Introduction Gap non-union of tibia occurring mostly after trauma and many times complicated by infection, is a difficult problem to treat. The study aimed to assess the outcome of the three-ring construct of the Ilizarov fixator frame in the management of gap non-union of the tibia. Methods This retrospective study included 30 patients of gap non-union of tibia operated from April 2016 to March 2019 with a three-ring Ilizarov fixator frame and follow-up done till March 2021. The mean age was 39.27 (range 10–66) years. The results were assessed by the Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria. MPTA, PPTA, and LDTA after removal of the frame were also measured. Results Out of the total 30 cases, all the patients showed complete union. The Ilizarov fixator was kept for an average period of 11.43 months and the mean defect size was 7.17 (range 2–12) cm. All patients were followed up for an average period of 39.36 (range 24–54) months. According to the ASAMI score bone/radiological results, 27 were classified as excellent, 2 as good, and 1 as poor. Functionally 28 were graded as excellent and the remainder as good. The normal ranges of MPTA, LDTA & PPTA were also achieved in a majority (80%) of patients. Conclusion Our results after using only a three-ring Ilizarov fixator frame are almost equivalent to earlier studies and have advantages such as less weight, better patient compliance, superior radiographic visualization, easy mobilization, and reduced costs. Ilizarov ring fixator remains an excellent treatment modality for tibial non-union with a defect, regarding bone union, deformity correction, infection eradication, limb-length achievement, and limb function. |
