The rotator cuff is a group of muscles and tendons that attach to the bones of the shoulder joint, allowing the shoulder to move and keeping it stable.
The tendons of the rotator cuff pass underneath a bony area on their way to attaching to the top of the arm bone. These tendons join together to form a cuff that surrounds the shoulder joint. This helps keep the joint stable and allows the arm bone to move on the shoulder bone.
