Beside the bone mass, structural changes are important determinants of the bone strength. Patients with osteoarthritis (OA) seem protected against femoral neck (FN) fracture. When compared to osteoporosis, FN in OA are characterized by a higher bone mass and a better trabecular microarchitecture (Blain et al., 2008, Boutroy et al., 2011). The presence of microcracks is one of the determinants of the bone strength. The aim of this study was to evaluate the mic...

Background: While the relationship between visceral (VFAT) and subcutaneous (SFAT) fat mass with cardiometabolic risk has been demonstrated in adults, fat mass evolution during teenagehood remains poorly explored and usually assessed with irradiative (CT) or expensive (MRI) techniques. Our aim was to evaluate a novel technique derived from DXA to assess VFAT and SFAT in healthy teenagers.Subjects and methods: Healthy teenagers from the VITADOS study unde...

Introduction: The first clinical applications of FE-strength estimates to classify osteoporotic fractures showed inhomogeneous results. We developed a FE model that correlated well with femur strength in-vitro (R2=0.9, 14 femurs). This work aims to verify if our model can classify osteoporotic fractures in three case-control studies: a retrospective and a prospective study on proximal femur fracture, and a retrospective study on prevalent ...
