Tears of the lateral collateral ligament lead to a condition referred to as postero-lateral rotatory instability of the elbow [33,34]. Tears of the lateral collateral ligament in young individuals usually are the result of an elbow dislocation. Tears of the lateral collateral ligament in adults most commonly are caused by a varus extension stress injury to the elbow that does not result in elbow dislocation . Most tears of the lateral collateral ligament are full-thickness tears that involve the proximal attachment of the ulnar band to the lateral epicondyle [33,35]. Disruption of the ulnar band of the lateral collateral ligament also can occur following overaggressive release of the common extensor tendon origin for treatment of lateral epicondylitis [33-35].
MRI of the elbow may be useful in evaluating the lateral collateral ligament. The lateral collateral ligament is visualized best on coronal Tl-weighted and proton density weighted MRI images. The ulnar band of the lateral collateral ligament appears as a thin band of low signal intensity that extends along the lateral joint line of the elbow and then crosses posterior to the radial head to insert onto the proximal ulna (Fig. 13). Only one study has described the MRI findings in patients with tears of the lateral collateral ligament. All patients showed abnormal signal intensity at the proximal attachment of the ulnar band of the lateral collateral ligament to the lateral epicondyle (Fig. 14) .
