| 摘 要： | 【目的】采用生物力学的方法分析模拟推拿时正常和退变腰椎小关节的应力分布状况。【方法】通过有限元及配套影像方法，建立能准确反映第4腰椎与第5腰椎间(L4-5)小关节实际状况的有限元模型，对模型分别施加前屈、后伸、侧弯、旋转与压缩5种载荷，以分析比较其在模拟推拿作用时的受力情况。【结果】腰椎小关节在承载方面具有较大的作用，特别是在抗旋转推拿运动过程中的作用更为明显。【结论】对有明显退变的腰椎，使用前屈旋转手法时以轻巧手法为宜。 |

| Abstract: | Objective] To analyze the stress distribution in facet joint of lumbar spine on normal and degenerative models with biomechanical method during the manipulation. Methods] The finite element model of lumbar facet joint of L4-5 were reconstructed with finite element method and imaging method. Different movements such as anteflexion, retroflexion, lateral flexion, rotation and compression were loaded on the models and then stress distribution during the mimetic spinal manipulation was analyzed and compared. Results] The facet joint of lumbar spine has an important role in resisting load, especially in resisting rotation. Conclusion ] The strong flexion-rotation manipulation should be avoided for seriously degenerative subject. |
