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.
