摘要: 研究背景：脊柱侧凸是一种人体脊柱在空间上产生弯曲变形的疾病，有的侧凸还伴随着椎体旋转，且严重时会伴随多种并发症。青少年特发性脊柱侧凸(AIS)即发生在青少年身上。作为一种高级的数学近似方法，有限元分析方法(FEA)已在生物力学领域研究中取得广泛应用。目前，导致脊柱侧凸发生的具体病因目前尚未明确。目的：本研究旨在建立一例脊柱侧凸模型，利用有限元技术得出其各个节段的活动度，将其与以往研究中正常脊柱的活动度对比。方法：获取一例AIS患者的CT数据，利用Mimics，Solidworks等软件对模型进行三维重建，利用Ansys软件得到其相应的活动度数值。结果：T1-T12节段椎体(正常无侧凸)的活动度与正常脊柱的高度相似，L1-L5节段椎体(侧凸部分)的活动度与正常脊柱的存在差异。结论：脊柱侧凸会对关节活动度造成影响。
Abstract: Research Background: Scoliosis is a disease in which the human spine bends and deforms in space, and some scoliosis is accompanied by vertebral rotation, and in severe cases, it can be accompanied by various complications. Adolescent idiopathic scoliosis (AIS) occurs in adolescents. As an advanced mathematical approximation method, finite element analysis (FEA) has been widely used in the field of biomechanics research. At present, the specific causes of scoliosis are not yet clear. Objective: This study aims to establish a scoliosis model and use finite element technology to obtain the range of motion of each segment, and compare it with the range of motion of normal spine in previous studies. Method: Obtain CT data of an AIS patient, use Mimics, Solidworks and other software to perform 3D reconstruction of the model, and use Ansys software to obtain its corresponding activity values. Result: The range of motion of the T1-T12 vertebral bodies (normal without scoliosis) is similar to the height of the normal spine, while the range of motion of the L1-L5 vertebral bodies (scoliosis) is different from that of the normal spine. Conclusion: Scoliosis can affect joint mobility.
