A just released study published in the Lancet gives us guidance on which pediatric blunt trauma patients need cervical spine imaging. Age range was 0-17 years.

In children without high-risk findings, 5 additional findings identified children with intermediate, non-negligible risk of CSI (3.6% risk of a cervical spine injury):
