Clinical Scorecard: Creation and assessment of a nomogram for estimating necrosis risk following fingertip replantation: a retrospective analysis from a single institution

At a Glance

CategoryDetail
ConditionFingertip replantation necrosis risk
Key MechanismsClinical, procedural, and early postoperative information
Target PopulationAdults with fingertip amputation at the distal interphalangeal joint level or more distally
Care SettingSingle institution, retrospective study

Key Highlights

  • Developed a nomogram to estimate necrosis risk post-fingertip replantation
  • Study involved 1,344 patients and 1,497 fingertip replantations
  • Model performance showed strong discrimination with AUC of 0.953 and 0.974
  • Six predictors identified: surgeon experience, PLT, NEU%, D-dimer, hypertension, vascular crisis
  • Necrosis affected 12.2% of patients in derivation and 11.9% in validation

Guideline-Based Recommendations

Diagnosis

  • Use early postoperative laboratory results and vascular-crisis status for risk stratification

Management

  • Consider the identified predictors for assessing necrosis risk in fingertip replantation

Monitoring & Follow-up

  • Monitor laboratory values and vascular status post-replantation

Risks

  • Necrosis can impair psychological health and affect hand appearance and function

Patient & Prescribing Data

Adults with fingertip amputations requiring replantation

Nomogram designed for early postoperative risk assessment

Clinical Best Practices

  • Utilize the nomogram for estimating necrosis risk in clinical settings
  • Ensure thorough documentation of postoperative vascular status
  • Incorporate laboratory findings into decision-making for fingertip replantation outcomes
