A rotator cuff is a group of tendons in the shoulder joint that provides support and enables a wide range of motion. A major injury to these tendons may result in rotator cuff tears. It is one of the most common causes of shoulder pain in middle-aged and older individuals.
A rotator cuff tear may occur with repeated use of the arm for overhead activities, while playing sports, or from a motor accident.
A rotator cuff tear causes severe pain, weakness of the arm and crackling sensation on moving the shoulder in certain positions. There may be stiffness, swelling, loss of movement and tenderness in the front of the shoulder.
