Fracture of the Second Rib: An Indirect Sign of Serious Trauma Like Fracture of the First Rib?

Abstract

Background: The first 3 ribs are anatomically well-protected, shielded by the large thoracic muscles, the shoulder girdle, and the arm. A significant force is required to fracture these ribs; thus, such fractures suggest a high-energy trauma and are associated with injuries to vital organs of the thorax, such as the aorta, the heart, the lungs and the great vessels.

Methods: A retrospective analysis was conducted over a 10-year period at a single hospital. The study assessed patients with fractures of the second rib, including their concurrent injuries and the overall severity of their trauma.

Results: Among the 76 patients included in the study, the average age was 47.35 years, 81.5% were men, and 19.5% were women. Thirteen patients (17.1%) survived their injuries. The most common causes of injury were road traffic accidents (63%) and pedestrian injuries (22%). The patients who did not survive sustained injuries to an average of 5 additional organs, while survivors had injuries to an average of 2.07 additional organs. Left rib fractures were the most frequently observed (46%). The most serious concurrent injuries reported were to the aorta (5.26%), heart (10.52%), lung (52.36%), head (57.89%), liver (30.2%), spleen (26.31%), and kidney (17.1%).

Conclusion: As indicators of serious injury to vital endothoracic organs, isolated fractures of the second rib should be considered equal to first rib fractures in clinical importance.
