摘　　要：目的:分析腰椎间盘突出症(LDH)患者的肌电图(EMG)与CT影像学特征。方法:选取2020年6月-2024年5月荆州市第三人民医院收治的90例LDH患者作为研究对象,均行EMG、CT检查。分析其影像特征,并与手术结果进行对照,分析其诊断符合率。结果:EMG显示,LDH患者患侧胫神经、腓总神经的末端潜伏期较健侧延长,患侧胫神经、腓总神经的波幅均小于健侧,差异有统计学意义(P<0.05)。CT可发现LDH患者的髓核游离椎管内且呈萎缩/瘢痕化,黏连状、山丘等突出物状,手术部位与EMG、CT结果符合率较高。术后LDH患者患侧胫神经、腓总神经的末端潜伏期均缩短,波幅均增加,差异有统计学意义(P<0.05)。疗效优、良者术前患侧胫神经、腓总神经的末端潜伏期短于疗效可或差者,差异有统计学意义(P<0.05)。疗效优、良者患侧胫神经、腓总神经的波幅更大,差异有统计学意义(P<0.05)。疗效可、差者髓核游离椎管内、额状位突出c~d域、硬膜囊受压移位等比例均较疗效优、良者更高,差异有统计学意义(P<0.05)。结论:LDH患者EMG及CT均有一定的影像学特征,且其与手术结果符合率均较高,二者也可用于评估疗效。Objective:To analyze electromyography(EMG)and CT imaging features of patients with lumbar disc herniation(LDH).Method:90 LDH patients admitted to the Third people's Hospital of Jingzhou from June 2020 to May 2024 were selected as the study objects,and all of them underwent EMG and CT examination.The imaging features were analyzed and compared with the surgical results to analyze the diagnostic coincidence rate.Result:EMG showed that the terminal latency of tibial nerve and common peroneal nerve on the affected side of LDH patients was longer than that on the healthy side,and the amplitude of tibial nerve and common peroneal nerve on the affected side was smaller than that on the healthy side,and the difference was statistically significant(P<0.05).CT showed that the nucleus pulposus was free in the spinal canal of LDH patients and was atrophied/scarring,with protrusion such as adhesion and hill,etc.The coincidence rate between the surgical site and the results of EMG and CT were higher.The terminal latency of tibial nerve and common peroneal nerve on the affected side of LDH patients was shortened and the amplitude was increased,and the difference was statistically significant(P<0.05).The terminal latency of tibial nerve and peroneal nerve on the affected side was shorter in patients with excellent and good curative effect than in patients with fair or poor curative effect,and the difference was statistically significant(P<0.05).The amplitude of tibial nerve and peroneal nerve on the affected side was greater in patients with excellent and good curative effect,and the difference was statistically significant(P<0.05).The proportion of free nucleus pulposus in vertebral canal,frontal protrusion in c~d region,dural sac compression and displacement were higher in patients with good or fair curative effect,and the difference was statistically significant(P<0.05).Conclusion:Patients with LDH have certain EMG and CT features which are coincident with surgical results.The two can also be used to evaluate therapeutic effe
