Island flaps successfully reconstructed finger pulp defects using reversed digital vessels. This technique is effective for non-dominant middle, ring, and little fingers, prioritizing function over sensation.

Area of Science:

  • Hand surgery
  • Microsurgery
  • Plastic surgery

Background:

  • Reconstruction of distal phalanx and digital pulp defects presents a surgical challenge.
  • Island flaps offer a potential solution for soft tissue defects in the hand.

Observation:

  • Seven cases involving eight fingers with distal phalanx amputation and pulp defects were treated.
  • The study utilized island flaps with digital vessels as reverse vascular pedicles for reconstruction.

Findings:

  • All island flaps demonstrated successful survival and vascularization.
  • Vascular supply was derived from the digital palmar arch, an anastomosis between radial and ulnar digital arteries.
  • The technique uses a single operative field and restores volar skin with similar qualities.

Implications:

  • This method is a viable option for finger pulp reconstruction, particularly when preserving volar skin characteristics is desired.
  • Limitations in sensory recovery restrict its application to the middle, ring, and little fingers of the non-dominant hand.
  • Further research may explore methods to improve sensory outcomes in island flap reconstructions.
