Abstract Background Vertebral fracture is the most common fragility fracture but it remains frequently unrecognized and is underdiagnosed worldwide. In this retrospective study, we examined the prevalence of moderate and severe vertebral fractures on chest radiographs of hospitalized female patients aged 50 years and older and determined missed diagnosis of vertebral fractures in the original radiology reports. Methods 3216 female patients 50 years of age and older were enrolled in our study. The patients’ medical records including their original radiology reports and lateral chest radiographs were retrospectively reviewed by the study radiologists who had training certificates from the International Society for Clinical Densitometry (ISCD). Vertebral fractures between thoracic spine T4 and lumbar spine L1 were identified and classified using Genant’s semi-quantitative scale. The definition of vertebral fractures used in this study was Genant grade 2 or higher. Results The study radiologists identified 295(9.2%) patients with grade 2 or 3 fractured vertebrae, total 444 vertebrae on 3216 chest radiographs. The prevalence of vertebral fracture was 2.4% in women aged 50-59 yrs., 8.9% in women aged 60–69 yrs., and 21.9% in women aged≥70 yrs. There were 213 patients with a single vertebral fracture, 49 patients with two vertebral fractures and 33 patients with ≥ three vertebral fractures. Fractured vertebrae were identified with greater frequency in thoracic spine T11,12 and lumbar spine L1. According to our statistics, 66.8% of patients with vertebral fractures found in this study were undiagnosed in the original radiology reports. Conclusions Vertebral fracture is common on chest radiographs but it is often ignored by radiologists. Genant’s semiquantitative assessment is a simple and effective method for detecting vertebral fracture. Because osteoporotic vertebral fracture increases the risk of new fractures, radiologists have an important role in accurately diagnosing vertebral fractures.
