The 'failed back' represents a major clinical problem. Among the causes recognized for the 'failed back' is lateral root stenosis which has led to the use of electromyography (EMG) in the diagnosis of root compression. One hundred and thirty-two patients selected for surgical decompression were compared with 25 undergoing spinal fusion. EMG was found to be diagnostic in 95% of patients with bony canal stenosis, but only gave positive results in 62.5% of prolapsed disc patients. EMG improved in those patients who made a good recovery after surgery.
“手术失败的背部”是一个重大临床问题。在“手术失败的背部”的公认病因中，侧隐窝狭窄导致了肌电图（EMG）在神经根受压诊断中的应用。将132例选择进行手术减压的患者与25例接受脊柱融合术的患者进行比较。发现EMG对95%的骨性椎管狭窄患者具有诊断价值，但对仅62.5%的椎间盘突出患者给出阳性结果。术后恢复良好的患者，其EMG结果有所改善。
