Skull Fractures in Pediatric Emergency Department: the Ultrasound Protocol

The aim of this clinical trial is to compare musculoskeletal ultrasound with the reference standard diagnostic test (cranial CT scan) in patients with minor head trauma associated with scalp hematoma and suspected skull fracture. The primary objective is to assess the diagnostic accuracy of point-of-care ultrasound in detecting skull fractures, in terms of sensitivity, specificity, positive and negative predictive values, and likelihood ratios, using cranial CT as the reference standard.
