the management of problems in lower extremity salvage using shortening lengthening technique and free flaps a case report

High-energy trauma leads to the increasing number of patients with severe leg injuries, often resulting in severe comminuted bone fractures with large area of soft tissue defects and vascular, nerve and muscle injuries. In the 1950s, Ilizarov technique was applied to the treatment of large tibial defect with bone transplantation and bone lengthening techniques. In recent years, shortening-lengthening technique was also used in the second stage. One case of complex lower extremity injury was also treated by shortening-lengthening technique combined with free flap transplantation. The problems in the process were managed properly. The clinical effect was good and the patients were satisfied. The report is as follows.
