What is the main advantage of an abductor digiti minimi muscle flap?

• A. Maximizes venous drainage.
• B. Excellent muscle bulk at the distal end of the muscle.
• C. Reduces donor site morbidity
• D. Enhances sensation to the plantar surface

Answer: (B)

The main advantage is the excellent muscle bulk at the distal end of the abductor digiti minimi, which provides durable, well-vascularized padding to fill plantar defects and protect weight-bearing structures. This distal bulk makes the flap particularly effective for covering plantar ulcers or soft-tissue defects in the plantar foot. While the flap benefits from reliable perfusion via the lateral plantar artery, it does not enhance plantar sensation, and donor-site morbidity is acceptable but not the defining benefit.
