摘要： 本文综述了颈椎融合术后在体运动学研究进展。通过查阅颈椎融合术后有关在体运动学的相关文献，从融合相邻节段椎体间运动范围的改变、剩余运动节段在颈椎整体活动度中所占比重变化规律、融合相邻节段小关节运动模式以及相邻节段旋转中心的位置偏移等方面进行归纳总结。以期望能发现融合术后相邻椎体退变的早期征兆，为临床上相邻节段病理改变（adjacent segment pathology，ASP）的治疗提供理论依据。目前相关运动学研究多局限于对颈椎矢状面屈伸活动的观察，鲜有三维空间内的六个自由度（6-degree-of-freedom，6DOF）运动数据报道。而且，相关运动学研究并没有终止争论，ASP是由过度运动引起，还是颈椎病病程自然发展的结果仍存在争议。长期随访的大样本随机对照研究，获得精确的6-DOF运动学参数或许是解决争议的最佳途径。

Abstract: To review the researches of in-vivo kinematics after cervical arthrodesis. Related literature concerning the kinematics in patients after cervical arthrodesis was extensively reviewed and comprehensively analyzed in 4 terms of changes in adjacent segment range of motion , motion segment percent contributions, motion pattern of cervical facet joints, and deviated center of rotation at adjacent segments. These reported researches of in-vivo kinematics after cervical arthrodesis was almost on the sagittal plane. Few data have been reported on the 6-DOF kinematics under physiological loading conditions. Whether adjacent segment pathology caused by hypermobility remains controversial. Long-term follow-up of large sample randomized controlled studies and obtaining the accurate 6-DOF kinematics are the best way to resolve controversy.
