Abstract
The aim of this study was to evaluate the clinical and functional outcomes of patients with large post-traumatic tibial bone defects managed by double-level bone transport using the Ilizarov technique. We retrospectively reviewed 16 patients of 39.1years (range, 16.0-65.0years). The bone defects averaged 10.9±3.8cm (range: 6.0cm-20.0cm) after radical resection and were managed by double-level bone transport. Bone and functional results were evaluated according to the ASAMI criteria. The mean duration of follow-up after frame removal was 29.5±1.8months (range, 12.0-36.0months). All patients achieved complete union in both the regenerates and the docking site and eradication of infection. The mean bone transport time was 55.6±23.7days (range, 30.0-125.0days). The mean external fixation time was 12.0±3.9months (range, 5.0-18.0months), and the mean external fixation index was 1.1±0.3months/cm (rang, 0.8-2.0months/cm). The bone results were excellent in ten patients and poor in six patients. The functional results were excellent in 12 patients and good in four patients. Double-level bone transport is a safe, reliable, and successful method for large post-traumatic tibial bone defects. Furthermore, this technique can reduce bone transport time, time in frame, and total treatment time in one stage.
