What is the Rotator Cuff and what does it look like? The rotator cuff is the grouping of all four muscles that hold the ball on the socket in the shoulder. The big muscles just under the skin move the arm around in all directions. The rotator cuff is deep. The wing bone, or scapula, is where the rotator cuff muscles originate. The attachment is on the ball, or the humeral head. Over the top of the rotator cuff is the roof bone, or acromion. The roof bone sometimes has a spur on it. Really this spur is an excessive prominence that can rub the bursa and the tendons of the rotator cuff. Some rubbing causes pain and bursitis. More rubbing and more time with the bursitis leads to inflammation of the rotator cuff tendons. A tear can develop in time or with a trauma, such as a fall.

ALL THE SAME VIEWS AS ABOVE EXCEPT THE BLUE AREA IS THE BURSA. NOTE THE ROOF BONE OVER THE TOP, CALLED THE ACROMION. THE ACROMION TIP IN THE FRONT IS WHERE THE SPUR OR PROMINENCE IS LOCATED.
