Traumatic sternal segment dislocation in a 3-year-old girl: Sonographic findings

Sternal fractures are uncommon in the pediatric population, and sternal segment dislocations are even rarer with only a few cases reported in the literature. Most cases are secondary to direct trauma to the chest, but nontraumatic dislocations have been reported. The diagnosis can be difficult to establish with standard radiographs, while CT is not desirable in the pediatric population due to the associated irradiation. Ultrasound (US) can be used as the first-line modality to evaluate the sternum. We report the US findings associated with a case of traumatic sternal segment dislocation in a 3-year-old girl. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:45-49, 2017.
