UCL Injury Overview. The ulnar collateral ligament (UCL) of the elbow is a structure that is critical for elbow stability. The UCL is a triangular, thick section of tissue that maintains a healthy and normal valgus relationship between the arm bone (humerus) and the ulna (one of the bones found in the forearm). An ulnar collateral ligament injury can range from a mild stretch to a full tear. An ulnar collateral ligament tear is usually the result of a sports injury that involves repetitive overuse associated with pitching or throwing.
