Ulnar Collateral Ligament
WHAT IS THE ULNAR COLLATERAL LIGAMENT?
The ulnar collateral ligament (UCL) is a stabilizer on the inside of the elbow. It is the most commonly injured ligament in throwers but can be injured in falls or other high-energy injuries.
Injury to the UCL can range from inflammation to partial tearing to complete tears of the ligament. Athletes often first notice pain and decreased throwing velocity.
Treatment depends on the degree of injury and one’s activity level. Complete rest from throwing can be the best treatment for some while others may need surgery to reconstruct the elbow.
