摘要:


文题释义:

斜扳手法:患者取侧卧位,患侧在上,患侧下肢呈屈髋屈膝体位,并且使健侧下肢保持伸直,术者正对患者,一手掌按住其肩前部,另一手用肘部(或手掌)抵住其臀部,然后双手协同用力,作相反方向上的缓慢推动,使其腰椎被动扭动,当旋转到最大限度时,再做一个稍增大幅度的突发性扳动,一般此时可听到“喀嗒”的弹响声,表示手法成功。
有限元分析:利用数学近似的方法对真实物理系统进行模拟。将复杂问题分解为简单而又相互作用的因素,就可以用有限数量的未知量去逼近无限未知量的真实系统。

背景:斜扳手法对于腰椎关节滑膜嵌顿的疗效可靠,已被临床广泛应用,但是斜扳手法治疗腰椎关节滑膜嵌顿的相关研究还比较欠缺。
目的:利用三维有限元法分析斜扳手法治疗腰椎关节滑膜嵌顿的生物力学作用机制,为斜扳手法治疗腰椎关节滑膜嵌顿提供理论依据。
方法:采集腰椎关节滑膜嵌顿患者的腰椎CT数据,利用Mimics和Ansys软件建立脊柱L4-5运动单元的三维有限元模型。模拟临床左侧卧位斜扳手法的操作过程,分析斜扳手法对腰椎L4-5节段各组织结构生物力学、形态变化以及小关节接触面积的影响。
结果与结论:①建立了腰椎L4-5节段三维有限元模型,并验证了模型的有效性;②在施加斜扳手法前后,左侧小关节软骨应力从2.959 MPa增加到14.35 MPa,应变从0.078 34增加到0.345 1,关节软骨接触面积从20.806 2 mm2增加到94.872 7 mm2;而右侧小关节软骨应力从3.127 MPa
减小到0 MPa,应变从0.081 96减小到0,关节软骨接触面从16.705 3 mm2减小到右侧0 mm2;③提示斜扳手法对于腰椎滑膜嵌顿患者具有良好的疗效,其可以改变关节突关节的应力、应变、上下关节突的接触面积,充分松解、打开关节突关节,达到复位关节突关节、解除滑膜嵌顿的治疗目的。

Abstract: BACKGROUND: Oblique-pulling manipulation has a reliable curative effect on lumbar synovial incarceration, and it has been widely used in the clinic. However, the related research on the treatment of lumbar synovial incarceration by oblique-pulling manipulation is still relatively lacking.  
OBJECTIVE: To analyze the biomechanical mechanism and effect of oblique-pulling manipulation in the treatment of lumbar synovial incarceration by three-dimensional finite element method, and provide theoretical basis for the treatment of lumbar synovial incarceration by oblique-pulling manipulation.
METHODS: The CT data of patients with lumbar synovial incarceration were collected, and the three-dimensional finite element model of L4-5 motor unit of spine was established by using Mimics and Ansys software. The operation process of the oblique-pulling manipulation in the left lateral position was simulated, and the influence of the oblique-pulling manipulation on the biomechanics, morphological changes and facet joint contact area of each tissue structure of L4-5 segment of lumbar spine was analyzed.  
RESULTS AND CONCLUSION: (1) A three-dimensional finite element model of lumbar L4-5 segment was established, and the validity of the model was verified. (2) Before and after the oblique-pulling manipulation was applied, the stress of left facet joint cartilage increased from 2.959 MPa to 14.35 MPa; the strain increased from 0.078 34 to 0.345 1, and the contact area of articular cartilage increased from 20.806 2 mm2 to 94.872 7 mm2. On the other hand, the stress of the right facet joint cartilage decreased from 3.127 MPa to 0 MPa; the strain decreased from 0.081 96 to 0, and the articular cartilage contact surface decreased from 16.705 3 mm2 to 0 mm2 on the right. (3) It is concluded that oblique-pulling manipulation has a good effect on patients with lumbar synovial incarceration. It can change the stress and strain of the articular process and the contact area of the upper and lower articular processes, fully release and open the articular process, and achieve the therapeutic purpose of reducing the articular process and relieving the synovial incarceration.
