Sixteen consecutive patients who were unable to ambulate independently due to cervical spondylotic myelopathy were treated surgically with the guidance of spinal cord evoked potentials (SCEPs). The SCEPs were recorded intraoperatively with needle electrodes inserted into serial cervical intervertebral discs after caudal epidural stimulation. Despite the presence of multiple extradural defects and/or cord compression seen on MRI, anterior decompression followed by fusion was able to be focused on a single level where the distinct change in waveform of the SCEP suggestive of spinal conduction block was revealed. Excellent neurological improvement resulted from the operation and all patients followed up for a period of more than 6 months were found to be ambulatory without walking aids.
16例因脊髓型颈椎病而无法独立行走的连续患者在脊髓诱发电位（SCEPs）引导下接受了手术治疗。术中通过在骶管硬膜外刺激后将针电极插入连续的颈椎间盘来记录SCEPs。尽管MRI显示存在多个硬膜外缺损和/或脊髓受压，但前路减压融合术能够聚焦于SCEP波形出现明显变化提示脊髓传导阻滞的单一节段。手术带来了极佳的神经功能改善，所有随访超过6个月的患者均能在无需助行器的情况下行走。
