Ilizarov's method: a solution for infected bone loss.

We report the results of 22 infected nonunions treated by radical resection and bone transport technique according to Ilizarov with a minimal follow-up period of 2 years. This series involves four fractures of the femur diaphysis, ten at tibial level, four defects of the knee and four of the upper limb. The mean length of the bone defect was 7.7 cm. The mean time from the transport procedure to frame removal was 14.5 months. In 15 cases the docking site was reviewed to refresh the bone ends at the end of the transport procedure, of which eight had a bone graft performed. Five refractures were noticed at the docking site in the nonrevised group and one in the other group. Two of them were treated conservatively and four with a new external fixator. Consolidation was achieved in all but two nonunions at the knee level, which means a succesrate of 91%. The infection could be eradicated in all 22 patients. A revision of the docking site at the end of the bone transport procedure with or without bone grafting is recommended.
