A Case of Nonisland Pedicled Foot Fillet Flap for Below-Knee Amputation Stump Wound: Treatment Option for Compartment Syndrome after Fibular Free Flap Surgery

Despite the frequent use of the fibular free flap, there have been no reports of severe compartment syndrome of the donor leg that necessitated limb amputation. A 66-yr-old man had a fibular osseous free flap transfer from the left leg to the mandible that was complicated by postoperative compartment syndrome. An extensive chronic leg wound resulted, which was treated with multiple debridements and finally with below-knee amputation. Successful coverage of the below-knee amputation stump was accomplished with a nonisland pedicled foot fillet flap. Various foot fillet flaps may be used acutely as a free or an island pedicled flap, but dissection of the vascular pedicle may be difficult in a chronically inflamed wound because of inflammation and adhesions to surrounding tissue. The nonisland pedicled foot fillet flap may be considered as a useful option for treatment of a chronically inflamed stump wound after below-knee amputation.
