The rotator cuff is a group of four tendons that attach their shoulder muscles to the top of the bone in the upper arm and together help to stabilise the shoulder. They are: supraspinatus; infraspinatus; teres minor and subscapularis. The most commonly affected tendons are supraspinatus and infraspinatus but all the rotator cuff tendons may be involved in impingement syndrome.
Problems with the rotator cuff tendons may be due to injury or overuse and physiotherapy can usually help as outlined under the individual tendinopathy below.
