Objective To describe the clinical experiences of treatment for lower limb deformity in children by Ilizarov technique. Methods 31 cases were treated by Ilizarov technique, among which are 2 pseudarthrosis with the history of failed bone grafting and internal fixation, 4 bone ununion due to osteomyelities, 4 shortened after osteoplasty. 11 discrepancy of lower limbs, 8 congenital talipes equinovarus and 1 case of achondroplastic dwarf. Results Expected correction were achieved in all the cases. Conclusion Bone defect and associated discrepancy of extremities can be treated simultaneously by Ilizarov technique. Pseudoarthrosis can be removed surgically. Lengthening and compression can be done simulteneously. Ilizarov stable fixation can be used to treat congenital talipes equinovarus. Achondroplastic dwarfs can be treated by bilateral lengthening of the lower limbs.
