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

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.
