The Docking Technique: Lateral Ulnar Collateral Ligament Reconstruction for Posterolateral Rotatory Instability

February 10, 2018

Posterolateral rotatory instability of the elbow occurs after injury to the lateral ulnar collateral ligament. Symptomatic posterolateral rotatory instability is characterized by subluxation of the radiocapitellar joint with posterior and valgus displacement. The patient often will complain of elbow instability when extending a loaded, supinated elbow. If nonsurgical treatment, such as activity modification, immobilization, and physical therapy, does not improve symptoms, then restoration of the lateral ligamentous complex is required. Except in patients with acute trauma, reconstruction often is required given the chronic nature of the injury and poor tissue quality. This video reviews the background of posterolateral rotatory instability and comprehensively outlines the pearls and surgical workflow for lateral ulnar collateral ligament reconstruction.
