Two three-dimensional models of the fourth and fifth vertebrae were developed to clarify the mechanical causes of low back pain. The lumbar structures produced allowed the simulation, by the performance of finite element analysis, of different situations not normally achievable by experimentation. The simulations yielded data on the stress distribution inside the vertebrae and the amount of deformation that takes place. Models of the vertebrae were reconstructed by transferring data points to the software package I-DEAS Master Series. The results show large stress concentrations were found in the superior and inferior facet region and on the central surfaces of the vertebral body. Higher stress concentrations were also found in the cortical shell of the vertebrae. Whilst it was observed that the can cellous core was absorbing some of the compressive loading. The study indicated that the vertebrae act similar to man-made sandwich materials, where the outer hard cortical bone has the abi
第四的和第五 vertebrae 的五- 空间模型被发展澄清低背痛的机械因素。 腰的结构生产允许模拟,藉着有限元素分析的表现,被实验不正常做得成的不同情形。 模拟在 vertebrae 和发生的毁坏数量里产生在压迫力分配上的数据。 vertebrae 的模型被藉由把数据点转移到第一软件包重建-DEAS 主人系列。 结果表示集中被在上好的和次等的方面区域中和在椎骨的身体中央表面上发现的大压迫力。 比较高的压迫力集中在 vertebrae 的外皮贝壳中也被发现。 当它被观察罐子 cellous 核心正在吸收一些有压缩力的载入时候。 研究指出了 vertebrae 表现相似到人造的三明治材料,在外部的努力外皮的骨头有抵抗压痕和磨灭的能力地方而罐子 cellous 核心是强硬的并且有能力吸收能源。与扮演许多低的背面一个中央的角色机械的载入扰乱, 即使当没有外伤的历史, 而且当退化是显然的时候。 这一项礼物研究提供一个强壮的原理给如一个研究工具的这一个模型方法的使用以许多方式协助临床医生: 藉由指出该如何避免过载针的结构,藉由协助诊断和外科技术的发展。
