title: Using CT of the cervical spine for early evaluation of pediatric patients with head trauma.
abstract: OBJECTIVE
  The purpose of this study was to assess the effectiveness of CT of the cervical spine in addition to radiography in pediatric patients with suspected head trauma at the time of the CT head examination.
  
  
  METHODS
  We identified 63 pediatric patients admitted to the emergency department who had head trauma and who underwent both head CT and neck radiography. Those who underwent CT of the cervical spine at the time of the head CT examination during their initial evaluation were compared for demographics, clinical status, mechanism of injury, and number of excess radiographs (number required by protocol minus number of films obtained) required to evaluate the cervical spine with those patients who did not undergo early CT of the cervical spine.
  
  
  RESULTS
  Twenty-one patients (33%) underwent cervical spine CT at the time of the head CT examination. The number of excess radiographs differed significantly between these patients (2.1 +/- 2.6 vs 3.6 +/- 2.7, p = 0.04) and the comparison group. Patients who did not undergo early CT for whom excess radiographs were obtained had the following characteristics: they were older than 8 years (p = 0.03), were unrestrained in a motor vehicle crash (p = 0.04), had a Glasgow coma score of 13-15 (p = 0.01), and were intubated (p = 0.02).
  
  
  CONCLUSIONS
  The number of repeated radiographs required to ascertain that the cervical spine is free of injury after suspected head trauma is significantly fewer when initial CT of the neck is performed at the time of head CT examination. Including cervical spine CT in trauma protocols for subgroups of children with head injuries may lead to more effective clearance of the pediatric cervical spine.
