Targeted Muscle Reinnervation as a Solution for Nerve Pain

Abstract

Symptomatic injured nerves resulting from amputations, extremity trauma, or prior surgery are common and can decrease patient quality of life, thus necessitating an effective strategy for management. Targeted muscle reinnervation is a modern surgical strategy for prevention and treatment of neuroma pain that promotes nerve regeneration and healing rather than neuroma formation. Targeted muscle reinnervation involves the transfer of cut peripheral nerves to small motor nerves of adjacent, newly denervated segments of muscle and can be easily performed without specialized equipment. Targeted muscle reinnervation strategies exist for both upper and lower extremity amputations and for symptomatic neuromas of intact limbs. Targeted muscle reinnervation has been shown in a prospective, randomized, controlled trial to result in lower neuroma and phantom pain when compared to the historical gold standard of burying cut nerves in muscle.
