Anatomy of rotator cuff tendon

The rotator cuff is a group of tendons and muscles in the shoulder, connecting the upper arm (humerus) to the shoulder blade (scapula). The rotator cuff tendons provide stability to the shoulder; the muscles allow the shoulder to rotate.

The muscles in the rotator cuff include:

Teres minor

Infraspinatus

Supraspinatus

Subscapularis

nkshoulderdoc-subscapularis
