New methodologies for the assessment of bone mass from by dual-energy X-ray absorptiometry (DXA) have been development in the last years. The three-dimensional analysis of the proximal femur by (3D-DXA) allows the evaluation of cortical and trabecular bone separately and has shown a good correlation with computed tomography. Aim: to obtain reference values in healthy population of both sexes in Argentina. Subjects and method: Adults female and male subjects (n=992) from four cities from Argentina were included. BMD (g/cm2) was measured by DXA on femoral neck and total hip. The 3D analysis was performed with 3D-Shaper software (v2.9, Galgo Medical, Spain). The cortical BMD (sDens - mg/cm2) and trabecular volumetric BMD (trab vBMD - mg/cm3) were consider. The distribution of the data was evaluated with the Shapiro-Wilk test and parametric or non-parametric tests were used as appropriate. Data were expressed as mean±SD and p
