Rotator Cuff
Supraspinatus Infraspinatus Teres Minor Subscapularis


The top rotator cuff tendon, known as the supraspinatus, is responsible for raising the arm to the side and is the most commonly torn rotator cuff tendon.


The infraspinatus lifts the arm to the side and helps to externally rotate. It is frequently torn in conjunction with the supraspinatus.

Teres Minor

The back rotator cuff tendon, called the teres minor, is responsible for externally rotating the arm. Tears to this tendon almost always occur with larger tears to other tendons.


The front rotator cuff tendon, the subscapularis, is the largest and strongest of the tendons and is responsible for internally rotating the arm as well as holding the biceps tendon in place.
