Rotator Cuff Injury

What is a rotator cuff injury?

The shoulder is one of the most mobile joints in the body, and as such it needs stabilising structures to make sure it stays in place (and not dislocate!). The rotator cuff is one of these structures. It consists of four separate muscles around the shoulder joint, and the tendons of these muscles which attach to the upper arm bone (humerus). When the muscles of the rotator cuff flex, they pull the ball of the shoulder joint closer in to the socket of the shoulder joint.

Damage to the muscles and tendons of the rotator cuff is a very common cause of shoulder pain.
