Ten year experience with use of Ilizarov bone transport for tibial defects.

摘要

Tibial defects greater than 4 cm and secondary to high-energy trauma or debridement for infected nonunion pose a significant challenge to the treating orthopaedic surgeon. Twelve patients who had been treated with Ilizarov bone transport for tibial defects over the past ten years were retrospectively reviewed. All patients were male with an average age of thirty-two. Ten of the twelve limbs were categorized as Grade IIIB fractures initially. The average tibial defect at initiation of bone transport was 9.45 cm (range 4 to 20 cm). The mean external fixator time (EFT) was 16.7 months with a mean external fixator index (EFI) of 2.0 months per centimeter. There were a total of 36 complications. Twenty were minor, fourteen were major without sequelae and two were major with sequelae. Overall bone results were good or excellent in nine patients. Overall functional results were good or excellent in eight patients. Ten patients achieved union after Ilizarov bone transport. Use of Ilizarov bone transport can bean effective tool for treating large tibial defects. However, the treatment time is lengthy with a considerable risk of complications.
