IN FULL thickness burns involving more than 30% of the body surface, the available donor sites are often inadequate to provide the required split thickness skin to cover the defect. It is desirable to increase potential coverage from limited donor sites without decreasing the physiologic effectiveness of the skin grafts. A new technique of expanding grafts by making slits in the skin has been successfully used.
Present techniques include split thickness grafts in sheets that cover an area on the recipient site equal to the donor site. This method provides the most effective skin replacement, but is only effective in smaller burns. Pinch grafts increase the area covered from an available donor site, but the new skin surface provided is poor and often requires regrafting. This method is also inadequate for large burns as it is difficult to manage the small grafts on the recipient site. Postage stamp grafts can
