Summary
Sensory feedback for reverse digital artery (RDA) flaps is achieved by connecting digital nerves. This technique offers excellent functional and cosmetic outcomes for reconstructing finger pulp defects.
Area of Science:
- Plastic Surgery
- Microsurgery
- Hand Surgery
Background:
- Reconstructing digital pulp defects often requires restoring sensation.
- The reverse digital artery (RDA) flap is a potential reconstructive option.
Observation:
- This study details a technique to innervate the RDA flap.
- Nerves are co-opted with the flap and anastomosed to recipient nerves.
Findings:
- Three cases of finger pulp defects reconstructed with this innervated RDA flap showed favorable results.
- Successful bilateral neurorrhaphy provided sensation to the flap.
Implications:
- Innervated RDA flaps offer a viable one-stage solution for major digital pulp defects.
- This technique enhances functional and cosmetic outcomes in hand reconstruction.
