[Biomechanical study of individual brace for the correction of scoliosis].

The design method of individual brace for adolescent idiopathic scoliosis (AIS) was proposed and its correction effect was investigated. Based on the 3D CT scanned data of a scoliosis patient, an accurate finite element model, which included thorax, lumbus, sacrum and pelvis, was developed; the construction of individual scoliosis brace was based on the T-L-S-P FE model, and the correction effects of three different strap tensions were investigated. The results showed that the individual brace treatment had better correction effect than did other braces in coronal plane, and it had no inverse effect on sagittal plane. The forces generated by the strap tensions are in agreement with results of the experiment reported in literature. The research provides an available method for the design of individual brace, which could help improve the effectiveness for correction of idiopathic scoliosis.
