The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (OXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMO) at proximal femur and spine were obtained by dualenergy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a OEXA T-score <-2.5 at the femoral neck or lumbar spine. Sensitivity, specificity and kappa statistics for OXL were calculated, assuming the OEXA measurement as the gold-standard. The study included 475 women with a mean age of 54± 11.9 years. 15% had osteoporosis while 39% were osteopenic (-2.5
