Rotator Cuff Tendons Have a Naturally Poor Blood Supply
Full Title
The vascularity of the rotator cuff.
Summary
This review examined the blood supply to the rotator cuff tendons and its role in injury and degeneration. The researchers identified that the major arteries supplying the rotator cuff come from several branches around the shoulder. Most importantly, they found a "critical zone" in the supraspinatus tendon where blood supply is naturally limited. This area of poor circulation is believed to contribute significantly to the wear and degeneration of the tendon as we age, making it harder for the body to heal injuries in this region. The findings support the importance of stimulating blood flow to the rotator cuff to support healing, especially in areas where natural circulation is already compromised.
