The ulnar (medial) collateral ligament (UCL) of the elbow consists of three bundles: anterior, posterior, and transverse. Researchers have shown that the anterior bundle is the primary restraint to valgus stress at the elbow.1-8 Ligament injury rarely leads to symptomatic instability.3,9 An exception is UCL injury in an athlete who participates in a sport involving overhead throwing motions, such as javelin or baseball throwing or tennis serving. The extreme valgus loads that the throwing motion generates place tremendous stress across the medial portion of the joint. Subtle injury to the UCL can lead to disabling valgus instability in the throwing athlete who places repetitive valgus stress on the elbow.2,9-15 Instability that prevents the athlete from returning to competition often indicates the need for surgical reconstruction.
