Abstract

Objective: To establish a 3D finite element model of human hip joint and verify its validity, to be used for subsequent biomechanical analysis. Method: The hip joint in one healthy adult male volunteer was scanned by CT. The 3D finite element model of the hip joint was constructed with Mimics and Ansys software. The simulated weight pressure of hip upright position was applied to this model, the stress distribution was compared with the related literature. Result: The 3D finite element model of human hip joint was established successfully, including 284 183 points of 160 665 units. Under the action of simulated gravity, the stress distribution was in agreement with previous experimental results. Conclusion: The established 3D finite element model had good simulation and could be used in the clinical biomechanics analysis.
