文题释义:
蒙医整骨:是蒙古族历代医者们所积累的、具有蒙古民族特色的治疗骨折与脱臼、软组织损伤等一系列整骨疗法的总称。蒙医整骨方法简练、手法简单,具有可靠的临床效果。蒙医整骨讲究“机触于处,巧生于内,手随心转,法从手出”。实施疗法的时候,需要重视人体生理功能之内在作用,注意保护人体骨骼之完整性,最大限度地发挥组织器官的自愈能力,使伤折部位及早愈合,恢复正常生理功能。
尺桡骨三维模型建立:当前科研活动当中主要使用直接建模、坐标点建模、组织切片建模,基于医学图像建模和DICOM数据直接建模。其中基于CT数据的DICOM数据建模方法因为数据来源准确而且建模过程不需要人为干预,成为有限元分析过程中最常用的建模方法。
 
摘要
背景:目前中国蒙医整骨以手法繁复,理论驳杂著称。结合尺桡骨骨折有限元断裂模型专门进行的整骨手法分析,国内外虽见相关报道,但是没有在力学角度上对蒙医整骨手法进行过论证及阐述。
目的:运用MimicsResearch及ABAQUS模拟尺桡骨各类骨折受力情况,建立尺桡骨骨折断裂模型,评估模型效果,分析蒙医整骨对应骨折的手法机制。
方法:获得1例35岁患者的正常右臂前肢CT影像资料,导入Mimics 17.0建立尺桡骨几何模型,经3-Matic Studio前期处理后,经ABAQUS 6.14设定材料参数,划分网格,赋予载荷参数,进行分析运算。
结果与结论:①尺桡骨的骨折模型应力分布情况与以往对前臂的研究高度符合,在对应力方向获得直接暴力、间接暴力及扭转暴力的力学模型,调整骨质力学参数后成功模拟出4种年龄段的不同骨折模型;②结果证明,基于Mimics和ABAQUS的有限元分析能够较好的模拟尺桡骨骨折断裂情况,应力载荷方向在确定蒙医整骨手法中起重要作用,这可为蒙医整骨治疗尺桡骨骨折提供手法参考。

Abstract:

BACKGROUND: Mongolian osteopathy is famous for the complicated manipulation and theoretical complexity. Combined with the finite element fracture model of ulnar and radial fractures, relevant reports have been illustrated, but there is a lack of study on Mongolian medical osteopathic manipulation in terms of mechanical characteristics.

OBJECTIVE: To simulate the force of various fractures of ulna and radius using Mimics Research and ABAQUS, to establish the model of ulnar and radial fractures, and to evaluate the effect and analyze the manipulation mechanism of the corresponding fractures.
METHODS: A 35-year-old volunteer was selected to obtain the CT image data of the right forelimb. The data were imported into Mimics 17.0 software to establish the geometric model of the radius and ulna. After pre-processing by 3-Matic Studio, the material parameters were set up by ABAQUS 6.14 software; the mesh was divided, and the load parameters were assigned for analysis and calculation.
RESULTS AND CONCLUSION: (1) The stress distribution of the fracture model of the ulna and radius was highly consistent with previous studies of the forearm. The mechanical models of direct, indirect and torsional violence were obtained in the direction of stress. After adjusting the mechanical parameters of bone, the fracture models of different ages could be simulated. (2) These results indicate that the finite element model based on Mimics and ABAQUS is feasible, which can simulate the fracture of ulna and radius, and the direction of stress load plays an important role in determining the manipulation of Mongolian osteopathy. The above conclusions can provide a manual reference for the treatment of fractures of ulna and radius with Mongolian osteopathy.
