The indications for toe transfer after "minor" finger injuries

Area of Science:

• Reconstructive surgery
• Microsurgery
• Hand surgery

Background:

• Toe-to-hand transfer is often deemed inappropriate for minor finger injuries.
• Existing literature lacks comprehensive guidelines for selecting cases and timing interventions.
• The potential for significant functional and psychological recovery is frequently underestimated.

Purpose of the Study:

• To discuss indications for toe-to-hand transfer in finger amputations and neurocutaneous/pulp defects.
• To present a novel classification system for multidigital injuries with prognostic and decision-making value.
• To advocate for considering toe transfer even in "minor" finger injuries.

Main Methods:

• Review of indications for toe-to-hand transfer in various finger injury scenarios.
• Presentation of a proposed classification system for multidigital injuries.
• Discussion based on clinical experience and established surgical principles.

Main Results:

• Toe-to-hand transfer can provide substantial long-term benefits for hand function and patient well-being.
• A multidigital injury classification system is proposed to aid prognosis and surgical decision-making.
• Early (acute) intervention is technically easier, improves hand function, and preserves critical structures.

Conclusions:

• Toe-to-hand transfer should be considered for "minor" finger injuries, not just severe ones.
• Timely surgical intervention in the acute phase maximizes functional recovery and patient satisfaction.
• The proposed classification system can guide reconstructive surgical planning for complex finger injuries.
