摘要
应用三维有限元方法对腰椎椎体应力分布的研究表明.椎体松质骨的应力集中区域位于邻近终板的中央部分,而椎间盘发生退变后这一现象即不明显.作者认为椎体的应力分布及腰椎的载荷传递依据椎间盘的情况而不同,并对有关的临床意义进行了讨论.
The biomechanical study of vert-ebral bodies in lumbar spine with three—dimensional finite element methodshowed that the region of stress con-centration was located in the centralpart of the bodies,adjacent to thenucleus pulposus,but following thedegeneration of the intervertebral disc, the stress concentration became notsignificant.The authors believe thatstress distribution and load transmi-ssion in vertebral bodies of lumba-spine depend on the condition ofintervertebral disc.The clinical re-levance is discussed.
