摘要:

文题释义:
腰椎间盘突出症:是指因腰椎间盘变性、纤维环破裂和髓核组织突出刺激或压迫相应节段脊神经根或马尾神经,从而产生腰部疼痛、一侧或双侧下肢麻痛及神经功能损害的一系列临床症状和体征,是腰腿痛常见的原因之一。
有限元分析法:是将一个物体或系统分解为由多个相互联结的、简单、独立的点组成的几何模型,在此模型上应用线性代数的方法求解复杂问题。

背景:南少林手法将武术精华运用于整骨理筋和按摩手法中,形成了独特的中国骨伤治疗技术,研究发现南少林理筋整脊手法治疗腰椎间盘突出症有显著疗效。
目的:运用三维有限元法分析倒盖金被手法作用于腰椎间盘的生物力学效应。
方法:选择一名健康青年男性志愿者,根据其CT扫描结果构建全腰椎(L1-L5)三维有限元模型。在已验证有效性的全腰椎模型上模拟加载倒盖金被手法,计算不同顶推高度下腰椎间盘的应力分布及变化情况。
结果与结论:①当L3椎体被顶推10 cm总位移后,各椎间盘平均应力最值约9.2 MPa,其中L4-5椎间盘存在部分单元的应力集中现象。②随着顶推高度的增加,各椎间盘的应力呈现近似线性增长的趋势,各椎间盘应力值范围分别为:L1-2椎间盘1.36-7.36 MPa,L2-3椎间盘1.64-7.82 MPa,L3-4椎间盘1.52-9.20 MPa,L4-5椎间盘1.25-8.71 MPa;应力分布情况为:L3-4 > L4-5 > L2-3 > L1-2。③腰椎间盘应力变化以髓核为中心向边缘递增,应力最大处为纤维环前侧。④结果表明,倒盖金被手法操作时腰椎间盘总体应力分布规律前后一致、逐渐递增,提示手法操作应循序渐进,以确保其安全性。

Abstract: BACKGROUND: The South Shaolin technique uses the essence of martial arts in bone and tendon and massage techniques to form a unique Chinese bone injury treatment technique. Research has found that the South Shaolin tendon and chiropractic technique has a significant effect on the treatment of lumbar disc herniation.  
OBJECTIVE: To analyze the biomechanical effects of Daogaijinbei manipulation on the lumbar intervertebral disc by using the three-dimensional finite element method.
METHODS:  A healthy young male volunteer was selected to construct a three-dimensional finite element model of the lumbar spine (L1-L5) based on the CT scan results. The stress distribution and variation of lumbar intervertebral disc under different jacking heights were calculated by simulating loading Daogaijinbei manipulation on the validated lumbar spine model.  
RESULTS AND CONCLUSION: (1) The maximum average stress of each lumbar intervertebral disc was about 9.2 MPa after being pushed by a total displacement of 10 cm in L3, and there was stress concentration in some units of the L4-5 intervertebral disc. (2) With the increase of the jacking height, the stress of each intervertebral disc presented an approximate linear growth trend. The stress values of each intervertebral disc were: 1.36-7.36 MPa in L1-2 intervertebral disc, 1.64-7.82 MPa in L2-3 intervertebral disc, 1.52-9.20 MPa in L3-4 intervertebral disc, and 1.25-8.71 MPa in L4-5 intervertebral disc. The stress distribution was: L3-4 > L4-5 > L2-3 > L1-2. (3) The stress variation of lumbar intervertebral disc increased from nucleus pulposus to the edge, and the maximum stress was in the anterior side of annulus fibrosus. (4) During Daogaijinbei manipulation, the overall stress distribution of the lumbar intervertebral disc is consistent and gradually increasing, which suggests that manipulation should be done little by little to ensure patients’ safety.
