An imaging study was designed to evaluate disc degeneration and segmental instability in the cervical spine.
To compare the magnetic resonance imaging assessment of disc degeneration with the conventional plain radiographic evaluation of cervical segmental instability.
No studies have been conducted to investigate the association of disc degeneration with cervical instability.
Two hundred sixty consecutive patients with suspected cervical spine disorders were analyzed for horizontal and angular displacements on lateral flexion and extension radiographs and disc degeneration on T2-weighted magnetic resonance images of the cervical vertebrae.
In all intervertebral levels, the grade of disc degeneration increased significantly (P < 0.01) with age. Cervical instability was identified in 151 segments (14.5%) and correlated with Grade 1 and Grade 2 degeneration in the intervertebral discs (P < 0.01).
Cervical segmental instability may indicate early degeneration of intervertebral disc in the cervical vertebrae.
设计一项影像学研究以评估颈椎间盘退变和节段性不稳定。
比较椎间盘退变的磁共振成像评估与颈椎节段性不稳定的传统X线平片评估。
尚未有研究调查椎间盘退变与颈椎不稳定之间的关联。
对连续260例疑似颈椎疾病患者进行分析,观察其颈椎侧屈和后伸X线片上的水平和角度位移,以及颈椎T2加权磁共振图像上的椎间盘退变情况。
在所有椎间水平,椎间盘退变程度随年龄显著增加(P < 0.01)。151个节段(14.5%)发现颈椎不稳定,且与椎间盘1级和2级退变相关(P < 0.01)。
颈椎节段性不稳定可能提示颈椎间盘早期退变。
