VIRTUAL HUMAN HIP JOINT OBTAINED FROM CT IMAGES AND FEM TEST
Keywords:Virtual hip, normal walking loads, pubic symphysis, virtual test, bone models
Hip joint is one of the most complicated in the human body. It is complex due to the complicated geometry, but also to the biomechanics of this joint. Initially, three-dimensional scanning of a femur was attempted, but due to the fact that only the outer geometry could be obtained, this method was dropped. Computational methods have been used that based on identifying shades of gray on tomographic images and transposing them into geometries (surfaces). These surfaces processed with the Geomagic program were transformed into virtual solids in SolidWorks. In this program, bone components were assembled and pubic symphysis was modeled. Finally, the model was exported to Ansys where, based on normal walking loads, a finite element method simulation was performed. At the end of the paper interesting conclusions were highlighted.
