摘要
本研究首先建立腰椎椎间融合三维有限元模型,旨在分析腰椎椎间融合内部生物力学响应。在此基础上进行前路单节段融合,以观察复位,融合,固定后的应力分布和临近节段退变机制。目的为脊柱内固定设计和应用提供理论依据。同时为腰椎融合,固定进行临床观察和研究,尤其为手术方法的选择和适应症提供参考。
Three dimensions finite element model of lumbar inter-body fusion was established to analyse internal biomechanical responses of lumbar inter-body. Single inter vertebrae fusion was performed and fixed with pedicle screw then we observed stresses distribution of lumbar and analysed degeneration mechanism of the neighboring inter-vertebrae joints. The study provided some information on the design and application of spinal internal fixation devices. At the same time we indroduced a model on studies of the lumbar fusion and fixation.
