One hundred twenty-three cases of cervical spondylotic and ossification of the posterior longitudinal ligament (OPLL) myelopathy cases with long tract signs subjected to surgical treatment were studied to identify the most important factors having an influence on postoperative outcome using evoked spinal cord potentials (ESCP). Disappearance and positive wave changes of these potentials at the level of responsible lesions and slow conduction velocity under 40 m indicated an unsatisfactory outcome. Localized-lesion cases diagnosed by ESCPs had excellent results, significantly more so than extensive-lesion cases, regardless of operative methods. In 123 cases, 76% were found to have localized lesions, while the other 24% showed extensive lesions. Concerning the difference between CSM and OPLL, 54% of OPLL and only 14% of CSM demonstrated extensive lesions.
对123例患有颈椎病和后纵韧带骨化（OPLL）脊髓病且伴有长束征并接受手术治疗的病例进行研究，以确定使用脊髓诱发电位（ESCP）对术后结果产生影响的最重要因素。这些电位在责任病灶水平的消失和正波变化以及传导速度低于40米/秒表明预后不佳。无论手术方法如何，通过ESCP诊断为局限性病灶的病例效果极佳，明显优于广泛性病灶的病例。在123例病例中，发现76%为局限性病灶，而另外24%为广泛性病灶。关于颈椎病脊髓型（CSM）和OPLL之间的差异，54%的OPLL病例和仅14%的CSM病例表现为广泛性病灶。
