目的：应用颈椎三维有限元模型，探讨颈椎“椎骨错缝”对颈椎病患者关节和椎间盘应力的影响。
方法：选取颈椎病患者，通过颈椎动静态触诊和X线判定发生“椎骨错缝”的患者1例(男，28岁),CT扫描C1-C7(层厚0.75 mm), 基于CT数据，应用特定三维有限元分析软件对椎骨错缝节段(C4-C6)进行三维有限元模型创建，基于本模型应用软件模拟临床手法矫正“错缝椎骨”C5,然后应用有限元分析软件计算和分析这一形变过程关节突关节和椎间盘的应力变化。
结果：错缝节段C5对相邻节段C4,5、C5,6的椎间盘和关节突关节的应力均发生改变，且C5,6椎间盘和关节突关节的应力均明显大于C4,5椎间盘和关节突关节受到的应力。
结论：“椎骨错缝”后易引起相应关节突关节和椎间盘的异常应力，而手法矫正“椎骨错缝”能有效改善异常应力分布。 |

Abstract:
Objective: To study the effect of vertebrae semi-dislocation on the stress distribution in facet joint and interuertebral disc of patients with cervical syndrome using three dimensional finite element model.
Methods: A patient with cervical spondylosis was randomly chosen,who was male,28 years old,and diagnosed as cervical vertebra semidislocation by dynamic and static palpation and X-ray,and scaned from C1 to C7 by 0.75 mm slice thickness of CT. Based on the CT data,the software was used to construct the three dimensional finite element model of cervical vertebra semidislocation(C4-C6). Based on the model,virtual manipulation was used to correct the vertebra semidislocation by the software,and the stress distribution was analyzed.
Results: The result of finite element analysis showed that the stress distribution of C5-6 facet joint and intervertebral disc changed after virtual manipulation.
Conclusion: The vertebra semidislocation leads to the abnormal stress distribution of facet joint and intervertebral disc. |
