title: Forefoot reconstruction by reversed island flaps in diabetic patients.
abstract: Soft-tissue coverage of the foot is often difficult, especially when the distal third of the foot (dorsal or plantar aspects) is involved. The clinical situation can be further complicated when diabetic patients are affected by painful and unstable wounds of this kind because of the familiar phenomenon of vasculopathy. The purpose of this study was to evaluate the possibility of using distally based foot flaps to cover forefoot defects in diabetic patients. Preoperative selection of patients was the key to this study; those who had other major disease, chronic infection, bone involvement, and/or insufficient foot vascularization were excluded from the study. The authors report a series of 12 diabetic patients in whom the reconstruction of medium-sized defects (ranging from 1.5 x 2.0 cm to 3.0 x 7.0 cm) of the forefoot was performed using distally based dorsalis pedis flaps or medial plantar flaps. The transferred flaps survived and adapted well to the defects, except for one flap in a patient who had a slight venous insufficiency at outset. Wearing their own footwear, patients could walk after 20 to 30 days. After the follow-up period (3 months to 3 years), no skin breakdown in the treated areas was observed. Temporary donor-site pain was reported by medial plantar flap patients, and partial skin graft loss at the donor site occurred in some of the dorsalis pedis patients. The authors suggest that in selected cases, medium-sized soft-tissue defects involving the dorsal aspects or the weight-bearing areas of the diabetic foot can be successfully covered with distally based island flaps.
