本研究的目的是建立正确的诊断脊髓内病变的位置和范围的情况下，连续型或混合型骨化的后纵韧带和估计术后预后诱发脊髓电位（ESCP）。从1985年至1987年接受手术并随访6个月以上的26例患者，使用传导性ESCP进行检查，显示下肢，肠和膀胱功能，节段性ESCP和皮节段性ESCP显示上肢功能。将五极记录电极置于颈部硬膜外腔。传导性ESCP的刺激部位为胸段硬膜外腔，节段性ESCP的刺激部位为手肘正中神经，皮节段性ESCP的刺激部位为手指表面。在狭窄的颈椎管中部ESCP消失的病例中，将另一个刺激电极放置在枕大池中，并记录下行传导ESCP以监测脊柱病变的上缘。新的发现，不能观察到的X线片，脊髓造影，CT扫描，使用这种技术是可检测的。
The purpose of this study is to establish the correct diagnosis of the location and extent of intraspinal cord lesions in cases of continuous or mixed-type ossification of the posterior longitudinal ligament and to estimate the postoperative prognosis using evoked spinal cord potentials (ESCP). Twenty-six patients, who underwent surgery from 1985 to 1987 and who have been followed for more than 6 months, were examined using a conductive ESCP, which demonstrates lower extremity, bowel, and bladder function, and a segmental ESCP and dermatome segmental ESCP, which demonstrate upper extremity function. A five-pole recording electrode was placed in the cervical epidural space. The stimulation sites were the thoracic epidural space for conductive ESCP, the median nerve at the elbow for the segmental ESCP, and the finger surface for the dermatome segmental ESCP. In cases in which the ESCP disappeared at the middle of the narrow cervical spinal canal, another stimulating electrode was placed in the cisterna magna, and a descending conductive ESCP was recorded to monitor the upper border of the spinal lesion. New findings, which could not be observed by roentgenograms, myelography, and CT scan, were detectable using this technique.
