Methods: A cross-sectional study was conducted on 460 patients with multiple traumas. Data were collected from CT scan reports and analyzed using SPSS 22 software, employing independent t-tests, correlation coefficients,and chi-square tests. Results:The mean age of the patients was 40.2 ± 20.36 years (range: 16–97). Gender distribution included 28.7% women and 71.3% men. Significant differences in CT scan findings were observed based on gender (P = 0.032), trauma mechanism (P = 0.029), and clinical complaint type (P = 0.017). Patients under 20 years old exhibited more normal findings, whereas those over 40 had a higher prevalence of rib and thoracic vertebra fractures. Traffic accidents and collisions frequently resulted in rib and thoracic vertebra fractures, while altercations were more commonly associated with pneumothorax. Clinical complaints of chest pain and deformity were frequently linked to pneumothorax and rib fractures. Conclusions: These findings underscore the importance of age, trauma mechanism, and clinical complaints in diagnosing chest trauma, facilitating more informed decision-making and diagnosis. https://ajs.tums.ac.ir/index.php/ajs/article/view/276
