<h3>Background</h3> Osteoporosis is one of the main public health problems, leading to the appearance of fragility fractures. Within these, there are vertebral fractures, which in their vast majority have an asymptomatic course, which is why they are presented as incidental findings in imaging studies. <h3>Objectives</h3> To estimate the prevalence of insufficiency fractures in the thoracic vertebrae in patients hospitalized for any cause in a Hospital in Bogotá (Colombia). <h3>Methods</h3> Cross-sectional study in a sub population of Latin American patients, older than 50 years with chest tomography indicated during hospitalization in 2020 for reasons other than suspicion of vertebral bone disease. Patients with secondary causes of vertebral fracture, trauma and spinal instrumentation were excluded. Reading by two independent expert researchers with Genant's semiquantitative visual method and the ABQ method. Clinical and sociodemographic variables were captured (RedCap).Descriptive statistical analysis (STATA 17). The project was approved by the ethics committee. <h3>Results</h3> A total of 317 patients with a mean age of 69.4 years and a predominance of males (57.1%) were included. The most frequent personal history was active smoking (15.8%), use of glucocorticoids in the last 5 years (12.9%), and alcohol consumption (7.5%). A prevalence of vertebral fractures of 8.5% was found, being more frequent in women in 51.8% of the cases, with T11 as the most frequent location (See Table 1 and Figure 1). Only two vertebrae did not define a fracture according to the ABQ method compared to Genant. A disagreement was found in 77.7% of the cases with respect to the final report. <h3>Conclusion</h3> The prevalence of vertebral fractures reported here is lower than that reported in the literature when x-ray imaging is used; it is possible that the use of the tomography influences this result and possibly allows a more objective assessment. Careful evaluation of chest tomographic studies performed during the hospital stay may contribute to an opportune diagnosis of insufficiency fracture associated with osteoporosis. <h3>REFERENCES:</h3> NIL. <h3>Acknowledgements:</h3> NIL. <h3>Disclosure of Interests</h3> None Declared.
