SINS (Spinal Instability Neoplastic Score)
SINS (SOSG, Fisher/Bilsky 2010)Sums six clinical and imaging components — location, mechanical pain, bone lesion quality, alignment, vertebral body collapse, and posterolateral element involvement — into the 0–18 Spinal Instability Neoplastic Score, banded stable / indeterminate / unstable.

How this tool works
The Spinal Instability Neoplastic Score (Fisher, Bilsky and the Spine Oncology Study Group, 2010) provides a reproducible, evidence-based measure of mechanical stability for spinal segments involved by tumor. Junctional segments, mechanical (load-related) pain, lytic bone destruction, deformity or translation, greater vertebral body collapse, and bilateral posterolateral element involvement each add points, to a maximum of 18. Totals of 0–6 are considered stable, 7–12 indeterminate (potentially unstable), and 13–18 unstable; the SOSG recommends surgical consultation for any score of 7 or higher. SINS characterizes mechanical stability only and is designed to complement — not replace — multidisciplinary frameworks such as NOMS that incorporate neurologic, oncologic, and systemic considerations.
