供体神经的选择-周围神经端侧吻合的重要因素

目的探索周围神经端侧吻合时供体神经的选择。方法新西兰大白兔30只,随机分3组,每组10只。A组：端端吻合组,切断尺神经,端端吻合。B组：切断尺神经,与正中神经端侧吻合。C组：切断尺神经,与桡神经端侧吻合。各组分别于术后3月取材进行组织学、形态定量学和电生理检测。结果端端吻合组优于其他两组。余两组差异无统计学意义。结论原位端端吻合是神经损伤最佳修复方式。支配两组拮抗肌的神经行端侧吻合后有神经纤维再生。

Selection of the donor nerve an important factor in side anastomosis of peripheral nerve

Objective To explore the selection of the donor never in side anastomosis of peripheral never. Methods 30 New Zealand white rabbits were ramdomly divided into 3 groups in group B. Transected the ulnar nerve,and end-to-end neurorrhaphy in group A. Transected the ulnar nerve,and end-to-side neurorrhaphy the median nerve. Transected the ulnar nerve,and end-to-side neurorrhaphy the radial nerve in group C. Histological,morphological and electrophysiological examinations were performed 3 months after the operation. Results End to end anastomosis group was better than others. There was no significant differences between group B and group C. Conclusion End to end anastomosis is the best way to repair the nerve injury. The nerve fiber regenerate in end-to-side anastomosis between the nevers which innervate two groups of antagonistic muscle.
