    A nomogram was developed to estimate necrosis risk following fingertip replantation using clinical and early postoperative data.

  • 2

    The study analyzed 1,344 patients with 1,497 fingertip replantations from August 2018 to August 2023.

  • 3

    Six predictors were identified for the nomogram: surgeon experience, PLT, NEU%, D-dimer, hypertension, and vascular crisis.

  • 4

    The model demonstrated strong discrimination with an area under the curve of 0.953 for derivation and 0.974 for validation.

  • 5

    Calibration results indicated an intercept of -0.338 and slope of 0.759, with a Hosmer–Lemeshow test P-value of 0.729.
