Prevalence of morphometric vertebral fractures in osteoporotic patients in Greece: the Vertebral Integrity Assessment (VERTINAS) study

Our purpose was to assess the prevalence of morphometric vertebral fractures (VFs) in osteoporotic patients in our country. We found that 25.4% of patients had sustained a VF, and the majority of them (76.6%) were undiagnosed prior to inclusion in this study. Introduction We assessed the prevalence of morphometric vertebral fractures (VFs) in osteoporotic patients in our country. Methods Patients were recruited via announcements by the national media, their attending physicians or the National patients' Society. Inclusion criteria were (1) age > 50 years, (2) postmenopausal status > 2 years (women), (3) > 1-year use of medication for osteoporosis and (4) lack of radiological vertebral assessment for > 1 year. Exclusion criteria were (1) bone metabolic diseases other than osteoporosis, (2) patients with secondary osteoporosis, (3) patients with inability to stand/walk, (4) previous high-energy VFs. All patients performed lateral X-rays of the thoracic and lumbar spine that were evaluated separately both by certified radiologists on site as well as 3 consultant orthopaedic surgeons remotely through a specifically designed web database system. The Genant semi-quantitative method was used for the classification and grading of VFs and statistical analysis of the results was performed. Results One thousand six hundred fifty-two patients (1516 female, 70.02 +/- 8.28 years; 136 male, 74.78 +/- 8.25 years) were included in the final analysis. The prevalence of VFs was 25.4%, 76.6% of fractured patients were previously undiagnosed, and of these 39.9% had > 1 VFs. The most common fracture was T12, most fractures were found to be mild (grade 1) across all age groups, and patients 70-79 years and > 80 years were found to have a statistically significantly higher number of fractures than younger patients (p < 0.001). Conclusions Our results of the high prevalence of morphometric VFs emphasise the need for baseline assessment of vertebral fragility in patients receiving treatment for osteoporosis, as well as follow-up radiographs at specified time periods while on therapy.

Automated summary

The study aimed to assess the prevalence of morphometric vertebral fractures (VFs) in osteoporotic patients in the country. Results showed that 25.4% of patients had VFs, with the majority of them (76.6%) being undiagnosed prior to inclusion in the study.
