Outcomes of ilizarov ring fixation in infected nonunion of tibia

Abstract

Objective: The objective of this study was to determine the outcomes with the use of Ilizarov's external fixator in infected nonunion of tibia. Materials and Methods: In this single-center, retrospective study at a teaching medical institute, patients who were treated with Ilizarov's external fixator for infected nonunion of tibial fractures were assessed. Achievement of union and the Association for the Study and Application of the Method of Ilizarov (ASAMI) outcomes were assessed. Results: Between January 1995 and December 2018, a total of 20 patients identified who underwent Ilizarov's procedure. The median age was 43.5 years (range: 7–65 years). The median level of bone defect was 60 mm. In 20 cases, 18 had infected nonunion. The median consolidation time was 8 months. During the median follow-up of 2 years, 83.3% (15/18) achieved complete union. The median union time was 11 months. Pin-tract infections were observed in 33.3% (6/18) of the patients. As per ASAMI outcomes, bone results were excellent in 72.2% (13/18), good in 11.1% (2/18), and poor in 16.7% (3/18), and the function results were excellent in 50% (9/18), good in 33.3% (6/18), and poor in 16.7% (3/18). Conclusion: Ilizarov's ring fixation is a reliable and suitable method for providing excellent bone and functional results in infected nonunion of tibia.
