摘要
我们通过３７例腰椎管狭窄症伸屈脊髓造影和１３例腰椎管狭窄症动态ＣＴ扫描，测量分析不同体位下Ｌ３～Ｌ５Ｓ１硬膜囊矢径和Ｌ４，５间隙黄韧带厚度的变化情况，结果显示：Ｌ３、Ｌ３、４、Ｌ４、Ｌ４，５，Ｌ５硬膜囊矢状径屈曲位明显大于后伸位，差异非常显著或显著（Ｐ＜０．００１，Ｐ＜０．０１或Ｐ＜０．０５），Ｌ４，５，间隙黄韧带厚度前屈位明显小于后伸位，差异非常显著（Ｐ＜０．００１）。我们认为屈曲位整脊手法治疗腰椎管狭窄症可以减轻黄韧带对硬膜囊和神经根的压迫，增大硬膜囊矢状径，扩大椎管的有效空间，减少腰椎管的狭窄程度。
Flexion-extension myelography and dynamic CT scan on lumbar spinal stenosis were applied respectively in thirty-seven cases and seventeen cases to analyze the changes of the anterior-posterior widths of the dural sac from L 3to L 5 S 1 and the thickness of ligamentum flavum at L 4、5 in different positions.The results showed that the anterior-posterior widths at L 3、L 3、4 、L 4、L 4、5 and L 5 were larger in the flexion position than in the extension,and dynamic changes of the dural sac were significant or more (P<0.001,P<0.01,P<0.05).The thickness of ligamentum flavum was less under flexion than under extension,and the change was more significant (P<0.001).We realized the mechanism of traditional Chinese maneuver therapy for lumbar spinal stenosis in the flexion position was to increase the anterior-posterior widths of the dural sac of the lumbar canal stenosis and to reduce the compression of nerve roots and the dural sac in lumbar.So the clinical symptoms were relieved.
