    Abstract:
    Massive bone defects have been treated by various methods with variable success rates. The Ilizarov technique has been advocated as a preferred method for treatment of large segmental defects. Twenty five patients with massive post traumatic bone defects of the lower limb (22 tibiae, 3 femurs) were treated using Ilizarov's technique. After radiological evaluation, the patients were subjected to bone transport. Bifocal osteosynthesis was performed in all except those needing >12 cm of bone transport. Distraction was started between day 4 and 7 at the rate of 1 mm per day in four increments. All were males with a mean gap of 8.9 cm (range: 5-17 cm), mean age of 28.24 years (16-40) and having undergone a mean of 2.6 previous surgeries. Mean time in Ilizarov frame was 8.8 months and external fixator index was 0.98 months. Mean duration of follow-up after frame removal was 23.5 months. Union was achieved in 23 (92%) cases. Bone grafting was required in 9 (36%) According to ASAMI criteria, bone results were excellent in 13, good in 1, and poor in 11 patients. Functional results were excellent in 6 patients, good in 9, fair in 4, and poor in 6 patients. A total of 72 complications occurred (2.88 complications per patient). Union was achieved in all except two patients. The Ilizarov external fixator offers a limb salvage solution even in large bone defects but the surgeon should set realistic goals both for himself and his patients while offering this method of treatment.
