旋转对实验性颈椎间盘突出影响的研究

Study on the Effect of Rotation on Experimental Protrusion of Cervical Intervertebral Disc

目的采用几种常用的旋转手法观察对实验性颈椎间盘突出的影响。方法将制成颈椎间盘突出模型的尸体标本固定在生物材料实验机（ＭａｔｅｒｉａｌＴｅｓｔＳｙｓｔｅｍ）上，在不同牵引重量和旋转角度作用的同时，观察突出髓核的变化情况。结果在各种实验状态下旋转颈椎标本时，突出的髓核均无明显地增大。结论适度的旋转手法对无明显退变的患者是比较安全的。

Objective To observe the effect of several commonly used rotatory manipulations on experimental protrusion of cervical intervertebral disc.Methods Cervical spines,taken from cadavers,were made protrusion of intervertebral disc experimentally.And then the preparations were fixed on material test system to observe the changes of the protruded nucleus pulposus under traction and rotation in different states.Results There was no obvious enlargement of the protruded nucleus pulposus under various kinds of test condition.Conclusion The moderate rotatory manipulation is relatively safe for the patient without obviously retrograde degeneration.
