[Treatment of a necrotizing soft tissue infection].

The surgical procedure for the life-threatening course of a necrotizing soft tissue infection of the leg after minor trauma is described. The necessary consistent resection of extensive fascial and muscular necroses required the reconstruction of soft tissue defects of the knee, the ankle joint and peroneal tendons exposed over a long distance. The functional outcome is presented 1 year after use of MatriDerm® and a split-thickness skin graft for defect coverage.
