Nerve grafting is a surgical methodology employed to bridge discontinuities in damaged peripheral nerves, serving as a critical area of research focused on investigating strategies for promoting axonal regeneration, re-establishing target tissue innervation, and optimizing functional recovery following traumatic or iatrogenic nerve transection. This field encompasses the study of autologous nerve grafts, allografts, synthetic conduits, and biological factors aimed at enhancing nerve repair outcomes and restoring lost sensory and motor function.
