摘要:
应用有限元技术模拟直腰旋转手法治疗腰椎间盘突出症,分析两种不同加载求解方式下腰椎间盘位移与应力结果。方法:利用正常青年志愿者腰骶部CT数据,使用Mimics,Geomagic Studio,Ansys等软件建立L4～5正常三维有限元模型,假定腰椎间盘突出症发生于椎间盘左后方,模拟右向直腰旋转手法,分别应用传统一步加载求解与笔者提出的二步加载分步求解方式计算L4～5椎间盘左后方节点的应力与位移,对两种求解方式所得结果进行统计学比较。结果:一步加载求解L4～5椎间盘左后方位移为(-1.264 0±0.171 5)mm,应力为(0.032 5±0.032 4)MPa; 二步加载分步求解所得位移为(-1.566 0±0.169 5)mm,应力为(-0.004 5±0.030 4)MPa.两种加载求解所得L4～5左后方节点位移与应力比较,差异均有统计学意义(P<0.05)。结论:二步加载分步求解方式用于手法治疗腰椎间盘突出症有限元研究,其计算结果更准确地反映了手法作用对腰椎间盘的力学影响。
Abstract:
To simulate lumbar erection-rotation manipulation for treating lumbar disc herniation using finite element technique and analyze the displacement and stress in lumbar intervertebral disc under two different loading and solving methods. Methods: A normal three-dimensional finite element model of L4～5 was established using software's of Mimics, Geomagic Studio, and Ansys based on the lumbosacral CT data of a normal young volunteer. Lumbar disc herniation was assumed to occur in the left rear of the intervertebral disc, and then lumbar erection-rotation manipulation was simulated rightward, and traditional one-step loading and solving method and two-step loading and solving method were used to calculate the stress and displacement of the nodes in the left rear of L4～5 intervertebral disc, respectively. A statistical comparison was carried out to evaluate the results of two methods. Results: Based on the one-step loading and solving method, the displacement in the left rear of L4～5 intervertebral disc was(-1.264 0±0.171 5)mm, the stress value was(0.032 5±0.032 4)MPa, and based on the two-step loading and solving method, the displacement was(-1.566 0±0.169 5)mm, the stress value was(-0.004 5 ± 0.030 4)MPa. There were significant differences in displacement(P<0.05)and stress(P<0.05)between the two loading and solving methods. Conclusion: In finite element study on lumbar disc herniation treated using Chinese manipulation, the calculation results of two-step loading and solving method were more accurate in revealing the mechanical effect of manipulation on lumbar intervertebral disc.
