Lateral Collateral Tear

The elbow is a complex joint of the upper limb formed by the articulation of the long bone of the upper arm or humerus and the two bones of the forearm, namely, radius and ulna. The elbow joint is supported by the ulnar collateral ligament, radial collateral ligament and the annular ligament. These ligaments provide stability and strength to the elbow joint. Lateral ulnar collateral ligament is the main stabilizer on the outside of the elbow. Tear of this ligament is known as the lateral ulnar collateral ligament tear. Lateral ulnar collateral ligament may tear due to elbow dislocation.
