We reviewed thrity-one cases of unstable tibial fractures treated with Ilizarov method from January 1991 to December 1992. We attained satisfactory bony union in all cases without bone graft(Average time 19.2 weeks). There were numbers of complications, 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 was 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.
