The proposed methodology combines different approaches from modeling to 3D simulation.
The simulation is based on patient-specific anatomical models, where acquisition modalities are non invasive and flexible. Based on static MRI (Magnetic Resonance Imaging) data, a discrete deformable models method is used for modeling the organs of the musculoskeletal system. Femoroacetabular movements are estimated using an optical motion capture system and are validated by a dynamic MRI analysis. To achieve accurate deformations, techniques to generate volumetric meshes are developed based on the medial axis information. Finally, a computationally-efficient fast functional joint model is used to simulate the mechanical behavior of the soft tissues. The goal of such a simulation is to allow the investigation of the relevant contact and cartilages deformation under movement, which can be useful for diagnosis, pre- or post- operative planning and training. This will benefit further developments in surgical techniques and minimally invasive procedures. A complete case study has been done on 6 ballerinas who perform daily extreme motions. It was possible to identify the cartilage deformation while a ballerina was dancing. We have also shown a correspondence with the information obtained from MRI data set.
