The rotator cuff is a set of four muscles that serve to stabilize and rotate the shoulder, attached by strong tendons to the upper head of the humerus. During abduction, the supraspinatous and infraspinaoous muscles abduct and rotate the head of the humerus.What is normal shoulder abduction?
Shoulder abduction. Abduction occurs when you have arm movement away from the middle of your body. When you raise your arm out from the sides of your body, it’s an abduction of your shoulder. A normal range for abduction, starting with your palms at your sides, is around 150 degrees in a healthy shoulder.What is the shoulder muscle that abducts the shoulder?
Supraspinatus is the first shoulder muscle to initiate arm shoulder abduction. The supraspinatus can abduct the shoulder for the first 15 degrees (0-15 degrees). The supraspinatus is located on the greater tubercle of the humerus. Deltoid is the second shoulder muscle responsible for arm abduction.
