Abstract

Introduction

Although remarkable progress has been made in osteoporosis treatment over the last two decades, no study has reported the change in the prevalence of vertebral fractures (VFs) during this time. This study aimed to compare the prevalence and pattern of VFs at three time points from 1997 to 2019 in a Japanese medical examination-based study.

Materials and methods

The participants of this study were inhabitants of a typical Japanese mountain village who participated in these surveys at three time points: 1997 (group A), 2009 or 2011 (group B), and 2019 (group C). The age- and sex-adjusted groups were defined as groups A’, B’, and C’, respectively (39 men and 85 women; mean age 73.6–74.0 years old). The type and extent of deformities of the prevalent fractures from T4 to L4 on the lateral thoracic and lumbar spine radiographs were semiquantitatively evaluated.

Results

The prevalence of VFs has significantly decreased over the past two decades. In group A, the percentages of thoracic level, biconcave type, and severe deformity of VFs were significantly higher than expected. The bone mineral density of the participants increased significantly over time. The treatment rate for osteoporosis in participants with osteoporosis has improved over the past two decades.

Conclusion

This study demonstrated that the prevalence of VFs has decreased, and the pattern of VFs has changed over the last two decades in a typical Japanese mountain village due to multifactorial improvements in skeletal fragility, including improvement in osteoporosis treatment rate.
