Defining pediatric cervical spine clearance with computed tomography: A prospective observational study by the Western Pediatric Surgery Research Consortium and Western Trauma Association

Introduction: The optimal imaging strategy for pediatric cervical spine clearance remains controversial. The primary objective of this study was to determine the sensitivity of computed tomography (CT) in detecting clinically significant cervical spine injury in children. We hypothesized that CT is sufficiently sensitive to allow for definitive clearance of the pediatric cervical spine after blunt trauma. Methods: We conducted a prospective, multicenter, observational study from March 1, 2022, to July 31, 2025, at 72 diverse adult, mixed, and pediatric trauma centers across the United States. All children <18 years who underwent cervical spine imaging after blunt trauma were included. The primary outcome was the ability of CT to identify a clinically significant cervical spine injury requiring operative intervention or halo placement. We performed a post hoc panel review of all cases with normal imaging that required surgery. The diagnostic test characteristics and 95% CI of CT were calculated. Results: We prospectively enrolled 19,651 pediatric patients, of whom 12,693 (65%) underwent cervical spine CT and comprise the analytic cohort. The median age was 12 (interquartile range, 6-15), 37% (n=4,673) were female, and 19% (n=2,389) were obtunded, defined as GCS ≤13. The sensitivity of CT at the treating hospitals to identify a clinically significant injury was 94.7% [CI: 89.4%-97.5%], with a negative predictive value of 99.9% [CI: 99.9%-100%].
