Technical considerations for replantation: from bony fixation to soft tissue coverage

Area of Science:

• Microsurgery
• Hand Surgery
• Reconstructive Surgery

Background:

• Digital replantation presents significant surgical challenges.
• Success hinges on meticulous technique and appropriate patient selection.
• Zone II flexor tendon injuries require specific repair strategies.

Purpose of the Study:

• To outline technical considerations for digital replantation.
• To detail the optimal sequence for structure-by-structure repair in zone II.
• To address special circumstances including thumb, multiple digit, and heterotopic replantation.

Main Methods:

• Systematic review of technical aspects for digital replantation.
• Emphasis on a sequential, structure-by-structure repair approach.
• Description of modifications for thumb, multiple digits, and heterotopic replantation.

Main Results:

• A structured approach to digital replantation, particularly for flexor tendon zone II, enhances reliability.
• The recommended repair sequence optimizes outcomes in non-thumb digits.
• Specific adaptations are necessary for complex cases like thumb or multiple digit replantation.

Conclusions:

• Digital replantation is a viable and rewarding procedure when executed with careful planning.
• Adherence to a systematic repair sequence, especially in zone II, is crucial for success.
• Specialized techniques are essential for managing thumb, multiple digit, and heterotopic replantations.
