摘　　要：目的:探讨神经电生理检测对臀部肌注致坐骨神经损伤的诊断意义.方法:对34例患者进行腓总神经、胫神经的神经传导速度(NCV)检测,并对胫骨前肌、腓肠肌、股二头肌长短头、椎旁肌L4～S1进行针极肌电图检测.结果:34例病例中,腓总神经传导速度NCV异常29例(85.3%),胫神经13例(38.2%),腓总神经、胫神经同时异常8例(23.5%).经统计学处理,与正常对照组比较差异有显著意义(P＜0.01).肌电图示,有失神经电位改变者:胫前肌为29例(85.3%),股二头肌短头为29例(85.3%),腓肠肌为13例(38.2%),股二头肌长头为13例(38.2%).结论:神经电生理检测对臀部肌注致坐骨神经损伤的诊断可提供客观依据.Objective： To explore the significance of electoneurophysiological detection for sciatic nerve damage in patients with gluteal muscle injection. Methods：The nerve conduction velocity （NCV）of the common peroneal and the tibial nerve were studied and the needle electrode electromyograms （EMG） of the musculis tibialis anterior, gastrocnemius, biceps femoris and sacros pinalis L4--S1 were analized in 34 the patients. Results： Of the 34 patients,the abnormality was noted in 29 ones （85.3%） in the peroeal NCV,13 （38.2%） in the tibialis NCV, and 8（23.5%） ones with peroneal and tibialis. Significant difference（P〈0.01） in the NCV was found between the normals and the patients. The EMG findings were as follows ：fasciculation potentials were recorded in 29 patients（85.3 % ）in musculis tibialis anterior and biceps short head, 13（38.2% ） in musculis gastrocnemius,and biceps long head. Conclusion： Electroneurophysiological detection might provide objective evidence for the diagnosis of the sciatic nerve damage in the patients with gluteal muscle injectioin.
