N.E.X.U.S. = National Emergency X-ray Utilization Study
Utility: if criteria fulfilled, low risk for spinal injury and c-spine can be cleared without the need for imaging
- Normal level of alertness
- Not intoxicated
- No midline cervical spine tenderness
- No other painful injuries that may distract the patient from a less painful (but broken) neck
- No focal neurologic deficits
Only if patient fulfills all 5 criteria – then forego imaging. Otherwise, proceed with imaging.
Mnemonic: NSAID (neuro deficit, spinal tenderness, AMS, intoxication, distracting injury)
