The objective of this study was to construct a three-dimensional (3D) finite element model of the hip. The images of the hip were obtained from Chinese visible human dataset. The hip model includes acetabular bone, cartilage, labrum, and bone. The cartilage of femoral head was constructed using the AutoCAD and Solidworks software. The hip model was imported into ABAQUS analysis system. The contact surface of the hip joint was meshed. To verify the model, the single leg peak force was loaded, and contact area of the cartilage and labrum of the hip and pressure distribution in these structures were observed. The constructed 3D hip model reflected the real hip anatomy. Further, this model reflected biomechanical behavior similar to previous studies. In conclusion, this 3D finite element hip model avoids the disadvantages of other construction methods, such as imprecision of cartilage construction and the absence of labrum. Further, it provides basic data critical for accurately modeling normal and abnormal loads, and the effects of abnormal loads on the hip.
本研究旨在构建髋关节的三维（3D）有限元模型。髋关节的图像来自中国可视人体数据集。该髋关节模型包括髋臼骨、软骨、盂唇和骨。使用 AutoCAD 和 Solidworks 软件构建股骨头软骨。将髋关节模型导入 ABAQUS 分析系统。对髋关节关节的接触面进行网格划分。为了验证模型，对单腿峰值力进行加载，观察髋关节软骨和盂唇的接触面积以及这些结构中的压力分布。构建的 3D 髋关节模型反映了真实的髋关节解剖结构。此外，该模型反映了类似于先前研究的生物力学行为。总之，这种 3D 有限元髋关节模型避免了其他构建方法的缺点，如软骨构建不准确和盂唇缺失。此外，它为准确模拟正常和异常载荷以及异常载荷对髋关节的影响提供了关键的基础数据。
