Objective To analyze the value of using setover of the cervical spinous process to assess cervical vertebral semidislocation and sinew out-of-trough. Methods 62 cases of multi-slice spiral pictures of cervical spondylosis patients were chosen randomly and measured the angle of cervical vertebra rotation and spinous process setover. Results The angle of upper cervical vertebral revolution was greater than the lower, and more patients were rotated left. The rate of the cervical vertebra rotation was decreasing gradually from C2 to C7 ;There was an mcreasing trend of the spinous process setover from C2 to C7. There were no statistically significant differences among each spinous process. As for single vertebra. there was a significant difference between the angle of vertebral rotation and the angle of spinous process setove in C6and C7. Conclusion It is of great importance to apply the CT imaging to evaluate the cervical vertebral semidislocation and sinew out-of-trough.%目的 根据影像学资料客观分析颈椎棘突偏歪评估颈椎"骨错缝、筋出槽"的临床价值.方法 随机抽取62例门诊颈椎病患者的多层螺旋CT影像,应用影像归档和通信系统(picture archiving and conmunication systems,PACS)软件进行椎体旋转及棘突偏歪的测量.结果 颈椎上颈段椎体旋转角度明显大于下颈段椎体旋转角度,且以左旋者较多;颈椎椎体的旋转发生率自C2至C7逐渐减小;颈椎棘突偏歪率自C2至C7呈现逐渐增大的趋势,各棘突偏歪角度之间没有显著差异;就单个椎体而言,C6、C7椎体旋转角度和棘突偏歪角度之间差异有显著性.结论 触诊或X线平片发现的颈椎棘突偏歪,需要结合CT等影像学资料,才能更为客观准确地评估颈椎"骨错缝、筋出槽".
