Free neurovascular cutaneous toe pulp transfer for thumb reconstruction

Area of Science:

• Plastic Surgery
• Microsurgery
• Reconstructive Surgery

Background:

• Thumb injuries often require soft tissue coverage and sensory restoration.
• Free vascularized toe pulp transfer is a reconstructive option for thumb defects.

Purpose of the Study:

• To review alternative techniques for thumb coverage.
• To detail the neurovascular anatomy of the great toe relevant to transfer.
• To describe the microvascular toe pulp transfer technique.

Main Methods:

• Review of existing literature on thumb reconstruction.
• Anatomical study of the great toe's neurovascular supply.
• Description of the surgical steps for free vascularized toe pulp transfer.

Main Results:

• The great toe pulp provides durable, sensate soft tissue coverage.
• The procedure demonstrates minimal donor site morbidity.
• Excellent functional and aesthetic outcomes are achievable.

Conclusions:

• Free vascularized toe pulp transfer is a viable, albeit demanding, option for thumb reconstruction.
• It effectively restores thumb sensibility and coverage.
• Careful patient selection and surgical technique are crucial for success.
