- Abstract
Objective In order to improve the diagnosis of vertebral fracture, VFA was performed during the BMD measurement. Methods VFA were consecutively performed during the BMD measurement of proximal femur in 217 postmenopausal women whose ages were over 50 years. Vertebral fracture evaluation software was used to find vertebral body fractures. According to T scores, the patients were divided into the group with BMD T > -2.5 and the group with BMD T ≤ -2.5. According to the age, the patients were divided into 50-59 yrs group, 60-69 yrs group, and ≥70 yrs group. According to the duration of menopause, the patients were divided into 0-9 yrs group, 10 - 19 yrs group, and ≥20 yrs group. The effect of BMD, age, and duration of menopause on the vertebral fracture was analyzed. In order to understand the agreement of the vertebral fracture assessment with VFA, the patients' images were performed repeatedly to assess the accordance of the evaluation by the same researcher in 2 months. The reproducibility was estimated using Kappa method. Results The vertebral fracture rate was 21. 6% in the patients with BMD T > -2. 5 and 34. 8% in the patients with BMD T ≤ -2.5. The vertebral fracture rates were 12. 5%, 25. 6%, and 44. 8% in the age groups of 50 - 59 yrs, 60-69 yrs, and ≥70 yrs, respectively. The vertebral fracture rate was significantly higher in the patients with long duration of menopause. The reproducibility indicated almost perfect agreement. Conclusion BMD measurement together with VFA for postmenopausal women at same time improves the diagnosis of vertebral fracture and osteoporosis.
