Outcomes of Ilizarov Ring Fixator in Infected Nonunion of Tibia

Objective: This study was designed to evaluate the effectiveness of Ilizarov. We aimed to explore the infection rate, bony union, and functional outcomes of Ilizarov fixators.

Methodology: This retrospective study was conducted in Orthopedic department of Bolan Medical Complex Hospital Quetta Pakistan from June 2020 to June 2021. In this timeframe total of fifty-five patients of infected nonunion tibia were enrolled for Ilizarov technique treatment. For surgical intervention, patients were placed in a supine position on a radiolucent table. Ilizarov fixator was prepared on the behalf of patient's limb length, infection site, and ankle and knee functional status. We applied assembled Ilizarov fixator at the tibial shaft while keeping in mind that the rings were positioned in on the proximal and distal fragments. The ring was placed parallel to the joints whereas pins were inserted perpendicular to the tibial mechanical axis.

Results: A total of 55 patients were recruited for this study. The mean age of the selected participants was 45.65±16.69 years. The overall successful bone results of the ASAMI score were observed as 80% whereas 88% functional outcomes were achieved. In bone results, we observed 28 (50.9%) cases with excellent results, 16 (29%) with good, 7 (12.7%) with fair, and 3 (5.4%) with poor outcomes. On the other hand, 25 (45.4%) cases observed excellent functional results, 25 (45.4%) with good, 4 (7.6%) with fair, and 2 (3.6%) with poor outcomes.

Conclusion: Our results show a high success ratio therefore we recommend Ilizarov external fixators for infected nonunion tibial fracture. This method helps to recover limbs without any amputations. However, the discomfort of patients is one of the main problems with this method of treatment.
