Summary

Congenital trigger digits, often presenting after the neonatal period, show distinct patterns in thumbs versus fingers. Surgical release of the A1 pulley yields excellent outcomes for persistent cases.

Area of Science:

  • Pediatric Orthopedics
  • Hand Surgery
  • Congenital Hand Differences

Background:

  • Congenital trigger digits are a common hand anomaly in children.
  • Most cases present beyond the neonatal period, contrary to common assumptions.
  • Distinguishing between trigger thumbs and trigger fingers is crucial for understanding presentation and prognosis.

Purpose of the Study:

  • To analyze the clinical presentation and outcomes of congenital trigger digits.
  • To compare the characteristics of congenital trigger thumbs and trigger fingers.
  • To evaluate the efficacy of surgical intervention for congenital trigger digits.

Main Methods:

  • Retrospective review of 53 patients with 70 congenital trigger digits.
  • Analysis of patient demographics, affected digits, bilaterality, and spontaneous resolution.

  • Assessment of treatment outcomes, including surgical release of the A1 pulley.

    • Main Results:

    • Thumbs were more frequently affected than fingers (30% bilateral).
    • Congenital trigger thumbs did not resolve spontaneously, unlike some trigger fingers (28% resolved spontaneously).
    • Surgical release of the A1 pulley resulted in excellent outcomes for all treated patients.

    Conclusions:

    • Congenital trigger digits exhibit different characteristics based on location (thumb vs. finger).
    • Early presentation is less common; most cases manifest later.
    • Surgical management provides effective treatment for persistent congenital trigger digits.
