椎间盘部分切除对颈椎运动学影响的实验研究

本文采用三维运动学的测定方法观察了椎间盘部分切除对颈椎运动学的影响。方法为将８个杂种犬新鲜颈椎活动节段标本施加模拟颈椎活动方式时的载荷，观察和记录椎间盘切除前后的三维运动变化。实验结果表明，椎间盘对维持颈椎的稳定性具有重要作用，椎间盘部分切除可明显地改变颈椎的运动学特性，影响颈椎的稳定性。

KINEMATIC EFFECTS OF PARTIAL DISCOIDECTOMY ON THE CERVICAL SPINE:AN EXPERIMENT AL STUDY

By way of three-dimensional measuremont,the kinematics of the cervical spine after partial discoidectomy was studied on 8 specimens of functional spinal units from dogs.Each specimen was subjected to partial discoidectomy,fixed on a frame and given proper load.Records of the 3-dimensional motions,before and after partial discoidectomy were compared carefully.The data demonstrated that the partial discectomy did bring about definite ill-effect on kinematics of the cervical spine.
