Biomechanical Study Of The Scoliotic Adolescent Spine

Scoliosis is a complex three-dimensional deformity of the spine and rib cage that produces cosmetic asymmetries of the trunk. The AIS(adolescent idiopathic scoliosis) accounts for the maximal proportion of cases of scoliosis, which damage the health of adolescent seriously. Experts from medical field and industry field pay much attention to the research of the mechanism and correction patterns of scoliosis.This paper is based on the key project"mechanical virtual human of China"supported by National Natural Science Foundation, and project"Biomechanical study of adolescent idiopathic scoliosis"funded by the Public health bureau of Shanghai. The 3D geometrical model and mechanical model of spine system were built to analyse the biomechanical characteristic of scoliotic spine, which provide a platform for the numerical analysis of scoliosis correction patterns. This platform support the theoretical research of correction brace and also build a connection between doctor and patient.Based on computed tomography scan and CAD&FEA technologies, contour lines of centrum was obtained and Finite element model of...
