Case:
The lateral ulnar collateral ligament (LUCL) is one of the primary stabilizers of the elbow. Disruption typically occurs from the humeral origin and may be because of an elbow dislocation or fracture/dislocation. If not identified and properly managed, posterolateral rotatory instability may result from LUCL insufficiency. We describe the case of a patient with bipolar LUCL disruption consisting of an avulsion fracture of the crista supinatoris and a soft-tissue avulsion from the lateral epicondyle.
Conclusion:
Bipolar disruption of the LUCL is a previously unreported injury pattern that may lead to posterolateral instability if not identified and treated.
