Purpose: The purpose of the study was to determine if first rib fractures are associated with an increased incidence of thoracic vascular injury in pediatric patients. Methods: The medical records of all children diagnosed with a first rib fracture or a central vascular injury after blunt trauma treated at a state-designated level 1 pediatric trauma center from 2000 to 2009 were reviewed. Results: Thirty-three children (0.27% of patients; mean age, 10.9 ± 0.9 years) were identified with either a first rib fracture or thoracic vascular injury owing to blunt trauma. Thirty-two children had a first rib fracture, and only 1 child (3%) had significant thoracic vascular injury. Mediastinal abnormalities (indistinct aortic knob) were identified in 3 children, 2 with first rib fracture on initial chest radiograph. Despite a normal cardiovascular examination result, 25 (74%) children with a normal mediastinum on screening chest radiograph underwent computed tomography. No child with a normal mediastinum on initial chest radiograph was found to have associated intrathoracic injuries requiring further intervention. In children with first rib fractures and a normal mediastinum by screening chest x-ray, the negative predictive value for thoracic vascular injury was 100%. Conclusions: Children with first rib fractures without mediastinal abnormality on chest radiograph require no further workup for thoracic vascular injury.
