The purpose of the present study is to review the author's interim results of Ilizarov technique performed in twelve consecutive patients with congenital pseudarthrosis of the tibia. There were eight boys and four girls. Their age ranged from ten months to thirteen years and five months, averaging five years and five months. Ilizarov device was applied for union of pseudarthrosis in six patients, for union of pseudarthrosis and simultaneous leg lengthening in two, and for leg lengthening and deformity correction in four. Follow-up periods averaged 2.0 years, ranging from 1,3 years to 3.3 years. Union was obtained in all eight patients with frank pseudarthrosis. The length gain averaged 3.5 cm, ranging from 0.5 cm to 7.5 cm. The healing index averaged 2.1 months/cm, ranging from 1.0 to 4.0 months/cm. The angular deformity correction obtained averaged 23 degrees, ranging from 10 to 48 degrees. In conclusion, we believe that Ilizarov method for treatment of congenital pseudarthrosis of the tibia is a valid procedure for osteosynthesis, correction of angular deformity, and leg lengthening.
