Treatment of infected forearm nonunion and defects represents a difficult task for the operating sur-geons. Conventional methods like composite and vascularized fibular grafts and the induced membranes filled with cancellous autografts or the Masquelet technique have been reported to be useful and suc-cessful, but sometimes it is difficult to predict the outcome and cannot address simultaneous deformities or the need to apply gradual distraction for reduction of a chronically dislocated radial head. Ilizarov technique has an answer for such conditions. We report a 43 years old man with infected ulnar defect and dislocated radial head as a result of infected Monteggia fracture: the patient was successfully treated by Ilizarov bone transport after failed attempts by bone spacer and fibular graft.
