Rotator Cuff Injury
Rotator Cuff Injury Overview
The rotator cuff is made up of four muscles that help move and stabilize the shoulder joint. Damage to any one of the four muscles or their ligaments that attach the muscle to bone can occur because of acute injury, chronic overuse, or gradual aging. This can cause significant pain and disability with range of motion or use of the shoulder joint.
The shoulder is a ball-socket joint that allows the arm to move in many directions. It is made up of the humeral head (the upper end of the bone of the upper arm) fitting into the glenoid fossa of the scapula (shoulder blade). The humeral head is kept in place by the joint capsule and labrum, thick bands of cartilage that form an elongated cone where the humeral head fits. The rotator cuff muscles are the dynamic stabilizers and movers of the shoulder joint and adjust the position of the humeral head and scapula during shoulder movement.
When the rotator cuff is damaged, a variety of issues arise:
The severity of injury may range from a mild strain and inflammation of the muscle or tendon, that will lead to no permanent damage, to a partial or complete tear of the muscle that might require surgery for repair.
