🦴 SINS (Spinal Instability Neoplastic Score)
UseWhen to use: metastatic spine lesion stability triage with oncology/spine teams.
Strata0–6 stable; 7–12 indeterminate; 13–18 unstable.
LimitsWhen not to use: primary infection/trauma pathways. · Pitfall: missing mechanical pain. · Not a sole surgical booking.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Location | 1 — semi-rigid (T3–T10) |
|---|---|
| Pain | 1 — occasional / nonmechanical |
| Bone lesion | 1 — mixed |
| Radiographic spinal alignment | 2 — kyphosis / scoliosis |
| Vertebral body collapse | 1 — no collapse with >50% body involved |
| Posterolateral involvement | 1 — unilateral |
→SINS7/18
- Cue：7–12 — indeterminate (possible impending)
| Location | 0 — rigid (S2–S5) |
|---|---|
| Pain | 0 — pain-free lesion |
| Bone lesion | 0 — blastic |
| Radiographic spinal alignment | 0 — normal |
| Vertebral body collapse | 0 — none |
| Posterolateral involvement | 0 — none |
→SINS0/18
- Cue：0–6 — stable

FAQ
Frequently asked questions
- Does SINS (Spinal Instability Neoplastic Score) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is SINS (Spinal Instability Neoplastic Score) calculated in practice? Can you show a worked example?
- Inputs: Location 1 — semi-rigid (T3–T10), Pain 1 — occasional / nonmechanical, Bone lesion 1 — mixed, Radiographic spinal alignment 2 — kyphosis / scoliosis, Vertebral body collapse 1 — no collapse with >50% body involved, Posterolateral involvement 1 — unilateral → Result: SINS 7 /18（Cue: 7–12 — indeterminate (possible impending)） Inputs: Location 0 — rigid (S2–S5), Pain 0 — pain-free lesion, Bone lesion 0 — blastic, Radiographic spinal alignment 0 — normal, Vertebral body collapse 0 — none, Posterolateral involvement 0 — none → Result: SINS 0 /18（Cue: 0–6 — stable）
