[Flat crossleg flaps in the repair of large skin, muscle and bone defect of the leg. Present indications, new techniques (author's transl)].

This is a report on a patient who suffered a large skin, muscle and bone defect of the leg following a Volkmann's ischemia. The author's indications for a flat crossleg flap are explained : extended skin defect at the anterior and inner aspect of the broken tibia or a skin defect associated to a tibial defect making a secondary bone graft necessary. Finally the authors describe an original technique of crossleg flap : this consists in a trapezoidal flap with the large side being the implantation basis.
