摘　　要：目的寻求髋臼三维有限元模型构建的方法并探讨记忆生物力学的临床意义。方法选择成年湿髋臼尸体标本行CT扫描成像得到髋臼每层横截面图像,提取边界坐标,利用有限元分析软件ANSYS5.6构建髋臼三维有限元,三维十结点四面体实体单元进行网格划分。结果所构建髋臼模型共划分为121239个结点、112491个单元,客观反映髋臼真实解剖形态及生物力学行为。结论构建的髋臼三维有限元模型,为髋臼骨折内固定的记忆力学研究提供可循模型。AIM:To seek the method to construct three dimensional (3D) acetabular model and to explore the clinical significance of memory biomechanics.METHODS:One wet acetabular sample from adult corpse was scaned by CT scan and all images of every cross section acetabular layer were obtained. The 3D acetabular model was constructed with the ANSYS 5.6 software.RESULTS:The constructed 3D acetabular model clearly reflected the real acetabulum anatomy and biomechanical behavior,and it was divided into 121 239 nodes and 112 491 units. CONCLUSION:The construction of 3D acetabular model can provide true acetabular model for the research on memory biomechanics of internal fixation after fracture.
