Pediatric head trauma is common, but computed tomography exposes children to ionizing radiation. This systematic review and meta-analysis evaluated the diagnostic accuracy of point-of-care ultrasound for pediatric skull fractures and clarified its role as an adjunct to clinical assessment rather than a replacement for computed tomography when intracranial injury is suspected.
Methods
We conducted a systematic review and bivariate random-effects diagnostic test meta-analysis guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement and registered in the International Prospective Register of Systematic Reviews (Registration Number: CRD420251139217). PubMed, Embase, the Cochrane Library, and Web of Science were searched from inception through 3 September 2025. Two reviewers independently screened studies, extracted 2 × 2 diagnostic data, and assessed risk of bias using the Quality Assessment of Diagnostic Accuracy Studies-2 tool.
Results
Nine studies conducted in emergency department settings met the inclusion criteria. Point-of-care ultrasound demonstrated a pooled sensitivity of 0.90 (95% confidence interval: 0.84–0.94), specificity of 0.98 (95% confidence interval: 0.94–0.99), and an area under the summary receiver operating characteristic curve of 0.96 (95% confidence interval: 0.94–0.97). The summary positive likelihood ratio was 41.73 (95% confidence interval: 15.85–109.87), and the negative likelihood ratio was 0.10 (95% confidence interval: 0.07–0.17). Deeks’ funnel plot showed no evidence of small-study effects (P = 0.80).
Conclusions
Point-of-care ultrasound shows high diagnostic accuracy for detecting pediatric skull fractures and may support bedside risk stratification in selected children with low- or intermediate-risk mild head trauma. However, most isolated linear skull fractures are managed conservatively, and point-of-care ultrasound does not evaluate intracranial injury. Computed tomography decisions should therefore remain anchored in neurological status, injury mechanism, validated pediatric head injury decision rules, and clinician judgment.
