A member asked:

Why is the suprasipatus muscle the most frequently involved muslce in rotator cuff injuries?

A doctor has provided 1 answer

Blood supply: The supraspinatus is most commonly torn for a couple of reasons. First, the tendon gets blood supply from attachment site on bone, and from muscle. Between these is a watershed area where blood supply is limited. Allows for more rapid tendon degradation. Next, it is subject to pathologic contact with the undersurface of the acromion, known as impingement.
