Lateral Collateral Ligament Complex of the Elbow

From WikiSM

Description

The lateral collateral ligament complex. The lateral collateral ligament complex consists of the lateral ulnar collateral ligament (LUCL), radial collateral ligament (RCL), and annular ligament. The LUCL runs from the lateral epicondyle and inserts on the supinator crest of the ulna and is the most important stabilizer against varus instability.[1]
