目的：对18例患者总计突出颈椎间盘28个,比较不同牵引方向对颈椎间盘突出症(HCD)的颈椎功能变化规律。
方法：借助MRI影象扫描研究不同牵引方向对颈椎突出间盘的运动、脊髓受压指数、椎间隙的变化及伴有变性病例的作用。
结果：不同的牵引方向对间盘突出的作用是有差异的,屈曲牵引使间盘部分还纳最为明显。脊髓受压指数在屈曲方向牵引最低。伸展牵引时椎间盘突出缩小组的后缘椎间隙减小明显。屈曲牵引时椎间盘缩小组与无变化组的后缘变化差异不大,两种牵引方向对前缘影响均无差异。各种方向牵引伴有变性者的形态变化不明显。
结论：HCD改变了正常椎关节的微细形态结构,对常规牵引方向的规律宜灵活运用。脊髓受压指数比间盘突出大小更能反映脊髓受损的实质。牵引对伴有变性者意义可能不大。 |

Abstract:
Objective:To compare the fuctional and morphological changes of the cervical spine of 18 patients (28 disci herniations) under different directions in herniation of cervical disc (HCD).
Methods:To study the effect of different directions of traction on the movement of herniated disc,compression index of spinal cord,changes of intervertebral space and the influence on cases with degeneration by MRI.
Results:There were differences among the effects of traction in different directions.Most significant partial retraction of the herniated disc was experienced in flexion traction.Both flexion and extension traction caused marked reduction of index of compression of spinal cord.Extension traction resulted in marked narrowing of the posterior edge of intervertebral space in the group with disc size reduction,but there was not much difference between the groups with and without disc size reduction under flexion traction.There was no marked effect on the morphological changes in cases with degeneration in any direction of traction.
Conclusion:HCD changed the fine morphological structures of normal vertebral joints.The direction of traction should be selected according to condition of the individual case.The compression index could reflect the nature of spinal cord injury better than size of disc protrusion.Traction will not give much benefit in cases with degeneration. |
