Design Of Individual Brace For The Three-Dimensional Correction And Biomechanical Study

Cobb angle at below 40° the patients with mild to moderate, brace treatment is currently the only effective non-surgical forms of treatment. Existing brace treatment for the correction of the effects are mainly concentrated on the spine of Coronal, sagittal and transverse synchronous rectification is not obvious, that cannot realize the correction and there is poor compliance, and could easily lead to flat back, personalization and other problems that affect the treatment of the effect cannot be achieved. Therefore, the pathogenesis of IS and orthopaedic programmes of study is of great practical significance.The research is proposed in this context, aiming at with design of individual brace for the three-dimensional correction as the object of the research. Establish three-dimensional geometry model based on CT data with AIS patient, and then construct a completely finite element model based on the human anatomy. On the basis in validation model effectiveness research on rapid design method of individual brace, graphical grid command is used to obtain cross-sectional contour curve with patient, further generating brace surfaces, through reasonable set gasket distribution, follow deformity spine curve simulation clinical spine by force, analysis different orthopedic force and the role location on orthopedic effects, and according to clinical actual for support with orthopedic effect of biomechanical analysis, so as to determine the optimal design. For the design of individual brace provides a practical approach, improving the effect of brace correction, has good meaning and application prospect.
