Congenital trigger digits, often presenting after infancy, require surgical release of the A1 pulley for excellent outcomes in most cases. Trigger thumbs are more common and do not resolve spontaneously, unlike some trigger fingers.

Area of Science:

  • Pediatric Orthopedics
  • Hand Surgery
  • Congenital Hand Anomalies

Background:

  • Congenital trigger digit is a condition affecting newborns and children.
  • Presentation typically occurs after the neonatal period, not exclusively in infancy.
  • Distinctions exist in presentation and natural history between trigger thumbs and trigger fingers.

Purpose of the Study:

  • To review cases of congenital trigger digits.
  • To analyze differences between trigger thumbs and trigger fingers.
  • To evaluate the outcomes of surgical intervention.

Main Methods:

  • Retrospective review of 41 patients with 57 congenital trigger digits.
  • Analysis of patient age at presentation.
  • Documentation of spontaneous resolution and surgical treatment outcomes.

Main Results:

  • Thumbs were more frequently affected (57 digits in 41 patients).
  • Ten cases involved bilateral trigger thumbs; none resolved spontaneously.
  • Two trigger fingers resolved without surgery, while others required intervention.
  • All 39 surgically treated children had excellent results after A1 pulley release.

Conclusions:

  • Congenital trigger digits, particularly thumbs, often necessitate surgical release of the A1 pulley.
  • Surgical intervention yields excellent outcomes for affected children.
  • Understanding the differences between trigger thumbs and fingers is crucial for management.
