坐骨神经及其分支损害的临床电生理分析

目的回顾性分析坐骨神经及其分支损害的病因及电生理表现。方法结合70例患者病因,分析腓神经和胫神经传导速度及健、患侧胫骨前肌、腓肠肌针电极肌电图表现。结果外伤导致的有36例(51%),其次是肌肉注射,占20例(29%),外科手术并发5例(7%),不明原因9例(13%)。单纯腓神经损害25例,单纯胫神经损害13例,坐骨神经损害32例。结论外伤是本组坐骨神经及其分支损伤的主要原因,电生理检测对确定受损神经、损害性质、损害程度及评价预后有重要价值。

Clinical and electrophysiologicai analysis of sciatic nerve injury

Objective To analyze retrospectively the clinical and electrophysiological findings of injuries in sciatic nerve and its branches. Methods We analyzed the etiological factors of seventy patients as well as the peroneal and tibial nerve conduction and the needle elcetromyographic examinations in muscles of tibialis anterior and gastrocnemius. Results Trauma was the most commonly cause of sciatic nerve damage (36/70), followed by muscle injection (20/70), then the surgery complications (5/70) and finally by the unidentified (9/70). The impairments of sciatic nerve alone, peroneal nerve alone and tibial nerve alone accounted for 32 cases, 25 cases and13 cases, respectively. Conclusion Trauma is the most common cause of sciatic nerve damage. The electrophysiological studies may demonstrate much significance in evaluating injured nerve, features, severity and prognosis of the injuries.
