终板及终板下骨质在MRI上的信号改变与颈椎关节突关节退变的关系

The relationship between the Modic changes of bone of the endplate and sub-endplate on magnetic resonance imaging and cervical articular process degeneration

目的探讨终板及终板下骨质在MRI上的信号改变(Modic改变)与颈椎关节突关节退变的关系。方法对98例颈椎病患者C_(2~7)节段(共490个节段)进行CT和MRI检查。观察颈椎关节突关节退变程度、Modic改变、颈椎间盘退变程度的关系。结果①颈椎关节突关节退变:最常见于C_(4~5)节段,最少见于C_(2~3)节段。②Modic改变:最常见于C_(6~7)节段,最少见于C_(2~3)节段。但Modic改变与颈椎关节突关节退变不相关。③颈椎间盘退变:根据Miyazaki分级系统,颈椎同一节段的关节突关节退变、Modic改变在分级较高的椎间盘退变中较常见。结论颈椎关节突关节退变最常见于C_(4~5)节段,Modic改变最常见于C_(6~7)节段,颈椎关节突关节退变和Modic改变在Miyazaki分级较高的颈椎间盘退变中更常见。但Modic改变与颈椎关节突关节退变不相关。

Objective To explore the relationship between Modic changes of bone of endplate and sub-endplate on magnetic resonance imaging(MRI)and cervical articular process degeneration.Methods CT and MR examination were performed on 98 patients with cervical spondylosis at C_(2~7) segment(490 segments)in order to observe the relationship between the degeneration degree of articular process of the cervical spine,Modic changes,and the degeneration degree of cervical intervertebral disc.Results①Cervical articular process degeneration was the most common at C_(4~5) and the least common at C_(2~3).②Modic changes were the most common at C_(6~7) and the least common at C_(2~3).But Modic changes were not associated with cervical articular process degeneration.③According to Miyazaki classification system,articular process degeneration and Modic changes in the same segment of the cervical spine were more common in higher classification of intervertebral disc degeneration.Conclusions Cervical articular process degeneration is most common at C_(4~5),and Modic changes are most common at C_(6~7),articular process degeneration and Modic changes are more common in higher Miyazaki classification of cervical intervertebral disc degeneration.But there is no association between Modic changes and cervical articular process degeneration.
