Rotator cuff tears happen in the tissues that support your shoulder. Your rotator cuff is a set of tendons of four muscles that come together at your shoulder blade. These muscles wrap around the top of a bone called the humerus. This helps to hold the top part of your humerus in your shoulder socket.
