Delayed neural reconstruction in the lower extremity: results of interfascicular nerve grafting.

During a 4-year period, one of the authors (M.B.W.) performed 16 nerve reconstructions by interfascicular grafting in the lower extremities of 13 patients. Three patients were excluded from the study: one was lost to follow-up and two had less than 1-year follow-up. At an average follow-up of 30 months, the results of 13 procedures in 10 patients were evaluated. Results were good after five procedures, fair after five, and poor after three. Superior results were evident with shorter graft lengths and after nerve transection injuries.
