摘要： 目的建立解剖结构较为精确的下颈椎三维有限元模型并验证其有效性。方法采用正常成人颈椎CT 图像建立C4-C5-C6有限元模型。在屈伸、侧弯、轴向旋转加载条件下绘制模型的力矩-位移曲线，计算曲线在实验生物力学模型所建立的力矩-位移标准差范围中所占的百分比。结果和结论建立了正常颈椎C4-C5-C6节段有限元模型，力矩-位移曲线在标准差范围中所占的百分比平均为90%。

Abstract: Objective To develop and validate an anatomic detailed finite element model of the lower cervical spine. Methods The finite element model of C4-C5-C6 was constructed using lower cervical spine (C4-C5-C6) CT images of a young healthy man. This model was validated against the standard deviation corridors of experimental data for normal, nondegenerated cervical spines tested in flexion and extension,right and left lateral bending, and right and left axial rotation under physiological loading. Percent of load range deviation was introduced to measure the deviation of the model from the standard deviation corridors of experimental data. Results and Conclusion A finite element model of young normal lower cervical spine has been developed and validated. The average percentage of load range was within 90% of standard deviation corridor.
