[Free vascularized bone transfer en bout de chaîne]

Area of Science:

• Orthopedics
• Microsurgery
• Regenerative Medicine

Context:

• Distal finger amputations pose reconstructive challenges.
• Conventional bone grafts often fail due to resorption or infection.
• Free vascularized bone transfer (FVBT) offers a viable solution.

Purpose:

• To evaluate the efficacy of modified wrap-around FVBT techniques.
• To explore FVBT for distal finger reconstruction, including nail deformities.
• To highlight the importance of vascularized growth cartilage transfer in pediatric cases.

Summary:

• FVBT demonstrates successful bone healing without resorption, even in sclerotic or infected tissues.
• Techniques include harvesting bone with soft tissue, nail complex, or growth cartilage.
• Modified wrap-around procedures and partial toe transfers are detailed.
• Vascularized growth cartilage transfer is crucial for maintaining phalanx growth in children.

Impact:

• FVBT provides a durable solution for complex distal finger amputations.
• This technique restores function for patients requiring fine motor skills, such as musicians.
• Pediatric patients benefit from preserved growth potential, enabling continued finger development.
