Area of Science:

  • Plastic Surgery
  • Hand Surgery
  • Microsurgery

Background:

  • Reconstruction of digital defects, particularly the tactile pad, remains a challenge in hand surgery.
  • Previous techniques often involve multiple stages or compromise sensation.

Purpose of the Study:

  • To describe a new technique for creating a homodigital island flap with a reverse vascular pedicle.
  • To evaluate the efficacy of this flap for reconstructing tactile pad defects in the hand.

Main Methods:

  • A homodigital island flap with a reverse vascular pedicle was designed, utilizing anastomoses between radial and ulnar digital arteries.
  • The flap incorporated the digital nerve and was transferred to cover defects in 11 patients.
  • Vascularization was achieved via the middle transverse palmar arch.

Main Results:

  • The technique successfully provided well-vascularized skin cover for tactile pad defects in all 11 patients.
  • Early mobilization was possible in all cases, with follow-up ranging from 7 to 43 months.
  • The flap provided good quality skin cover, preserving tactile sensation.

Conclusions:

  • The reverse vascular pedicle homodigital island flap is an effective one-stage procedure for tactile pad reconstruction.
  • Despite digital nerve and artery division, the benefits of well-vascularized, sensate skin cover and early mobilization outweigh the drawbacks.
