肌电图对腰椎间盘突出症手术前后检测结果分析

ANALYSIS OF EMG ON PATIENTS WITH THE PROLAPSE OF LUMBAR INTERVERTEBRAL DISK BEFORE AND AFTER OPERATION

目的:根据腰椎间盘突出症患者手术前后的肌电图表现,了解肌电图定位与手术相符合程度及手术前后神经根压迫程度的变化。方法:使用日本充电MEB—5404K型肌电一诱发电位仪对34例腰椎间盘突出症患者进行手术前后肌电图检查。结果:术前肌电图检查提示的神经根受损部位与手术中所见相符率为94.1％。术后肌电图显示神经根受压程度明显减轻。结论:肌电图对腰椎间盘突出症的神经根受压有定位价值及对术后效果有一定的评价作用。

Objective:According to EMG manifestations of the pstients with pro-lopse of lumbar intervertebral disk before and after the operation,we want to know the consistent degree of operation between localization of EMG and surgery and its change before and after the operation.Method:using the MEB 5304K type instrument of EMG and evoked potential,34 patients with the prolapse of lumbar intervertebral disk were performed to examine EMG before and after the operation.Results:The coincident rate of the injured nervous roots which were showed by EMG examined before operation was 94.1 percent.The pressed degree of nervous roots was markedly reduced after operation.Conclusion:The EMG is useful for the localization of injured nervous roots as well as for the evaluation of operation results.
