The cross thumb to index finger pedicle

Area of Science:

• Plastic surgery
• Hand surgery
• Reconstructive surgery

Background:

• Index fingertip amputations can expose bone.
• Nailbed avulsions present reconstructive challenges.

Purpose of the Study:

• To describe a surgical technique using the thumb dorsum as a donor site.
• To evaluate the efficacy of this flap for fingertip reconstruction.

Main Methods:

• Utilizing an oblique, radially based flap from the proximal phalanx of the thumb.
• Grafting the flap to cover exposed bone in index fingertip amputations.
• Applying the flap for nailbed avulsion coverage in select cases.

Main Results:

• Successful coverage of exposed bone in index fingertip amputations.
• Effective reconstruction for certain nailbed avulsions.

Conclusions:

• The thumb dorsum provides a viable donor area for index fingertip reconstruction.
• This technique offers a solution for exposed bone and nailbed defects.
