Aim: This study was conducted to assess the risk of fracture in postmenopausal women using dual x-ray absorptiometry bone mineral density (DEXA-BMD) as a reference method and FRAX as a new clinical risk assessment tool. Material and Method: 168 postmenopausal women (>50 years) evaluating with DEXA-BMD and FRAX methods were included in the study. Femoral BMD (F-BMD), femoral T-score (F-Ts), lumbar spine BMD (L-BMD) and lumbar spine T-score (L-Ts) values of the patients were calculated. Fracture risk assessments were carried out using T-score values and FRAX 10-year hip fracture (HF) and major osteoporotic fracture (MOF) risk ratios. Data were analyzed statistically. Results: According to the results of F-Ts and L-Ts, 44/168 (26.2%) and 65/168 (38.7%) of patients had osteoporosis as compatible with high fracture risk. In osteoporotic patients, mean values for F-Ts L-Ts, F-BMD and L-BMD were -2.8 +/- 0.4, -3.2 +/- 0.5, 0.530 +/- 0.049 and 0.682 +/- 0.066, respectively. There were found to be high MOF risk in 16/168 (9.5%) and high HF risk in 51/168 (30.4%) of patients according to FRAX. Positive correlations were determined between F-Ts and L-Ts (moderate; rho = 0.424, p < 0.05) and between HF and MOF (strong; rho = 0.958, p < 0001). There were strong negative correlations among HF and MOF with F-Ts (respectively, rho = -0.897 and rho = -0.844, p < 0.001) and moderate negative correlations among HF and MOF with L-Ts (respectively, rho = -0.535 and rho = -0.567, p < 0.05). Discussion: In postmenopausal women with osteoporosis, risk assessment by the FRAX besides the DXA-BMD measurements can be useful for not to be missed of patients with high risk of fracture.
