Cervical spine injuries (CSI) are serious neck injuries but not common in kids. When kids get hurt, they might be put on a stiff neck collar and a longboard to keep the neck still. This is called spinal precautions. But sometimes, these precautions are used too often and can cause harm, like unnecessary X-rays or scans that expose kids to radiation. Too much radiation can increase the risk of cancer later in life. This study is developing a new tool to help decide when kids really need these precautions and tests, so they are only used when truly necessary.

• The study is for children aged 0-17 who have had a blunt trauma (like a car accident).
• Participation may involve being evaluated by a trauma team or having neck imaging tests.
• Kids with injuries from things like gunshots or stab wounds are not included.
