    Journal: Clin Orthop Relat Res; 1992 Jul; (280):143-52. PubMed ID: 1611734.
    Abstract:
    Circular external fixation using the Ilizarov apparatus combined with internal bone transport or compression-distraction techniques were used to treat 28 patients with infected nonunions or segmental bone loss of the tibia. There were 22 males and six females with an average age of 34 years (range, 17-58 years). Six of 28 patients had infected tibial nonunions associated with hemicircumferential bone loss. These tibiae were treated by anterior hemicircumferential corticotomy and partial bone fragment internal transport. Fifteen of the remaining 22 patients had an average of 4 cm of segmental bone loss (range, 2-7 cm). Seven patients without shortening or defect had infected nonunions associated with extensive diaphyseal sequestrae. These nonunions were treated by en bloc resection of the diaphyseal shaft and internal bone transport. All patients healed their infected extremities without the addition of cancellous bone graft, microvascular fibular, or soft-tissue grafting. Preoperative shortening was present in 13 of 28 patients. Regenerate new bone formation averaged 6 cm (range, 1.5-22 cm). Postoperative antibiotics were not administered in 21 of 28 patients. In seven patients, antibiotics were given for ten days after en bloc resection of the diaphyseal sequestrae. Equal limb length was maintained in 21 extremities, within 1 cm in five tibiae and less than 3 cm in two tibiae. Functional results were good to excellent in 21, fair in six, and poor in one. The application of Ilizarov techniques to diaphyseal infected nonunions and segmental defects is very encouraging. It may prove to be an excellent technique for future management of resistant diaphyseal infections of bone.
