Abstract: Nerve transposition is to rebuild the nerve function of the injured site and restore partial sensory and motor functions in patients with spinal cord injury paralysis by transposing the autologous peripheral nerve with secondary or compensatory functions and suturing with the nerves in the key part of the injury sites. A comprehensive understanding of the mechanism, development, operation and indications of nerve transposition in the treatment of spinal cord injury paralysis is necessary for clinical treatment. This study reviewed the main nerve transposition techniques for functional reconstruction of spinal cord injury paralysis in the literatures at home and abroad, so as to provide reference for the treatment of spinal cord injury paralysis.
