Insights

Pediatric polydactyly diagnoses and surgeries have declined. Suture ligation rates remain stable, with surgery being more costly and linked to younger age and higher comorbidities.

Area of Science:

  • Pediatric Orthopedics
  • Hand Surgery
  • Health Services Research

Background:

  • Polydactyly management and surgical trends lack comprehensive characterization.
  • Understanding national pediatric polydactyly treatment patterns is crucial for care guidelines.

Purpose of the Study:

  • To analyze national pediatric polydactyly management trends.
  • To evaluate operative and procedural patterns, timing of treatment, and associated factors.
  • To compare costs and complications of different interventions.

Main Methods:

  • Utilized the PearlDiver national administrative claims database (2010-2023).
  • Identified pediatric patients (≤18 years) diagnosed with polydactyly.
  • Analyzed surgical correction and suture ligation procedures, including costs and complications.

Main Results:

  • A decrease in polydactyly diagnosis and surgery rates observed over the decade.
  • Suture ligation rates remained stable; surgery rates declined from 12.0% (2010) to 7.3% (2020).
  • Younger age and higher comorbidity index predicted surgery; higher income correlated with lower likelihood. Surgery incurred higher costs.

Conclusions:

  • A notable decline in pediatric polydactyly incidence and surgical intervention rates was identified.
  • Findings can guide future pediatric hand care guidelines and clinical discussions.
