what is a skin flap
Wound located on the limbs may be reconstructed with skin flaps. Skin flaps are somewhat more resilient than skin grafts. Definition of a skin flap. A skin flap is a piece of skin that has its own blood supply (i.e. still attached to the body by a major artery and vein or at its base) and placed on a wound. Because this type of flap has its own blood supply it is much more resistant to external factors such as movement, fluid accumulation beneath the flap, and infection.
