Foot and ankle soft-tissue deficiencies: who needs a flap?

Area of Science:

• Reconstructive Surgery
• Orthopedic Surgery
• Plastic Surgery

Background:

• Soft tissue defects in the foot and ankle often require surgical reconstruction.
• Skin grafts may be insufficient for full-thickness loss, particularly over weight-bearing or prominent bony areas.
• Flap surgery offers a robust solution for complex integumentary defects.

Purpose of the Study:

• To outline the indications for flap use in foot and ankle soft tissue reconstruction.
• To describe specific flap techniques commonly employed for various foot and ankle regions.
• To provide guidance on selecting appropriate flaps based on defect characteristics and location.

Main Methods:

• Review of common flap procedures for foot and ankle soft tissue deficits.
• Categorization of flap choices based on anatomical location (metatarsal, hindfoot, Achilles, dorsum, calcaneus).
• Discussion of flap selection criteria, including defect depth and vascularity.

Main Results:

• V-Y advancement flaps are frequently used for metatarsal defects.
• Free-tissue transfer is indicated for hindfoot reconstruction.
• Sural flaps are suitable for the Achilles region.
• Muscle flaps are preferred for the dorsum of the foot and calcaneal defects.
• Thin skin flaps (e.g., radial forearm) are utilized for small lesions with good vascular inflow.

Conclusions:

• Flap selection for foot and ankle soft tissue reconstruction depends on the specific anatomical location and nature of the defect.
• V-Y advancement, free-tissue transfer, sural, and muscle flaps represent key reconstructive options.
• Appropriate flap choice is essential for successful coverage and functional restoration of the foot and ankle.
