Abstract:
Objective To explore the origin of the regenerating axons which grow into peroneal nerve after"?" fashion double end to side neurorrhaphy to tibial nerve Methods The right peroneal nerve of Wistar rat was cut about 5mm long segment off, the proximal and distal stumps of it were end to side coapted to the windows, opened by removing the epineual sheath on the tibial nerve trunk with 7～10mm distance At 18 months after the operation, the action potential(AP) between distal segment of peroneal nerve and proximal peroneal/or tibital/or sciatic nerve was tested Aftr that, the distal segment of peroneal nerve was removed and embed by resin, and semithin section and superthin section were observed by light or electronic microscope Results The morphological study clearly revealed that there were correspondent regenerating axons in the distal peroneal nerve segment, meanwhile the AP through the distal peroneal and proximal tibial/or peroneal nerve was measured clearly Conclusion "?" double end to side suturing to tibial nerve fashion neurorrhaphy can cause nerve regeneration from proximal tibial and or proximal peroneal to distal peroneal nerve
