title: Cross-foot island instep flap: a new use of instep skin flap for management of persistent wounds after complex plantar foot reconstruction.
abstract: When presented with an extensive soft-tissue defect involving the sole of the foot, reconstruction with free muscle flaps covered by a split-thickness skin graft is the proposed method of treatment. However, persistent graft breakdown and a chronic wound of the weight-bearing flap is a challenging problem during the late postoperative period, as experienced by the authors in their patients with high-energy-induced lower extremity injuries. The authors used the instep flap as an island cross-foot flap to manage persistent graft breakdown that involved skin-grafted muscle flaps transferred previously to the heel in 3 patients and to treat a chronic wound involving an amputation stump in 1 patient. The vascular pathology of the injured extremities indicated a cross-leg procedure instead of a free flap transfer. Pedicles were wrapped with split-thickness skin grafts and flaps were harvested superficial to the plantar fascia. Pedicles were divided during postoperative week 3, and no complications related to the operation or to immobilization have been encountered during the postoperative follow-up. During the 1-year follow-up, durable coverage, free from development of open wounds, has been achieved, and patients have expressed their satisfaction. In the case of complicated, high-velocity foot injuries, the authors suggest that this procedure be kept in mind as an alternative treatment option because it has some advantages over conventional cross-leg procedures.
