摘要:

文题释义:
颈椎旋提手法:是中国中医科学院望京医院朱立国教授在传统颈椎旋转手法基础上进行的继承与创新,最大的特点是将扳动手法分解为患者自行旋转定位与术者主动提扳复位,充分发挥“筋束骨”的特性,最大限度保证了操作的安全性。
有限元分析:通过泛函数变分和连续的体网格划分对工程领域问题求解的一种数学计算方法,在骨生物力学相关研究领域已广泛应用。


摘要
背景:颈椎旋提手法治疗神经根型颈椎病的临床疗效确切,安全性较好,已广泛应用于临床中,但其对各节段颈椎椎体、椎间盘的生物力学及椎间孔面积的影响尚未系统阐明。
目的:基于三维有限元分析技术开展相关研究,为旋提手法治疗神经根型颈椎病的效应机制提供数字化证据。
方法:选择1例颈背部无异常疾患的志愿者,将其颈椎旋转至生理极限体位状态下的CT影像资料作为有限元模型材料。分别通过Mimics 19.0、Geomagic Studio 2013、Hypermash 14.0及ANSYS Workbench 2020 R2软件完成对有限元模型的初步构建,基于文献完成颈椎各组织结构的弹性模量、弹性系数赋值,基于团队前期工作基础在模型上加载旋提手法的力学工况,分析颈椎旋提手法对C3-T1节段各椎体、椎间盘的力学参数及其对颈椎旋颈对侧椎间孔面积的影响。
结果与结论:①旋提手法实施时,骨性结构的应力明显高于椎间盘等软组织;②手法操作时各颈椎椎体顶部椎板处应力高,底部椎板处应力低,关节突关节处及横突处应力较低;而各椎间盘顶部髓核处应力较低,底部与椎板连接处应力较高,但椎间盘应力最高点在顶部外侧纤维环处;③另外,加载提扳力后较之加载前,C6/C7节段椎间孔投影面积明显增大;④提示旋提手法操作具有改变颈椎本身应力结构的力学特征,并能扩大患者旋颈对侧的C6/7椎间孔面积,实现治疗神经根型颈椎病的目的。

Abstract: BACKGROUND: Cervical rotation-traction manipulation is effective and safe in the treatment of cervical spondylotic radiculopathy, and has been widely used in clinical work. However, its effects on the biomechanics of cervical vertebra and intervertebral disc and the area of intervertebral foramen have not been systematically clarified.
OBJECTIVE: Based on the finite element analysis technique, a relevant research and analysis were carried out to provide digital evidence for the mechanism of effect of cervical rotation-traction manipulation in the treatment of cervical spondylotic radiculopathy.
METHODS: The CT image data of a volunteer with no neck diseases were selected as the finite element model material at its left-handed physiological limit position. The initial construction of the finite element model was completed by Mimics 19.0 software, Geomagic Studio 2013 software, Hypermash 14.0 software, and ANSYS Workbench 2020 R2 software, respectively. Based on the literature, the grid division of cervical structure and the assignment of elastic modulus and elastic coefficient were completed. Based on the previous work of the team, the mechanical effects of cervical rotation-traction manipulation were simulated on the model. Effects of cervical rotation-traction manipulation on the mechanical parameters of each vertebral body and intervertebral disc in C3-T1 segment and on the cervical lateral foramen area were analyzed.
RESULTS AND CONCLUSION: (1) During cervical rotation-traction manipulation, the stress of bone structure was significantly higher than that of soft tissue such as intervertebral disc. (2) When operating the technique, the stress at the top of each cervical vertebra was higher, the stress at the bottom was lower, and the stress at the facet joint and transverse process was lower. The stress at the top of the intervertebral disc was lower, the stress at the bottom was higher, but the highest point of the intervertebral disc stress was outside the top. (3) In addition, after loading the lifting force, the projected area of the C6/C7 
intervertebral foramen increased significantly compared with that before loading. (4) It is indicated that the cervical rotation-traction manipulation has the mechanical characteristics of changing the stress structure of the cervical spine itself, and can expand the C6/7 intervertebral cervical foramen area on the opposite side of the patient’s cervical rotation, so as to achieve the purpose of treating cervical spondylotic radiculopathy.
