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。

Single segmental spinal interbody fusion with bisegment fixation for thoracolumbar burst fracture type B had a good immediate stability in flexion, extension, lateral bending motion.
