Abstract

  Anterior interosseous to ulnar motor nerve transfer offers a viable solution in the management of high ulnar nerve injuries. Following clinical observation, we sought to determine if supercharged anterior interosseus nerve (AIN) to ulnar motor nerve transfer confers a clinically significant improvement in functional outcome as measured by the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Our objective was to track the functional outcomes compared to baseline following supercharged AIN to ulnar motor nerve transfer in patients with high ulnar nerve injuries. A case series comprising a retrospective cohort included all patients who underwent an anterior interosseous to ulnar motor nerve transfer within a one-year time interval. Functional outcomes were assessed via the preoperative to postoperative change in outcome measures including DASH scores, hand strength and active range of motion. Sixteen patients were included in the final review (81.25% male, 18.75% female, mean age 54.81 ± 16.26 years) with a mean follow-up of 2.06 ± 0.892 months. Postoperative DASH scores for all combined injury etiologies, compressive etiologies, and traumatic etiologies decreased an average of 41.99%, 29.38% and 88.23% respectively. Grip strength, 3-point pinch strength, and lateral pinch strength increased an average of 41.37%, 16.38% and 55.84% respectively. Ulnar deviation and radial deviation increased an average of 46.38% and 31.58% respectively. Our findings demonstrate that end-to-side AIN to ulnar motor nerve transfer for ulnar nerve injuries may be a powerful adjunct to traditional management of above elbow nerve injuries.
