Function of the ulnar collateral ligament (UCL), and what are its components?
The UCL, also known as the medial collateral ligament (MCL), is a focal thickening of the medial joint capsule. It stabilizes the medial aspect of the elbow and resists valgus stress. The UCL is comprised of three components: the anterior bundle, posterior bundle, and oblique band (also known as the transverse ligament).
