Research of the motion compensation after single segmental cervical spine fusion surgery

Abstract

Objective To know the motion compensation regulation of each segments after single segmental cervical spine fusion surgery.Methods With the help of 3D motion information collecting system,the movement angle of each segment was recorded before and after single segmental cervical spine fusion surgery.Results All the statistics are dealed with normalization,we got the statistics of the motion compensation regulation of each segments after single segmental cervical spine fusion surgery,range of motion of each segment increased diversely,especially the lower adjacent segment,with statistical significance(P＜0.05).Conclusion Compensatory enhancement of the range of motion of adjacent segments is one of the important reasons lead to the degeneration.
