Three Part Question
In [alert children with suspected cervical trauma] is [clinical examination without cervical radiography] adequate to [exclude significant cervical injury]?
An 11 year old boy is brought to the emergency department by paramedics after falling off his bicycle. They have immobilised his cervical spine with a hard collar. He has no visible external injury, is fully alert and co-operative and does not complain of any neck pain. You are aware of the “trend” for radiographic cervical spine imaging in virtually all blunt trauma patients, as unrecognised cervical spine injury can lead to disastrous neurological sequelae. However, you wonder whether imaging in this case is really necessary.

Altogether, 298 papers were identified of which 2 were relevant. In addition NICE are undergoing a systematic review of head and cervical spine injury, and checking their search results, we found 1 additional paper that has not yet been indexed by Medline. These 3 papers are shown in the table.
|Author, date and country
||Study type (level of evidence)
|Laham JL et al,|
|268 children aged 0-19, with apparent isolated head injuries defined by clinical and radiographic evidence in a single children’s hospital
Low-risk criteria for c-spine injury: capable of verbal communication and no neck pain||Retrospective cohort study||Performance of low-risk criteria for excluding c-spine injury||No cervical spine injuries in the low risk group (n=135). 10 (7.5%) cervical injuries in the high risk group. (n=133)|
|The entry criteria of: significant head injury needing admission was made at the discretion of the PICU triage officer
GCS was not consistently recorded in these children
215 children had cervical radiographs (80%)|
|Viccellio P, et al.|
|Multicenter evaluation of 3065 children (age <18) with suspected c-spine injury who underwent clinical evaluation prior to c-spine radiography
Low-risk criteria (Nexus criteria) were defined as absence of: 1) midline cervical tenderness, 2) painful distracting injury, 3) altered alertness, 4) neurological deficit, and 5) intoxication||Prospective cohort study||Performance of low-risk criteria for excluding c-spine injury||No child in the low-risk group of 603 patients had a c-spine injury.|
Nexus criteria identified all cases of cervical injury diagnosed by radiography
Sensitivity 100% (CI 87.8% - 100%)
|Number of children with cervical spine injury under nine was very low (only 4)
Total number of children with cervical injury was only 30 (0.98%), therefore, CI for sensitivity was wide (87.8-100.0%)
Caution is suggested for applying the Nexus criteria for children under 9 years|

Although the issue of radiographic assessment of children with suspected cervical injury has been addressed in several studies, there is still insufficient evidence to support diagnostic standards, as the incidence of cervical injuries amongst paediatric samples is low. To date, the Nexus criteria (absence of: 1)midline cervical tenderness, 2) altered alertness, 3) intoxication, 4) neurological deficit and 5) painful distracting injury) provide the most reliable instrument for assessing the need for cervical spine radiography in paediatric blunt trauma victims. However, in doubtful individual cases, decision should be at the clinician’s discretion, as these criteria may not be 100% sensitive, due to the wide confidence interval around these findings.
Clinical Bottom Line
Cervical spine radiography is not necessary in paediatric blunt trauma victims over the age of nine who are fully alert, conversant, show no signs of intoxication, have no neurological deficit, no midline cervical tenderness and no painful distracting injury.
