what is the ucl ligament

The ulnar collateral ligament (UCL) is a ligament located on the medial side of the elbow that connects the upper arm bone (humerus) to a bone in the forearm (ulna) . It is made up of three ligaments: the anterior oblique, posterior oblique, and transverse ligaments. UCL injuries can occur due to overuse or trauma, and are commonly found in baseball pitchers and other athletes that throw. Symptoms of a UCL injury include medial elbow pain, valgus instability, and impaired throwing. UCL injuries are diagnosed by physical examination and imaging tests such as X-rays and MRI scans. Treatment for UCL injuries ranges from rest and physical therapy to surgery, depending on the extent of the UCL tear and the patients health goals.
