本研究探讨了一种新的中医推拿手法--“压-伸”手法对退行性腰椎间盘突出症和小关节脱位的疗效，并从生物力学角度对该手法进行了解释。采用自行开发的生物力学软件建立正常L1-S1腰椎三维有限元模型，该模型集成了基于脊柱CT和MRI数据的解剖结构。然后利用图形技术建立了一个退行性腰椎间盘突出和小关节脱位的有限元模型。根据实际的压伸试验，采集力学参数，设置有限元分析的边界条件。结果表明，牵张加压技术对纤维环有明显的诱导作用，使中央髓核向前靠拢，前部压力增大。研究结论：腰椎有限元建模适合于分析压伸技术对腰椎间盘生物力学的影响，为压伸技术治疗腰椎间盘突出症的发病机制提供依据。
This study investigates the effect of a new Chinese massage technique named “press-extension” on degenerative lumbar with disc herniation and facet joint dislocation, and provides a biomechanical explanation of this massage technique. Self-developed biomechanical software was used to establish a normal L1–S1 lumbar 3D FE model, which integrated the spine CT and MRI data-based anatomical structure. Then graphic technique is utilized to build a degenerative lumbar FE model with disc herniation and facet joint dislocation. According to the actual press-extension experiments, mechanic parameters are collected to set boundary condition for FE analysis. The result demonstrated that press-extension techniques bring the annuli fibrosi obvious induction effect, making the central nucleus pulposus forward close, increasing the pressure in front part. Study concludes that finite element modelling for lumbar spine is suitable for the analysis of press-extension technique impact on lumbar intervertebral disc biomechanics, to provide the basis for the disease mechanism of intervertebral disc herniation using press-extension technique.
