Subaxial cervical spine injury classification

The subaxial cervical spine injury classification (SLIC) and severity score is a system for cervical spine trauma that helps guide treatment and predicts prognosis.

Classification

Three parameters are assessed, two being radiologic determined and the last being a clinical assessment.

Injury morphology
Discoligamentous complex
  • intact: 0 points
  • indeterminate (e.g. isolated interspinous widening, MRI signal change only): 1 point
  • disrupted (e.g. disc space widening, facet perch or dislocation): 2 points
Neurological status
  • intact: 0 points
  • root injury: 1 point
  • complete cord injury: 2 points
  • incomplete cord injury: 3 points
  • incomplete with ongoing cord compression: 4 points

Treatment

  • ≤ 3 points: nonsurgical
  • 4 points: indeterminate
  • ≥ 5 points: surgical
Fractures
