay-off from participation. In some situations, this may occur despite appropriate treatment. In these cases, surgery may be required to remove the calcium deposits and to alleviate your pain. Management The assistance of a sports physiotherapist is important in the treatment of calcific tendinopathy. Initially, they can assist in diagnosing the problem and its severity. This may require the use of imaging techniques such as an X-ray or MRI. From this, the sports physiotherapist will be able to determine an appropriate treatment plan. This may initially involve techniques to reduce your pain. These may include activity modification, the taking of anti-inflammatory medications, and in some cases, the injection of a small amount of anti-inflammatory directly into the affected tendon.
