    Abstract:
    BACKGROUND: Scapular fractures in the pediatric population are rare, and medical literature is lacking regarding these specific injuries in the pediatric population. Prior studies have shown that scapular fractures resulting from blunt chest trauma have been associated with significant morbidities in adults, and that a majority of scapular fractures are missed on chest X-ray (CXR) and seen on computerized tomography only (SOCTO). Further guidance is needed regarding the prevalence of coinciding injuries in the pediatric population and the modality for diagnosis. OBJECTIVES: The primary objectives of this study were to assess 1) the frequency of scapular fractures following blunt trauma in the pediatric cohort, 2) the frequency of other associated thoracic injuries, 3) the proportion on scapular fractures SOCTO. METHODS: We conducted a retrospective cohort study with data obtained from our study site's Trauma Registry. Patients under 18 years receiving both a CXR and chest CT following blunt trauma or any patient diagnosed with a scapular fracture by any modality from January 2009 to December 2019 were included. Primary outcome variables were the presence of a scapular fracture diagnosed by any modality, absence of scapular fracture, and scapular fractures SOCTO. Charts were also reviewed for the following concurring injuries: 1) contusion/atelectasis, 2) pneumothorax, 3) hemothorax, 4) rib fracture, 5) other fracture, 6) vascular injury, 7) mediastinal injury, 8) diaphragm rupture, 9) foreign body, 10) incidental finding. RESULTS: Of 12,826 charts of pediatric patients with blunt chest trauma, 1405 obtained both CXR and chest CT. Sixty (0.47%) were diagnosed with scapular fracture, and 48 (73.3%) of the fractures were SOCTO. The most commonly associated injuries were other fracture (88.3%), lung contusion/atelectasis (78.3%), pneumothorax (58.3%) and rib fracture (58.3%). Patients with scapular fractures had higher injury severity scores (ISS) and more frequently required surgery for other intrathoracic injuries. Only five patients required surgical management of the scapular fracture with the rest managed conservatively. CONCLUSION: Pediatric scapular fractures are rare and are often associated with other intrathoracic injury. A majority of scapula fractures are missed on CXR, but identification of the injury did not change management as most were treated conservatively.
