Understand How your Shoulder Works

A joint is formed by the ends of 2 or more bones that are connected by thick bands of tissue called ligaments. The shoulder typically involves 2 bones:

  • The scapula (shoulder blade)
  • The humerus (upper arm bone)

The rotator cuff – 4 muscles connecting the humerus with the scapula – supplies stability and balance to the shoulder joint. Proper rotator cuff balance is essential for arm raising and rotation. When you raise your arm, the rotator cuff holds the humeral head tightly within the socket (glenoid) of the scapula. Learn More
