A three-dimension FEM model of normal L4-5 was built, and the lumbar facet joints were treated as to contact with each other. Various motions of L4-5 were simulated by changing the loads: anteflexion, retroversion, right rotation, right bending and longitudinal compression.
本文建立了L4-5正常运动节段的有限元模型,将两小关节面处理为接触模型,分析了小关节面在腰椎前屈、后伸、侧弯、旋转及压缩运动状态下的受力情况,发现小关节在承载方面作用较大,特别是抗旋转运动过程中作用更明显。
