Reversed First Dorsal Metatarsal Artery Island Flap for First Ray Defects

Area of Science:

• Orthopedic Surgery
• Plastic Surgery
• Reconstructive Microsurgery

Background:

• Reconstruction of the first ray presents significant challenges, including poor skin laxity, exposed bone and tendons, and limited local flap availability.
• Standard reconstructive methods like skin grafts are often unsuitable due to exposed structures.
• Existing local flap options from the distal foot are frequently restricted by insufficient soft tissue coverage.

Observation:

• This study presents two clinical cases detailing the successful reconstruction of great toe and first ray defects.
• The primary reconstructive technique employed was the reversed first dorsal metatarsal artery island flap.
• Anatomical studies were conducted to evaluate the flap's suitability for distal foot reconstruction.

Findings:

• The reversed first dorsal metatarsal artery island flap proved to be a suitable alternative for soft tissue defects of the distal foot.
• This flap is particularly effective for first and second ray defects.
• Key advantages include its thin, simple nature, anatomical similarity to recipient sites, and minimal donor site morbidity.

Implications:

• The reversed first dorsal metatarsal artery island flap expands reconstructive options for complex foot defects.
• This technique offers a reliable method for restoring form and function in the distal foot.
• Further adoption of this flap could improve outcomes for patients with first ray injuries.
