Novel Technique for Ulnar Nerve Transposition at the Elbow: The Neocubital Tunnel

Many standard surgical procedures for cubital tunnel syndrome rely on ulnar nerve transposition at the elbow. Placing the ulnar nerve anterior to the axis of motion decreases compression during flexion. Subcutaneous, subfascial, and submuscular positioning of the ulnar nerve may predispose to nerve irritation, instability, and compression in the two first scenarios, and requires invasive dissection in the third one. With no single procedure demonstrating clear advantages and outcomes, this study reports the results of a novel technique using the epitrochleo-olecranon ligament to create a neo-tunnel, anatomically stabilizing the ulnar nerve.
