This is from massgeneral.org

Surgical nerve repair involves exploration of the injured nerve and removal of injured tissue or scar from the nerve endings. After that, a nerve can be directly reconnected if there is enough length on the ends to allow for a good quality repair without tension.

Another website says after healing begins the nerves regrow and “reach out” to stimulate the surrounding tissue allowing for reattached limbs to work.
