简要总结
This research will study the bone fragility in obese patients, on DXA and CT-scan, in a transversal study. The investigators want also to study the specific risk factors of bone fragility in these obese patients (relationship between body composition on whole body on DXA, fat mass and its location, lean mass, weight loss after surgery and SBAC-L1), to improve the bone screening.
