Abstract
Background: Ultrasound is an attractive modality for the confirmation of sternal fractures in patients with trauma because of its easy, quick, and accurate nature, as well as its increased availability for focused assessment with sonography for trauma at the bedside. We aimed to confirm the diagnostic value of ultrasonography for sternal fractures in patients with trauma, anterior chest wall pain, and tenderness. Methods: This retrospective observational study included patients visiting a single regional trauma center from March 2022 to February 2023, diagnosed with sternal fractures via chest CT and bone scans, who underwent sternal ultrasound. Results: Twenty-six patients were divided into two groups: those with sternal fractures diagnosed with an initial chest CT scan (n = 19) and those without fractures (n = 7). Using ultrasound, 23 patients (88.5%) were diagnosed with sternal fractures. In the initial CT scan (+) group, all 19 patients (100%) were diagnosed using ultrasound. In the initial CT scan (-) group, four (57.1%) of the seven patients were diagnosed using ultrasound. In the initial CT scan (+) group, 14 (73.7%) of the 19 patients underwent bone scans and all 14/14 (100%) were diagnosed with sternal fractures. In the initial CT scan (-) group, seven (100%) patients underwent bone scans, and all were diagnosed with sternal fractures. Conclusions: Ultrasound is useful for the diagnosis of sternal fractures, with sensitivity of 88.5%. Therefore, in patients with blunt trauma experiencing anterior chest wall pain and tenderness, sternal ultrasonography might be helpful in diagnosing sternal fractures as an adjunct to chest CT and bone scans.
