Author information: (1)Department of Orthopedics and Traumatology, Assiut University Hospital, Assiut, Egypt. This article reports the treatment of massive tibial bone defects by bone transport using the Ilizarov external fixator. Fifteen patients were treated using this technique (3 females and 12 males). The defect size ranged between 7 and 22 cm (average: 10.6 cm). Etiology was infected nonunion in 9 patients, nonunion in 5 patients, and recurrent giant-cell tumor in 1 patient. The affected site was the tibial diaphysis in 10 patients, the lower tibial metaphysis in 4, and the upper tibial epiphysis in 1 patient. The external fixation time ranged from 9 months to 17 months (average: 12.27 months). External fixation index ranged from 21.8 to 42.5 day/cm (average: 35.7 day/cm). There was no recurrence of infection, no recurrence of the tumor, nor fractures after frame removal. We had to graft the docking site in 2 patients for delayed union and 2 patients developed equinus deformity and had tenoplasty for the Achilles tendon at the time of frame removal. Four patients had pin tract infection at > or =1 of the wires and this was successfully treated by antibiotic injection at the wire site. This study suggests that Ilizarov bone transport is a reliable method to fill massive bone defects. DOI: 10.3928/01477447-20060101-10
