Aim of the study was to evaluate the results of the patients with "congenital pseudartrosis of tibia" treated by vascularized fibular graft transferred from the contralateral calf. METHODS The cohort consist of four patients (2 boys and 2 girls) aged 5.75 y (range 4-8 years) in the time of the transfer of vascularized fibular graft from the contralateral calf into the resected tibia suffered from pseudarthrosis Crawford type II, III and IV. Patients were operated on between 1999-2007. RESULTS A total graft union was achieved in three patients in one-year follow-up period. In one girl, treatment failed due to infection and was treated later with intramedullar Rush nail fixation and additional spongioplasty with an unsatisfactory result. CONCLUSIONS Authors believe that after an accurate preoperative planning in cooperation with the microsurgeon, the treatment of congenital pseudarthrosis of the tibia by vascullarized fibular graft should be considered as a very effective, accurate and relatively safe method (Tab. 2, Fig. 4, Ref. 7).
