Application of Cross-Groin Flap for Coverage of Large Skin and Soft Tissue Defects of the Foot and Ankle in Children.

ABSTRACT

In children with large soft tissue defects of the foot and ankle, it is difficult to cover the wound completely using a local skin flap, and skin grafting of the donor area for repair causes secondary damage. Free skin flaps require good vascular anastomoses and are prone to vascular crises. The authors evaluated the effectiveness and safety of cross-inguinal flaps for the repair of large soft tissue defects of the foot and ankle in children. The records of 15 children who underwent cross-groin flap transplantation between June 2017 and June 2021 were analyzed retrospectively. All the flaps survived without infection, necrosis, or other complications. The flap shape was good, the donor area was sutured directly, and the damage was minimal. This surgical method is simple, effective, and safe and can replace microsurgery, making it suitable for use in primary-level hospitals that are not equipped for microscopic surgery.
