SINBAD Diabetic Foot Ulcer Score
SINBAD diabetic-foot-ulcer score (Ince 2008): Site, Ischemia, Neuropathy, Bacterial infection, Area, and Depth, each 0/1; total 0-6, with >= 3 predicting a poorer outcome.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Site: mid- or hindfoot
- Yes
- Ischemia
- Yes
- Neuropathy
- Yes
Result: SINBAD 3 of 6 — higher risk of poor outcome (>= 3).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 3
- Lower risk.
- >= 3
- Higher risk of non-healing / amputation (Site + Ischemia + Neuropathy + Bacterial infection + Area + Depth, each 0/1). A prognostic score, not a diagnosis.
What you enter
- Site: mid- or hindfoot (vs forefoot)
- Ischemia: pedal pulses absent
- Neuropathy: protective sensation lost
- Bacterial infection present
- Area >= 1 cm^2
- Depth: reaches muscle/tendon/bone
