Toe-to-thumb transplantation in the rat

Area of Science:

• Microsurgery
• Reconstructive Surgery
• Animal Models

Background:

• Toe-to-hand transplantation is a complex reconstructive procedure.
• Challenges exist in microsurgical techniques for small tissue replantation.
• Pediatric reconstructive surgery requires specialized, delicate approaches.

Purpose of the Study:

• To demonstrate the feasibility of toe transplantation in a rat model.
• To refine microsurgical techniques for vessel and nerve anastomosis in small extremities.
• To establish a preclinical model for improving human toe-to-hand transplantation outcomes.

Main Methods:

• Harvesting a toe from the hind foot of a rat.
• Transplanting the toe to the thumb position in the same rat.
• Performing microvascular and nerve anastomoses to ensure viability.

Main Results:

• Successful transplantation of the rat toe to the thumb position.
• Demonstrated viability of the transplanted digit through established vessel and nerve connections.
• The procedure was performed with notable ease and confidence.

Conclusions:

• Rat toe transplantation is a viable preclinical model for hand and small tissue replantation.
• Mastery of this technique can lead to increased success in human toe-to-hand transplants.
• This method holds promise for improving reconstructive surgery outcomes, especially in pediatric cases and complex replantations.
