Supraspinatus tendon
Tendo musculi supraspinati
Definition
The supraspinatus tendon is a tendon of the rotator cuff, with two portions: the anterior half is long and thick; the posterior half is short and thin.
The footprint of the supraspinatus insertion on the greater tubercle of humerus takes only the most anterior portion, in the shape of a triangle that is wider anteriorly, and frequently it has an additional extension with fibers crossing over the transverse ligament and bicipital groove with its biceps tendon and inserting into the lesser tuberosity.
