Lateral Ulnar Collateral Ligament Reconstruction for Posterolateral Rotatory Instability of the Elbow

Reconstruction of the lateral ulnar collateral ligament of the elbow is the primary treatment for recurrent symptomatic posterolateral rotatory instability. Although a number of lateral ulnar collateral ligament reconstruction techniques have been described, the docking technique has received general acceptance. In this technique, the graft is passed through a tunnel on the ulnar side and the 2 free limbs are docked into the humerus at the isometric point on the lateral condyle. Advantages of this method of reconstruction include reduced bone removal, decreased soft tissue damage, and precise control of graft tensioning. When precise surgical steps are followed, this technique can be performed in a reliable, efficient, and reproducible manner for patients with posterolateral rotatory instability of the elbow.
