Abstract
Introduction: Although genetics and cumulative mechanical stress on an immature skeleton have been proposed to play a role in the development of the limbus vertebra (LV), there is no data concerning the actual degree of bone strength and bone loss in patients with LV. Aim: The aim of this study was to evaluate the bone mineral density (BMD) and the prevalence of osteoporosis in women with LV and compare with age- and body mass index-matched women. Material and Methods: This study was carried out on 171 women (aged 40–49 years) with LV and 190 women without LV. Lumbar spine BMD values were obtained by dual-energy X-ray absorptiometry. Results: A total of 361 patients were included in the study. The mean total BMD value was significantly lower (0.876 ± 0.155 vs. 0.966 ± 0.187 g/cm2, p < 0.0001), and the mean T-score value was significantly higher (-1.6 ± 1.41 vs. -0.8 ± 1.71, p < 0.0001) in patients with LV. Although the frequency of both osteopenia and osteoporosis were higher in patients with LV, the difference reached statistical significance only for osteoporosis (p = 0.007). Conclusion: Women with LV have lower BMD values and higher osteoporosis rates than age- and BMI-matched controls; therefore, osteoporosis should be evaluated in these patients.
