Abstract
Background The rabbit sciatic nerve injury model may represent a valuable alternative for critical gap distance seen in humans but often leads to automutilation. In this study, we modified the complete sciatic nerve injury model for avoiding autophagy. Materials and Methods In 20 adult female New Zealand White rabbits, instead of transecting the complete sciatic nerve, we unilaterally transected the tibial portion and preserved the peroneal portion. Thereby loss of sensation in the dorsal aspect of the paw was avoided. The tibial portion was repaired in a reversed autograft approach in a length of 2.6 cm. In an alternative repair approach, a gap of 2.6 cm in length was repaired with a chitosan-based nerve guide. Results During the 6-month follow-up period, there were no incidents of autotomy. Nerve regeneration of the tibial portion of the sciatic nerve was evaluated histologically and morphometrically. A clear difference between the distal segments of the healthy contralateral and the repaired tibial portion of the sciatic nerve was detectable, validating the model. Conclusion By transecting the isolated tibial portion of the rabbit sciatic nerve and leaving the peroneal portion intact, it was possible to eliminate automutilation behavior.
期刊介绍:
JBPPNI is an open access, peer-reviewed online journal that will encompass all aspects of basic and clinical research findings, in the area of brachial plexus and peripheral nerve injury. Injury in this context refers to congenital, inflammatory, traumatic, degenerative and neoplastic processes, including neurofibromatosis. Papers on diagnostic and imaging aspects of the peripheral nervous system are welcomed as well. The peripheral nervous system is unique in its complexity and scope of influence. There are areas of interest in the anatomy, physiology, metabolism, phylogeny, and limb growth tropism of peripheral nerves.
