Abstract
Trephanation (Drilling holes into the marrow cavity) is a valuable method for promoting granulation tissue to support a skin graft. We herein report a 71-year-old Japanese male who suffered 3rd degree burns over 25% of his body and 2nd degree burns over 5% of his body on the face and limbs due to a forest fire. The fronts of the bilateral lower legs were burned deeply and the anterior tibia muscle was fallen into necrosis. The bilateral tibias which were exposed by debridement were treated by trephanation to stimulate the formation of granulation tissue. The granulation tissue formation achieved by trephanation was found to be useful for burn patients with a small degree of bone exposure.
