Abstract

Summary: Sensory nerve trauma at the level of the wrist can lead to debilitating neuromas. Targeted muscle reinnervation (TMR) is an effective therapy for the treatment of neuromas. Here we propose the use of the terminal anterior interosseous nerve (AIN) as a viable recipient for TMR. All superficial sensory nerves around the wrist, including the dorsal ulnar sensory nerve, the distal lateral antebrachial cutaneous nerve, the distal branches of the superficial branch of the radial nerve, and the palmar cutaneous branch of the median nerve were dissected in 2 cadaver specimens. The AIN branch to pronator quadratus was divided just distal to the final branch of flexor pollicis longus to preserve adequate length for TMR. The sensory nerves at the wrist were fully dissected to identify a viable location for coaptation to the AIN. After the cadaveric concept was demonstrated, the technique was successfully used in a clinical case. In summary, the distal AIN is a versatile recipient for TMR as a treatment of painful sensory neuromas at the level of the wrist, with minimal donor-site morbidity.
