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.
