The Super-Turbocharged End-to-Side Abductor Digiti Minimi and Anterior Interosseous Double Nerve Transfer Is Associated With Improved Ulnar Intrinsic Function.

ABSTRACT:

Background

Nerve transfers to reinnervate ulnar intrinsic musculature can restore function in severe ulnar neuropathy, and supercharged end-to-side (SETS) nerve transfers have garnered early adoption. Given the relative expendability of the abductor digiti minimi (ADM), redirecting its axons to more critical components of the ulnar motor nerve (UMN) in a turbocharged end-to-side (TETS) nerve transfer with concomitant anterior interosseous SETS nerve transfer (AIN) as a super-turbocharged end-to-side (STETS) or twin-charged double nerve transfer may improve functional recovery.

Methods

A retrospective study of patients undergoing the STETS AIN/ADM to UMN double nerve transfer or TETS ADM to UMN nerve transfer for severe ulnar neuropathy between 2020 and 2022 was performed. Pr
