【摘要】 研究青少年特发性脊柱侧凸患者个性化支具的设计方法及其矫形效果。首先通过一例脊柱侧凸患者的三维CT数据,建立胸腰骶及骨盆的有限元模型,在该模型基础上研究个性化支具的设计并根据临床实际情况对其矫形效果进行仿真。结果表明,个性化支具在冠状面内的矫形效果好于其它支具并且在矢状面内没有副作用,由束紧力引起的支具上的作用力与文献实验结果基本一致。本研究为个性化支具的设计提供了一种切实有效地方法,可以提高患者的矫形效果。更多还原

【Abstract】 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.更多还原
