Abstract
We analyzed the vertebral morphometry of healthy premenopausal women and their changes with age and menopause in order to better define the reference population for the clinical and epidemiological evaluation of vertebral fractures. Vertebral morphometry has been performed on lateral thoracic and lumbar spine films from 50 premenopausal and 76 postmenopausal normal women, age range 39–74 years. Vertebral heights and the anterior height/posterior height ratio are significantly lower in postmenopausal compared with premenopausal women. Vertebral anterior height decreases about 1.5 mm/year, whereas middle and posterior height decreases about 1.3 and 1.2/mm year, respectively. A statistically significant reduction of vertebral heights by around 1 mm/vertebra was observed in postmenopausal (n=16) compared with premenopausal women (n=20) of the same age (P<0.05). The results demonstrate that vertebral heights are lower with advancing age and menopause and that the vertebral heights difference in elderly people is not only the consequence of a cohort effect. The results also contribute to better defining the reference population to be chosen for evaluatin vertebral deformation.
