One of the most frequent causes of shoulder pain is the damage of the rotator cuff tendon. Its etiology is multifactorial and the symptoms often require prompt medical intervention. The glenohumeral joint is one of the largest and most complex joints in the human body, so it is very important to understand the many anatomical and pathological variations which may occur. One of such pathological variations is shoulder pain, which might be the result of an unusual rupture of the supraspinatus muscle. In this article we report a rare case of tearing of this muscle and creating of an additional attachment on the lesser tubercle. Moreover, the body produced a bursa that lines the inner layer of the shoulder skin. This work is needed by clinicians because it shows how, despite the massive damage to the muscle and the cartilage structures, the passive range of motion is maintained, and it also shows the role of the synovial bursa in the pathophysiology process. It is very important to learn more about anatomical and pathological variations in order to properly manage shoulder pain and dysfunctions.
