Spinal Instability Score (SINS)
Simple scoring for Stability in Malignant Infiltration.
Scoring System.
Scored out of 18. - 0 to 6: Stable. - 7 to 12: Potentially Unstable. - 13 to 18: Unstable.
So 7 and above needs Spinal Surgeon discussion.
How good is it?
Most papers seem to be about intra and interobserver reliability.
