Résumé

Human body cimputer models are now frequently used for virtual crash tests in the early phase of vehicle prototype designs. However existing models only partially consider the extreme variability of the human body. Such variability raises the issue of subject specific modelling, both for geometry and for tissues mechanical properties. Progress in medical imaging and particularly biplanar X-Rays and associated 3D reconstruction, used in clinical routine, yielded drastic advances in geometric modelling. Progressive constitution of large databases allow interindividual variation analysis and modelling. Progress also concerns bone mechanical properties quantification. Recent ultrasound elastography techniques provide novel tools for in vivo characterization of soft tissues.  Beyond the field of road safety, research in subject specific modeling is also active in orthopedy and traumatology, for identification of subjects at risk and for orthopedic or surgical treatment based on subject specific simulation.  Computer based tools should emerge in a near future for a decision aid in diagnosis and treatment strategy planning, taking into account patient specificities and moving towards individualized medicine.

  • Biomechanical evaluation of a bioactive artificial anterior cruciate ligament 
    GUERARD, Sandra; MANASSERO, Mathieu; VIATEAU, Véronique; MIGONNEY, Véronique; SKALLI, Wafa; MITTON, David (techno-press, 2014)
    This study aimed to assess the biomechanical performance of a new generation of artificial ligament, which can be considered “bioactive” and “biointegrated,” implanted in sheep. Thirty sheep were implanted: 15 sheep received ...
  • Subject-specific body segment parameters’ estimation using biplanar X-rays: a feasibility study 
    SANDOZ, Baptiste; LAPORTE, Sébastien; SKALLI, Wafa; MITTON, David (Taylor & Francis, 2010)
    In order to improve the reliability of children’s models, the aim of this study was to determine the subject-specific masses and 3D locations of the centres of mass (CoM) of body segments using biplanar X-rays. Previous ...

  • Tibio-femoral joint constraints for bone pose estimation during movement using multi-body optimization 
    BERGAMINI, Elena; PILLET, Hélène; HAUSSELLE, Jérôme; THOREUX, Patricia; GUERARD, Sandra; CAMOMILLA, Valentina; CAPPOZZO, Aurelio; SKALLI, Wafa (elsevier, 2011)
    When using skin markers and stereophotogrammetry for movement analysis, bone pose estimation may be performed using multi-body optimization with the intent of reducing the effect of soft tissue artefacts. When the joint ...
  • Shear Wave Elastography can evaluate Annulus Fibrosus Alteration in Adolescent Scoliosis 
    LANGLAIS, Tristan; VERGARI, Claudio; PIETTON, Raphaël; DUBOUSSET, Jean; SKALLI, Wafa; VIALLE, Raphaël (2018)
    Objectives In vitro studies showed that annulus fibrosus lose its integrity in idiopathic scoliosis. Shear wave ultrasound elastography can be used for noninvasive measurement of shear wave speed (SWS) in vivo in the annulus ...
