The rotator cuff is comprised of four muscles or major tendons including the supraspinatus, infraspinatus, teres minor, and subscapularis. Rotator cuff tears are the most common injuries to the shoulder. Doctors can perform test such as the movement of you're shoulder to determine which or all tendons that may be involved and the severity of the injury. Treatment can include steroid injection shots, physical therapy and sometime surgery to reattach the muscle back to the bone.
