Bone transport in post traumatic segmental defect,including infected nonunion using simple AO fixator with threaded Rod

We report our experience of the using ao fixator for bone transport in 10 patients with segmental bone loss,chronic osteotomylitis after trauma 3 cases with femoral shaft fracture,8 cases with tibial fracture.the mean age of the patients was 32 year(20-50).most of the patient had open fracture iiia. all patients were initially managed somewhere else. six were initially treated with external fixator 4 had im. nailing. all patients were anaemic with raised tlc count. culture swabs were positive for staphylococcus,and e coli.im nails were removed necrotic segments were excised. with frequent debridements they were made culture negative. the direction of transport proximal to distal. the mean bone defect 9.36. in femoral case it was 8.5 cm. the mean duration of transport was 14.5 months. 11-19 months. the total duration from application to removal of fixator was 11-24 months. there was no deep infection.refracture.in 4 patients 60% had bone grafting of docking site. the common complication was pin tract infection which was managed accordingly..
