Rib Fractures in Trauma Patients: Prevalence, Associated Injuries, and Mortality Trends

Abstract

Introduction Rib fractures are a common consequence of thoracic trauma, often signaling the presence of additional injuries and increasing the risk of mortality. This study aimed to elucidate the frequency, patterns, and mortality rates associated with rib fractures in multitrauma patients and to explore the association between rib fractures and other systemic injuries. Methods In a retrospective observational study at a tertiary care hospital, electronic medical records of multi-trauma patients over a four-year period were examined. Inclusion criteria encompassed adult patients who had undergone whole-body or chest and abdomen CT imaging. The study evaluated the incidence and location of rib fractures, associated thoracic and intra-abdominal injuries, and the in-hospital mortality rate. Results Among the 1,338 patients analyzed, rib fractures were identified in 273 (20.4%), with a median age of 33 years and 199 (72.9%) were male. Motor vehicle accidents were the most common trauma mechanism with a rate of 52% (n=142). Patients with rib fractures had significantly higher occurrences of pneumothorax (25.3%), hemothorax (20.9%), and intra-abdominal injuries (17.5%) (p<0.001). Notably, patients with six or more rib fractures exhibited a higher frequency of liver, spleen, and kidney injuries (p=0.003, p=0.011, p=0.001, respectively). The in-hospital mortality rate was 5.9% (n=17) for patients with rib fractures, significantly higher than those without (p<0.001). Conclusion Rib fractures in multi-trauma patients are an important indicator of severe concurrent injuries and are associated with a higher mortality rate. These findings advocate for a systemic and immediate evaluation of patients with rib fractures upon presentation in emergency departments to improve survival outcomes.
