摘要:

文题释义:
蒙医整骨术: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。

背景:目前中国蒙医整骨术以手法繁复、理论驳杂著称,结合尺桡骨骨折有限元断裂模型专门进行力学原理分析的阐述,国内外未见相关报道。

目的: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,并分析蒙医整骨对应骨折的手法机制。

方法:选择1名35岁男性志愿者,签署知情同意书后获取右臂前肢CT影像资料,建立尺桡骨几何模型,依据骨组织技术指标设定材料参数,划分网格,赋予载荷参数,进行分析运算。以Colles骨折与Smith骨折常见损伤原因为判断依据,结合蒙医整骨“以力对力”原则进行整骨手法判断。

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,在对应力方向获得了伸直性、屈曲性骨折的力学模型,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,能够较好的模拟尺桡骨骨折断裂情况,从而为蒙医整骨“以力对力”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 model of ulna-radius fractures, the analysis on the manipulation of osteopathy has not been reported at home and abroad.

OBJECTIVE: To simulate the force of various ulna-radius fractures and establish the model of ulna-radius fractures, to analyze the effect, and to analyze the manipulation mechanism of Mongolian osteopathy on the corresponding fractures.

METHODS: One 35-year-old volunteer was selected to obtain the CT image data of the right forelimb after signed the informed consent. The geometric model of the radius and ulna was established based on the parameters of bone tissue. The material mesh was divided, and the load parameters were assigned for analysis and calculation. Based on the common causes of Colles and Smith fractures, the osteopathy manipulation was evaluated by combined with “force to force” of Mongolian osteopathy.

RESULTS AND CONCLUSION: (1) The stress distribution of the model of ulna-radius fractures is highly consistent with previous studies of the forearm. The mechanical models of Colles and Smith fractures were obtained in the direction of stress. After adjusting the mechanical parameters of bone, the fracture models of four different ages could be simulated. (2) These results indicate that the finite fracture model is feasible. Meta-analysis could simulate the ulna-radius fractures, and provide a manual reference for treating ulna-radius fractures with “force-to-force” theory in Mongolian osteopathy.

Key words: Mongolian osteopathy, ulna and radius, fracture, finite element analysis, stress
