Insights

Second toe transfers effectively reconstruct thumb amputations in young children, offering good functional recovery and growth. This safe procedure leads to fewer complications and better long-term outcomes for pediatric patients.

Area of Science:

  • Pediatric surgery
  • Microsurgery
  • Reconstructive surgery

Background:

  • Posttraumatic thumb amputations in children under 5 are rare.
  • Limited literature exists on long-term outcomes for this demographic.
  • This study details clinical experience with second toe transfers for thumb reconstruction in young children.

Observation:

  • The study included 9 children (7 boys, 2 girls) aged 1-5 years.
  • The average age at transfer was 2.8 years, with follow-up ranging from 6 to 14 years.
  • Avulsion injuries were the most common cause of amputation (33.3%).

Findings:

  • All second toe transfers survived, achieving bone union.
  • Static 2-point discrimination averaged 5 mm, indicating good sensory recovery.
  • Transferred toes demonstrated substantial growth, enabling good prehensile pinch and grasp.

Implications:

  • Second toe transfer is a highly effective reconstructive option for pediatric thumb amputations.
  • This procedure reduces the need for secondary interventions in children.
  • Late functional recovery is achievable with a favorable safety profile and high success rate.
