摘要
目的探讨颈椎双节段融合术后上、下相邻及非相邻节段的运动补偿规律。方法通过三维运动采集系统捕捉到6具新鲜人尸体颈椎双节段融合术前、后C2-T1各节段在前屈、后伸、左侧屈、右侧屈、左旋转、右旋转6种状态下的运动角度数据，并将结果进行分析。结果经过归一化处理后，分析得出颈椎双节段融合术后各节段的运动变化规律，发现融合术后其他各节段六种运动状态下运动幅度均有不同程度的增加，尤其是下相邻节段，差异均有统计学意义（P〈0．05）。其中后伸、前屈及双向侧屈融合效果更好，稍优于左旋及右旋状态下的融合效果。而在运动补偿比例这点，各运动状态，下相邻节段的运动补偿比例（平均值大于30％）也远高于其它节段。结论颈椎双节段融合术后邻近节段的代偿性运动幅度增加是导致其退变的重要原因。
Objective To investigate the mechanics of adjacent degeneration segments and the motion compensation regulation after double segmental cervical spine fusion surgery. Method With the help of 3D motion information collecting system, the movement angle of each segment was recorded before and after double segmental cervical spine fusion surgery under the condition of flexion, extensional left bending, right bending, left rotation, right rotation. Result All statistics are dealt with normalization, we got the statistics of the motion compensation regulation of each segments after double segmental cervical spine fusion surgery, range of motion of each segment increased diversely under each condition, especially the lower adjacent segment（P〈0.05）. It fused better than other conditions under the condition of flexion, extension, left and right bending. The motion compensation ratio of the lower adjacent segment was greater than others （the average~〉30%） under each condition. Conclusions Compensatory enhancement of the range of motion of adjacent segments is one of the important reasons lead to the degeneration
