Numerical simulations and 3D modeling of a human hip joint using finite element method

The aim of our work is to describe how to create 3D model of a healthy human hip joint directly from CT (computed tomography) or MRI images (magnetic resonance imaging). At the beginning a brief overview of orthopaedic engineering and its importance for development of medicine and personalized future medicine is given. In second part of the paper procedure of making hip joint geometry of a human hip joint (3D) and how to preform FEM analysis is presented. The three-dimensional finite element model has been performed based on patient- specific MRI images of the human hip bone with software Mimics Materialize, then for the purposes of numerical simulations 3D model was transferred to Abaqus software. A high resolution continuum tetrahedral mesh has been generated. Study was carried out on the 3D bone model with material properties, boundary conditions and movements just like in a human hip joint. The distribution map of the axial and global movements on the global model and the distribution map of the axial and von Misses strain in the surface of the hip are presented. Further, paper describes future methods of potential interest in orthopaedics in cooperation with engineering and technology development. In conclusion importance of numerical simulation and 3D modelling of a human hip joint is given along with their impact on personalized medicine and advantages for improving medical diagnosis and surgery (pre-operating planning).
