Abstract

OBJECTIVES

Analysis of the relationship between the symptoms, digital nerve somatosensory evoked potentials (D-SEP) and MRI, in patients with symptomatic cervical spine disorders (CSD).

MATERIALS AND METHODS

MRI and D-SEP following electrical stimulation of digits I, III and V in 44 patients.

RESULTS

Symptoms in the fingers correlated significantly with disk herniation at the corresponding cervical level and with spinal cord impingement at one or two adjacent rostral segments on MRI. D-SEP was abnormal in 52% of all patients. Among them, the groups with multiple and single level involved on MRI had 62% and 30% of abnormal somatosensory evoked potentials (SEP), respectively. Digit I-SEP abnormality was more often localized at the root level, while digit V-SEP at the spinal cord level above the dorsal nucleus. D-SEP correlated best with compression of the spinal cord at adjacent upper and especially the most rostral (C3-5) levels on MRI.

CONCLUSIONS

Accurate correlation of D-SEP and symptoms with MRI is essential for correct localization of lesions in patients with CSD.

摘要

目的

分析有症状的颈椎疾病（CSD）患者的症状、指神经体感诱发电位（D-SEP）与MRI之间的关系。

材料与方法

对44例患者的示指、中指和小指进行电刺激后行MRI和D-SEP检查。

结果

手指症状与MRI上相应颈椎节段的椎间盘突出以及一个或两个相邻头侧节段的脊髓受压显著相关。所有患者中52%的D-SEP异常。其中，MRI显示多节段和单节段受累的患者中，体感诱发电位（SEP）异常的分别占62%和30%。示指SEP异常多定位于神经根水平，而小指SEP异常多定位于背核上方的脊髓水平。D-SEP与MRI上相邻上位尤其是最头侧（C3-5）节段的脊髓受压相关性最佳。
