Rotator cuff submitted to significantly greater load and stress, and performs its mainfunctional role. The tendons at the ends of the rotator cuff muscles can become torn, leading to pain and restricted movement of the arm. A torn rotator cuff can occur following a trauma to the shoulder or it can occur through the "wear and tear" on tendons, most commonly the supraspinatus tendon found under the acromion. Rotator cuff injuries are commonly associated with motions that require repeated overhead motions or forceful pulling motions. Such injuries are frequently sustained by athletes whose actions include making repetitive throws, athletes such as baseball
Rotator cuff tear in frequency with age and the most common cause is age-related degeneration and, less frequently, sports injuries or trauma. Some risk factors of experiencing a rotator cuff tear cannot be changed: age, body mass index, and height. Recurrent lifting and overhead motions are at risk for rotator cuff tears. People who have jobs that involve overhead work, such as carpenters, painters, custodians and servers are at risk of also experiencing a rotator cuff tear. People who play sports that involve overhead motions, such as swimming, volleyball, baseball, tennis, and American football quarterbacks, are at a greater risk of experiencing a
