We reviewed fifteen cases of unstable tibial fractures treated with Ilizarov method from May 1995 to May 1996. We attained satisfactory bony union in all cases without bone graft(Average time 19 weeks). There were numbers of complications, such as pin tract infection, angular deformity and joint ankylosis but its were soluble and careful management & numbers of minor surgery were needed to prevent & solve such complications. Post-op immediate weight bearing and ROM exercise were possible and showed no difficulty in getting mainteance of reduction & fracture healing, and serious joint ankylosis waa not developed. In conclusions, Ilizarov method is an excellent treatment in getting reduction, maintenance of reduction, early ambulation and fracture healing in the cases of unstable tibia fractures.
