Abstract : Background: The aim of this study was to investigate vertebral geometry changes and determine cutoff value of vertebral height to predict fractures.Methods: In a cross-sectional study, 280 postmenopausal women recruited In all subjects bone mineral density and radiography of the lumbar spine performed. Lateral radiographs were evaluated for identification of vertebral fractures, using a validated semiquantitative method. T-score of vertebral height was calculated based on data extracted from Iranian Multicenter Osteoporosis Study. ROC curve used to determine cut off value of vertebral height T-score to predict fractures. Results: The mean of age and BMI were 55.34▒آ8.7 years and 27.73▒آ5 kg/m2, respectively. Among osteoporotic women, 59.8percent had one or more vertebral fractures and 23.8percent had at least 2 fractures. In fracture group the T-score of spine and femur BMD was lower than the others. The mean of vertebral height in women without fractures was 12.94▒آ0.6 cm, and in the patient with 4 or more fractures was 12.3, thus every fracture accompany with 1.2percent decreases in the height of vertebrae.The prevalence of vertebral fracture in osteoporotic patients was 71.4percent and in healthy cases 39.5percent. Better estimation of vertebral height T score in ROC curve was less than -0.7.The sensitivity and specificity of the cut off value were 81.3percent and 52.9percent, respectively.Conclusion: Vertebral fractures are common fractures in postmenopausal women. There was a correlation between vertebral height and fractures. Vertebral geometric parameters especially height T score can be used for fracture screening.
