| 摘 要： | 目的介绍桡骨三维有限元模型的建立并探讨其相关的生物力学意义,为进一步研究和构建理想的桡骨模型提供新思路。方法选择湿桡骨标本1根行CT成像得到桡骨每层横截面图像,采用大型有限元分析软件ANSYS5.6建立桡骨三维模型,采用三维十结点四面体实体单元进行网格划分及计算。结果所构建桡骨三维模型,共划分为76089个结点、49111个单元,客观反映桡骨真实解剖形态及生物力学行为,同时与CT切片图相对比以判断其精确性。结论桡骨三维有限元模型的构建,可以为桡骨正常力学行为以及骨折后内固定的力学基础研究提供精确模型。

| Abstract: | Aim To introduce the construction of three dimensional (3D) model of radius and investigate its biomechanical significance for providing a new method for the continued research.Methods CT scanned one wet radius sample from corpse of a male adult aged 38, dying of craniocerebral trauma, and the images of every layer of cross section of radius were obtained. The radius model was constructed by means of Ansys5.6 software, divided and calculated by 3D ten nodal point and tetrahedron entity unit.Results The 3D radius model, divided into 76089 nodal points and 49111 units, objectively reflected the real radius anatomy and biomechanical behavior by contrast with radius CT image for the judgment of accuracy.Conclusion The construction of 3D radius model provides the accurate radius model for the research of normal mechanical behavior or mechanical basis of internal fixation after fracture. |
