Chronic ulceration or recurrent ulceration of scar tissue in the pretibial area can be a major problem. The operation to be described affords a safe and satisfactory method of covering the raw area left after excision of pathological tissue in this region by bipedicled full-thickness grafts brought forward from the medial and lateral aspects of the leg. The resultant defect over the calf is covered by bringing across a free skin graft from the opposite thigh.
