Vascular variations in the first dorsal metatarsal artery are common in second toe transfers. Identifying vessel location, diameter, and branching is crucial for successful surgical outcomes.

Area of Science:

  • Anatomy
  • Microsurgery
  • Vascular Surgery

Background:

  • Second toe transfer is a complex reconstructive procedure.
  • Understanding vascular anatomy is critical for successful flap survival.

Purpose of the Study:

  • To classify vascular variations of the first dorsal metatarsal artery and venous structures in second toe transfer.
  • To establish a classification system for improved surgical planning.

Main Methods:

  • Anatomical analysis of the first dorsal metatarsal artery in 304 second toe transplantations.
  • Analysis of venous structures in 200 cases.
  • Classification based on location, diameter, and branching pattern.

Main Results:

  • Arterial vascularity varied by location (superficial, intramuscular, inframuscular, absent), diameter (large, medium, small), and branching pattern (ramifying, main trunk, fine branch).

  • Venous drainage also showed distinct patterns.
  • Variations in the first dorsal metatarsal artery are prevalent.

    • Conclusions:

    • A new classification system for vascular variations in second toe transfer is proposed.
    • Vessel size and location at the toe web are key indicators for successful outcomes.
    • This classification aids in surgical planning and enhances success rates in toe transplantation.
