Abstract:

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
