| 【摘要】目的 探讨椎体位移对椎间盘内压力的影响，纠正椎体位移在手法治疗椎间盘突出症中的意义。方法 选择8只杂种犬，取L3－L5段脊柱椎体，固定在自制的器械上，将L4椎体后仰前倾，测量新鲜杂种狗腰椎椎体位移及纠正后椎间盘内压力变化。结果 当椎体后仰椎间盘后外侧压力增加明显（P＜0.01），椎体前倾时椎间盘后外侧压力减小明显（P＜0.01），而当椎体恢复原位，压力恢复原水平，两者无显著差异（P＞0.05）。结论 1.椎体位移使相邻椎间盘局部应力发生变化。椎体后仰时下方椎间盘后外侧力明显增大。2.手法治疗通过纠正椎体位移，可以确切、有效的使来自椎间盘内部的异常压力消失，解除对神经根的压迫从而达到治愈的目的。 |

| ABSTRACT Objective To study the impact of vertebral displacement on intradiscal pressure and the correct effect of vertebral displacement on manipulative treatment of vertebral disc protrusion.Methods Specimens of spinal segments L 3 L 5 from 8 hybrid dogs were fixed on self made instrument.The intervertebral disc pressure and the lumbar vertebral displacement were measured during tilting the joints to posterior side and anterior side.Results The posterior lateral pressure of vertebral disc increased significantly vertebral hypsokinesised (P<0 01) and discreased significantly vertebral anteversion (P<0 01).Restoring the vertebra to original position,it was observed that,the pressure restore to the original level and no remarkble difference was seen between them.Conclusion 1 Vertebral displacement result in the change of intradiscal pressure.The posterior lateral pressure of vertebral disc increased significantly when vertebra hypsokinesis.2 During manipulative treatment,we can get rid of abnormal intradiscal pressure effectively and release the pressure on nerve root by correcting vertebral displacement. |
