[Hand injury caused by a funnel-producing machine].

Authors describe a case of severe hand injury, caused by a funnel producing equipment. In the region between the metacarpals II and III a high pressure, penetrating, mechanical and thermal injury has arisen. The secondary necrosis expanded and this made a covering with soft tissue of full value necessary. Because of the local relations and allergic complications the local and distant possibilities were narrowed. It was possible to find a final solution by the transfer of flaps from the index and III finger and supplementary plastics, using split thickness skin grafts. The result was functionally perfect, esthetically adequate.
