Six‐Month Outcomes After Transmetatarsal Amputation in Diabetic Patients: Predictive Utility of the SINBAD Classification

This study retrospectively reviewed 46 patients undergoing transmetatarsal amputation (TMA) between January 2017 and January 2023 to evaluate complication rates within 6 months and assess the predictive value of the SINBAD classification for re‐amputation risk. Patients were categorised based on re‐amputation occurrence, and clinical and demographic data were collected. Each case was evaluated using the SINBAD scoring system, with logistic regression used to assess associations. Among the patients, 28 (60.9%) experienced no re‐amputation, while 18 (39.1%) underwent re‐amputation. Baseline demographics and laboratory findings did not significantly differ between groups. The mean SINBAD score was significantly higher in the re‐amputation group (3.67 vs. 2.29; p < 0.001), with logistic regression identifying SINBAD score as an independent predictor (OR 6.76; 95% CI: 2.18–21.02; p < 0.001). A SINBAD score of ≥ 4 was associated with a re‐amputation rate of 90.9%. In conclusion, the SINBAD classification proves to be a simple and effective tool for predicting re‐amputation post‐TMA, facilitating risk stratification and surgical planning for diabetic foot ulcer patients.
