Brachioradialis Flap With Vascularized Lateral Ulnar Collateral Ligament Reconstruction: A Case Report.

Background: Soft tissue defects about the elbow with concurrent ligamentous instability can be challenging to treat. Methods: We present a case report of a lateral elbow wound that resulted in lateral ulnar collateral ligament deficiency and posterolateral elbow instability. Results: We describe our technique of a modified brachioradialis rotational flap, in which the muscle is rotated to cover the soft tissue defect, while the vascularized brachioradialis tendon is used to simultaneously reconstruct the lateral ulnar collateral ligament. This procedure successfully restored posterolateral elbow stability at the time of wound coverage. Conclusion: Elbow soft tissue defects with associated ligamentous injuries can be treated using a modification of the brachioradialis rotational flap.
