Rotator crescent

The rotator crescent is the crescent-shaped, thin area of the distal supraspinatus and infraspinatus tendons, which are two major rotator cuff tendons. On its medial border is a thick fibrous reinforcement called the rotator cable.

It is hypothesized that the rotator crescent is shielded from mechanical stress by the rotator cable, which is about 2.5 times the thickness of the tendinous tissue in the rotator crescent .
