supercharge end to side anterior interosseous to ulnar motor nerve transfer restores intrinsic function in cubital tunnel syndrome
Plastic and Reconstructive Surgery, 2020Co-Authors: Jana Dengler, Andrew Yee, Lorna C. Kahn, Utku Can Dolen, Jennifer Megan M Patterson, Kristen M Davidge, Susan E. MackinnonAbstract:Background The supercharge end-to-side anterior interosseous nerve-to-ulnar motor nerve transfer offers a viable option to enhance recovery of intrinsic function following ulnar nerve injury. However, in the setting of chronic ulnar nerve compression where the timing of onset of axonal loss is unclear, there is a deficit in the literature on outcomes after supercharge end-to-side anterior interosseous nerve-to-ulnar motor nerve transfer. Methods A retrospective study of patients who underwent supercharge end-to-side anterior interosseous nerve-to-ulnar motor nerve transfer for severe cubital tunnel syndrome over a 5-year period was performed. The primary outcomes were improvement in first dorsal interosseous Medical Research Council grade at final follow-up and time to reinnervation. Change in key pinch strength; grip strength; and Disabilities of the Arm, Shoulder and Hand questionnaire scores were also evaluated using paired t tests and Wilcoxon signed rank tests. Results Forty-two patients with severe cubital tunnel syndrome were included in this study. Other than age, there were no significant clinical or diagnostic variables that were predictive of failure. There was no threshold of compound muscle action potential amplitude below which supercharge end-to-side anterior interosseous nerve-to-ulnar motor nerve transfer was unsuccessful. Conclusions This study provides the first cohort of outcomes following supercharge end-to-side anterior interosseous nerve-to-ulnar motor nerve transfer in chronic ulnar compression neuropathy alone and underscores the importance of appropriate patient selection. Prospective cohort studies and randomized controlled trials with standardized outcome measures are required. Clinical question/level of evidence Therapeutic, IV.

evaluation of intrinsic hand musculature reinnervation following supercharge end to side anterior interosseous to ulnar motor nerve transfer
Plastic and Reconstructive Surgery, 2020Co-Authors: Linden K Head, Zach Z Zhang, Katie E Hicks, Gerald Wolff, Kirsty U BoydAbstract:Supercharge end-to-side anterior interosseous-to-ulnar motor nerve transfer is commonly performed in the authors' institution to augment intrinsic hand function. Following observations of recovery patterns, the authors hypothesized that despite its more distal innervation, the first dorsal interosseous muscle recovers to a greater extent than the abductor digiti minimi muscle. The objective of this work was to evaluate the clinical and electrodiagnostic pattern of reinnervation of intrinsic hand musculature following supercharge end-to-side anterior interosseous-to-ulnar motor nerve transfer. A retrospective cohort of prospectively collected data included all patients who underwent a supercharge end-to-side anterior interosseous-to-ulnar motor nerve transfer. Two independent reviewers performed data collection. Reinnervation was assessed with two primary outcome measures: (1) clinically, with serial Medical Research Council strength assessments; and (2) electrodiagnostically, with serial motor amplitude measurements. Statistical analysis was performed using nonparametric statistics. Seventeen patients (65 percent male; mean age, 56.9 ± 13.3 years) were included with a mean follow-up of 16.7 ± 8.5 months. Preoperatively, all patients demonstrated clinically significant weakness and electrodiagnostic evidence of denervation. Postoperatively, strength and motor amplitude increased significantly for both the first dorsal interosseous muscle (p = 0.002 and p = 0.016) and the abductor digiti minimi muscle (p = 0.044 and p = 0.015). Despite comparable preoperative strength (p = 0.098), postoperatively, the first dorsal interosseous muscle achieved significantly greater strength when compared to the abductor digiti minimi muscle (p = 0.023). Following supercharge end-to-side anterior interosseous-to-ulnar motor nerve transfer, recovery of intrinsic muscle function differs between the abductor digiti minimi and the first dorsal interosseous muscles, with better recovery observed in the more distally innervated first dorsal interosseous muscle. Further work to elucidate the underlying physiologic and anatomical basis for this discrepancy is indicated. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.
