Repair of zone 2 flexor pollicis longus lacerations in children

Area of Science:

• Pediatric Orthopedics
• Hand Surgery
• Reconstructive Surgery

Background:

• Flexor pollicis longus tendon injuries in zone 2 are common in children.
• Successful repair is crucial for thumb function and overall hand dexterity.
• Previous studies have reported varied outcomes for pediatric tendon repairs.

Purpose of the Study:

• To evaluate the long-term functional outcomes of zone 2 flexor pollicis longus tendon repairs in children.
• To assess the effectiveness of surgical intervention using a standardized classification system.

Main Methods:

• A retrospective review of seven thumbs in six pediatric patients.
• Surgical repair of zone 2 flexor pollicis longus tendon injuries.
• Assessment of outcomes using the Buck-Gramcko et al. (1976) classification system at a mean of 43 months post-repair.

Main Results:

• Excellent results were observed in six out of seven thumbs.
• Good results were reported in one thumb.
• All reviewed cases demonstrated successful functional recovery post-repair.

Conclusions:

• Surgical repair of zone 2 flexor pollicis longus tendon injuries in children yields excellent to good outcomes.
• The Buck-Gramcko et al. classification is a reliable tool for assessing pediatric thumb tendon repair results.
• Early and effective surgical intervention is key to restoring thumb function in pediatric hand injuries.
