title: [Which changes occur in nerve grafts harvested with a nerve stripper? Morphological studies].
abstract: A histological and morphometric study was undertaken in order to evaluate the alterations in sural nerves harvested for nerve grafting using a nerve stripper. In 19 nerves biopsies were taken from the proximal and/or the distal end of the stripped nerve graft. Cross sections were examined for alterations of the perineurium and the myelin sheaths. In four nerves alterations within the perineurium were found, which affected 37% of the endoneural cross-sectional area on the average. In all specimens, the perineurial sheath was seen to be intact. The results of the present study suggest that harvesting of a nerve graft using a stripper does not cause major injuries to the graft and therefore successful neurotization of the graft should not be impaired.
