First experience with a distraction apparatus prototype (SM-fix-phalanx distractor) for phalanges lengthening
1Department of Pediatric Surgery, University Children's Hospital, Basel, Switzerland.
Summary
This study shows a new external fixator and distractor system effectively lengthens phalanges in children with traumatic amputations, improving function and appearance. Bone grafting is unnecessary due to children
Area of Science:
- Pediatric Orthopedics
- Traumatology
- Hand Surgery
Background:
- Traumatic partial phalangeal amputations in children present reconstructive challenges.
- Previous methods may require bone grafting and extensive surgical intervention.
- Developing minimally invasive techniques for pediatric hand reconstruction is crucial.
Observation:
- Seven children (aged 5-17) with 10 partially amputated phalanges were treated.
- A novel external fixator and distractor system was employed for phalanx lengthening.
- Distraction osteogenesis achieved phalanx lengthening of 3-10 mm (average 55% of remaining phalanx).
Findings:
- Significant functional and cosmetic improvements were observed, particularly in distal phalanx amputations with resulting nail dystrophy (claw nail).
- Average distraction and consolidation phases lasted 5 weeks, with aftercare ranging from 2-12 months.
- Children's robust distraction-histogenesis capability eliminated the need for bone grafting, provided the integument was intact or prepared.
Implications:
- The external fixator and distractor system is well-suited for delicate pediatric hand anatomy.
- This method offers a less invasive approach, potentially reducing complications and recovery time.
- Further research could explore long-term outcomes and broader applications in pediatric hand trauma.
