摘要: 基于有限元方法,研究比较了4种不同入路方法的腰椎椎体间融合方法(ALIF,PLIF,TLIF和DLIF)对全身振动状态下的腰椎融合节段及邻近节段的影响.引入了与并发症相关的重要指标,如应力分布、应力峰值及应力振幅等,并进行了比较分析.结果表明:在4种不同的方法中,ALIF可以为全身振动状态下的相邻节段提供一个更稳定的环境,并且该方法具有较好的抗振性能.与其他方法相比,DLIF可以降低振动状态下椎间融合器下沉及失效的风险.而且,DLIF可以为全身振动状态下的椎骨细胞提供一个更稳定、更合适的生长环境,更有利于椎骨融合成功.

Abstract: Based on the finite element method, the effects of four different methods of lumbar interbody fusion (ALIF, PLIF, TLIF and DLIF) on the lumbar fusion segments and adjacent segments under the condition of whole-body vibration were compared. Some important indexes related to complications such as stress distribution, stress peak and stress amplitude were introduced and compared. The results showed that ALIF can provide a more stable environment for the adjacent segments in the whole-body vibration state among the four different methods, and this method has better anti-vibration performance. Compared with the other methods, DLIF can reduce the risk of cage subsidence and failure. Besides, DLIF can provide a more stable and suitable environment for the growth of vertebral cells in the state of whole-body vibration, which is more conducive to the success of vertebral fusion.

Key words: anterior lumbar interbody fusion(ALIF); posterior lumbar interbody fusion(PLIF); trans-foraminal lumbar interbody fusion(TLIF); direct lateral lumbar interbody fusion(DLIF); whole-body vibration
