ABSTRACT
In this study, the results of the use of Ilizarov method of bone transport to overcome the bone defect of forearm bones were reported. The study included 16 patients with bone defect of forearm bones either posttraumatic or following debridement of osteomylitis or infected nonunion. The mean time from injury to the Ilizarov procedure was 11.7 months. The mean operative procedures before the application of the Ilizarov device was 3.4. The mean length of the defects after debridement was 6.4 cm. The Ilizarov circular external-fixator construct was used. Mono-focal osteotomy was performed. Distraction begun approximately at seven days after the operation at 0.25 mm four times daily. The results were evaluated clinically using the external fixation index, the distraction index and the maturation index. The roentgenographic quality of the regenerated bone was evaluated with the criteria of Catagni [1998]. The mean external fixation index, distraction index and maturation index were 41.5 days/cm, 19.8 days/cm and 21.7 days/cm, respectively. The mean time in the frame was 8.9 months. The mean total duration of treatment including the fixator and cast duration was 11.4 months. There were 14 complications in 11 patients including pin track infection, premature consolidation, delayed union at the docking site and refracture. There were varying degrees of limitation of pronation and supination in all patients
