非神经组织桥接神经缺损的远期观察

Long term follow-up study of peripheral nerve bridge with non-nerve tissue

对非神经组织桥接周围神经缺损的疗效进行远期观察．共治疗７例８条神经，正中神经３条，桡、尺神经各２条，胫神经１条。缺损长度为３～６ｃｍ，均采用非神经组织桥接。全部得到５～７年的随访，膜类管状物桥接的２条疗效优良，带蒂骨骼肌桥接的６条神经疗效差，这和肌细胞的组织结构可能阻止再生轴突的生长有关．我们认为膜类管状物桥接疗效较骨骼肌为好．

We conducted long term follow-up study to evaluate the effects of non-nerve tissue bridge tech nique in peripheral nerve repair.Seven patients of peripheral nerve defects including 3 median nerves,2 radial nerves,2 ulnar nerves and 1 tibial nerve were treated with non-nerve tissue bridges. The gaps between nerve ends ranged from 3 to 6 cm. All cases had been followed up for 5 to 7 years. The outcomesof the 2 cases using empty membrane tube was satisfactory. The outcomes was poor in 6 nerves usingpedicled skeltal muscle bridge.The remained histological structure of muscle cell may prevent thegrowth of regenerated a-con. Caution should be taken in choosing non--nerve tissue to bridge the gap ofperipheral nerve.
