The ulnar collateral ligament (UCL) can become stretched, frayed or torn through the stress of repetitive throwing motions, causing ulnar collateral ligament injuries.
Professional pitchers have been the athletes treated most often for this problem. Javelin throwers and football, racquet sports, ice hockey, and water polo players have also been reported to injure the UCL. A fall on an outstretched arm can also lead to UCL rupture (often with elbow dislocation).
