Area of Science:

  • Plastic Surgery
  • Hand Surgery
  • Reconstructive Surgery

Background:

  • Fingertip amputations are common, often resulting from avulsion or crush injuries.
  • Current treatment lacks a single standard, with various techniques available.
  • Reconstruction aims to restore function and aesthetics while minimizing complications.

Purpose of the Study:

  • To evaluate the P3 flap as a single-stage technique for fingertip defects with bone exposure.
  • To assess the aesthetic and functional outcomes of P3 flap reconstruction.
  • To determine the efficacy of the P3 flap in preventing painful scarring and preserving digital length.

Main Methods:

  • The study included 12 patients with fingertip amputations (Zone IIB or less) without replantation possibility.
  • Defects were less than 2 cm with exposed bone, treated with the P3 flap under local anesthesia.
  • Outcomes were assessed at 6 months using static two-point discrimination (2-PD) and DASH scores.

Main Results:

  • The P3 flap demonstrated a 100% success rate with no flap failures or local infections.
  • Mean healing time was 4 weeks, with an average 2-PD of 5.9 mm and DASH score of 1.1.
  • Nail deformities occurred in 3 cases of Zone IIB amputation; return to work averaged 38 days.

Conclusions:

  • The P3 flap is a reliable, single-stage technique for fingertip reconstruction, suitable for defects with bone exposure.
  • It effectively avoids painful pulp scarring and preserves digital length and nail bed.
  • The procedure offers good functional recovery and aesthetic results with minimal complications.
