This study was conducted to evaluate the performance of the simple clinical tool "FOSTA" in patients at our clinic using dual-energy X-ray absorptiometry (DEXA) to define osteoporosis. There are several reports on the relation between FOSTA and weight bearing bone BMD (i.e. vertebra, femoral neck, etc.) , but no report has discussed the forearm bone BMD, which is non-weight bearing bone BMD. The subjects of this study were 141 women whose forearm bone BMD was measured at our clinic. Their ages ranged from 28 to 92 (mean 68). In this study, the FOSTA index achieved 99% sensitivity and 54% specificity for osteoporosis. These results indicated that the FOSTA index is efficient for identifying Japanease women with osteoporosis, and relates well with both weight and non-weight bearing bone BMD.
