Intercostal nerve transfer to lumbar nerve roots. Part I: development of an animal model and cadaver studies.

This is a description of the development of an animal model for intercostal nerve transfer and saphenous nerve grafting to lumbar nerve roots in the dog. Further, the technical feasibility of intercostal nerve transfer and autogenous sural nerve grafting to the lumbar and sacral nerve roots in the adult and infant human cadaaver is demonstrated graphically.
