体感诱发电位对神经根型颈椎病手术效果的预测价值

摘要

Objective To evaluate the neurological function of cervicalspondylotic radiculopathy by somatosensory evoked potentials (SEP) and provide an objective basis for selecting the best operation occasion. Methods 60 patients with C6 and C7 radiculopathies were di-vided into 3 groups according to the results of SEP:normal group (n=22), mildly abnormal group (n=30) and severely abnormal group (n=8). All the patients underwent anterior cervical decompression and fusion. They were assessed with Neck Disability Index (NDI) before and after treatment. Results The postoperative NDI scores of all the groups improved significantly (P<0.001), especially in the normal group. Conclusion SEP, which can reflect the severity of cervicalspondylotic radiculopathy objectively and predict prognosis.%目的：应用体感诱发电位(SEP)评估神经根型颈椎病患者的神经功能状态，为掌握最佳手术时机提供客观依据。方法根据SEP将60例C6、C7神经根受累的颈椎病患者分为正常组22例、轻度异常组30例和重度异常组8例。入选患者均接受颈椎前路减压植骨融合术。手术前后分别进行颈椎功能障碍指数(NDI)评分。结果术后正常组、轻度异常组、重度异常组患者NDI评分与术前相比均有显著恢复(P<0.001)，且正常组恢复最佳。结论 SEP能够客观反映神经根型颈椎病病变的严重程度，提示手术预后。
