Abstract:

BACKGROUND: Current hip three-dimensional finite element model is established based on human corpse data or CAD reconstruction, but the effect is not satisfactory.
OBJECTIVE: To establish three-dimensional finite element model of surface hip arthroplasty using 64-slice spiral CT scanning data to provide a standard mathematical model for further biomechanical study.
METHODS: An adult male volunteer who underwent surface hip arthroplasty was selected with no disease in the intact hip confirmed by X-ray. CT data of surface hip arthroplasty were imported into Mimics software. Three-dimensional model was established by threshold method and converted to volumetric mesh in the Abaqus software. So the three-dimensional finite element model of surface hip arthroplasty was established.
RESULTS AND CONCLUSION: The three-dimensional geometry and finite element model of surface hip arthroplasty was established. The model included 165 886 hexahedron elements and 213 343 nodes. The three-dimensional geometry and finite element model can be constructed from slice section images with Mimics and Abaqus software. The model has a high degree of morphological and mechanical simulation.
