Pediatric Trigger Digits

Area of Science:

• Pediatric Orthopedics
• Hand Surgery

Background:

• Pediatric trigger thumb is a common condition presenting in early childhood, characterized by thumb interphalangeal joint flexion.
• It is primarily attributed to a developmental size discrepancy between the flexor pollicis longus tendon and its surrounding sheath.

Purpose of the Study:

• To review the current understanding and treatment approaches for pediatric trigger thumb and other pediatric trigger digits.
• To discuss the efficacy of surgical versus non-surgical interventions.

Main Methods:

• Review of existing surgical literature on A1 pulley release for trigger thumb.
• Analysis of recent reports on non-surgical management and spontaneous resolution.
• Examination of etiologies and treatment strategies for trigger digits other than the thumb in children.

Main Results:

• Open A1 pulley release surgery demonstrates near-universal excellent outcomes for pediatric trigger thumb.
• Non-surgical treatment may lead to spontaneous resolution over several years but requires significant parental patience.
• Triggering in other pediatric digits often indicates underlying conditions requiring more extensive surgical intervention, potentially including A3 pulley release and flexor digitorum superficialis tendon resection.

Conclusions:

• Surgical A1 pulley release remains the gold standard with high success rates for pediatric trigger thumb.
• Non-surgical observation is a viable option for select families, acknowledging the potential for delayed spontaneous resolution.
• Triggering in pediatric digits other than the thumb necessitates thorough investigation for underlying pathologies and often requires tailored surgical management beyond simple pulley release.
