Reinnervation after microsurgical repair of transected cauda equina fibres: An electromyographic study

Abstract

Ventral nerve roots of the lumbar area in seven pigs were transected intradurally and resutured microsurgically immediately after transection. Four to seven months after repair electromyography was done via intradural electric stimulation of the resutured roots. Reinnervation was found. Patterns were compared with data from intact animals.

Neural reconstruction methods of restoring bladder function

“…The field of neurourology has advanced considerably since these first attempts. Strategies, such as end-to-end root repair, 23, 25, 26, 36, 53, 54 intradural root-to-root crossover repair, 15, 27, 35 spinal-nerve-to-root crossover repair, 22, 24, 30, 42 or the reverse root-to-spinal-nerve repair, 37, 38, 40, 41 direct detrusor reinnervation, 32 transfer of peripheral somatic or autonomic nerves to vesical branches of the pelvic nerve, 17–21, 29, 33–36 and even creation of artificial skin–CNS–bladder pathways, 43–47, 66–68 have been developed to improve the management of NBD based on the concept that axons have the capacity to regenerate in the peripheral and central nervous systems.…”

The clinical study of repairing cauda equina fibres with fibrin glue after lumbar fracture and dislocation

“…It was supported by somatosensory evoked potential results. 13 No amplitude was recorded from tibial and peroneal nerves in any of the patients. As to femoral nerves, no amplitude was recorded in six patients.…”
