Comprehensive algorithmic approach to subaxial cervical spine stability and triage.
Cervical Stability Probe
Input the fracture morphology, ligamentous status, and neurological findings to determine the SLIC stability score.

When to Use
When to Use
Determining whether a fractured cervical spine (C3 to C7) requires operative stabilization or just a hard cervical collar.
Standardized communication tool during trauma handover.

Development
Introduced by Vaccaro and the Spine Trauma Study Group (2007) because previous classification systems (like Denis or Allen-Ferguson) were overly complicated and failed to explicitly direct surgical decision making. SLIC boiled trauma down to the three things that actually matter: What is the bone doing? What are the ligaments doing? What is the spinal cord doing?

Pearls/Pitfalls
Incomplete vs Complete
It seems counter-intuitive, but an INCOMPLETE spinal cord injury (3 points) scores higher toward surgery than a COMPLETE spinal cord injury (ASIA A, 2 points). This is because an incomplete cord has surviving axons that can be salvaged by immediate decompression, whereas a complete cord transection is sadly irreversible, lowering the absolute urgency of the surgery.
