A rotator cuff injury is when there is a strain, tear or damage to the one or more of the rotator cuff muscles. It is one of the most common injured areas of the shoulder. The injury usually involves damage to the rotator cuff tendons (The part of the muscle that connect the muscles to bones). By the age of 50 approximately 10% of people will have a rotator cuff tear. A study by Yamamoto showed 20.7% of 1366 shoulders had full-thickness rotator cuff tears in the general population of a mountain village in japan.
