Modified Jobe Approach With Docking Technique for Ulnar Collateral Ligament Reconstruction.

ABSTRACT: The ulnar collateral ligament (UCL) of the elbow acts as the primary restraint to valgus force experienced in the late cocking and early acceleration phases of overhead throwing. If the UCL or dynamic flexor-pronator musculature is incompetent, elbow extension and valgus torque, as seen in throwing, can result in posteromedial impingement with subsequent chondromalacia and osteophyte formation. Before the first UCL reconstruction, performed by Frank Jobe in 1974, this injury was considered career ending in overhead athletes. Since the index procedure, further techniques have been developed to minimize dissection of the flexor-pronator mass and improve the biomechanical strength of graft fixation with the goal of increased return to athletic competition. We describe our technique-including pearls and pitfalls, as well as advantages and disadvantages-which combines the docking technique, through a flexor muscle-elevating approach with transposition of the ulnar nerve using a fascial sling. Harvest and preparation of a palmaris longus tendon autograft is also described.
