Background

  • US and Canada with more than 13 million trauma pts per year at risk for C-spine injury
  • Most blunt trauma patients will be placed in a cervical collar by EMS to protect the C-spine
  • C-spine can be clinically cleared by trained personnel

Clinical Features

C-spine injuries may present with

  • rarely neurogenic shock (bradycardia, hypotension)
  • posterior neck pain
  • pain on palpation of spinous processes
  • limited neck ROM with pain
  • weakness, numbness, or paresthesias

Decision Rules

NEXUS Cervical Spine Rule

Radiography is not necessary if the patient satisfies ALL of the following low risk criteria:

  • No midline cervical tenderness
  • No focal neuro deficits
  • Normal alertness
  • No intoxication
  • No painful distracting injury

C-spine imaging should be considered unless the patient meets all of the above low risk criteria[1] [2]

Canadian Cervical Spine Rule

Algorithm for evaluation of cervical spine injuries (Canadian C-spine Rule)

No High Risk Factors

  • Age >65
  • Dangerous mechanism (fall>3ft/5 stairs, high speed MVC (>60mph)/rollover/ejection, bicycle crash, RV, axial load injury)
  • Parasthesias in extremities

ANY Low Risk Factor

  • Simple rear end MVC
  • Delayed onset of pain
  • Sitting position in ED
  • Ambulatory at any time
  • Absence of midline C-spine tenderness

ROM

  • Rotates neck 45 degrees to left and right

C-spine can be cleared clinically if above criteria met[3] [4]

Canadian rule vs. Nexus

A single trial showed Canadian rule would pick up 312 or 313 clinically important cases, while NEXUS would miss 1 one in 10 cases[5]

Sensitivity

Canadian 99.4% vs Nexus 90.7%

Specificity

Canadian 45.1% vs. Nexus 36.8%

Management

Criteria Met

  • If CCSR or NEXUS criteria is met, patient can be cleared clinically

Criteria Not Met

  • If unable to be cleared by CCSR or NEXUS then imaging is indicated with CT C-spine is indicated
    • CT recommended over xray
    • For significant injury CT has a sensitivity of 100% while xray has a sensitivity 36%[6]
  • CTs/Xrays not adequate to assess for ligamentous instability
  • If pt continues to have midline pain after adequate pain control obtain MRI (potentially as outpatient)
    • Keep C-collar until MRI results or pain resolves

Obtunded Patient

  • C-Spine management unclear in the obtunded adult patient with blunt trauma after negative CT C-spine
  • EAST (Eastern Association for the Surgery of Trauma) performed systematic review in 2015[7]
    • Review included 1800 obtunded patients generally defined as GCS<13 with negative CT c-spine using <3mm axial cuts
    • Of 1800 patients, 176 patients with abnormal MRI
    • None (or 0/176) had unstable C-spine injury
    • EAST guideline notes: We conditionally recommend cervical collar removal after a negative high-quality C-spine CT scan result alone[8]

Disposition

  • Based on imaging results
