Management of infected nonunion of tibia by Ilizarov technique

Abstract

Purpose: The purpose of this study is to assess the outcome of debridement and Ilizarov ring fixator (IRF) in the management of infected nonunion of tibia. Materials and Methods: Sixteen patients with infected nonunions of the tibia were managed by debridement and resection of infected portion and stabilization by IRF. In six patients shortening was 2.5 cm managed by corticotomy and distraction osteogenesis. The results were analyzed radiologically, skeletal, and functional results using Association for the Study and Application of Methods of Ilizarov (ASAMI) scoring system. Results: All fractures united and infection eradicated completely. According to ASAMI classification, bone results were excellent in 9, good in 5, fair in 2, and no poor. Functional results were excellent in 9, good in 5, fair in 2, and no poor. The most common complication was pin site infection. Out of 16 patients, 10 had Grade II, 4 had Grade III, and 2 had Grade IV infection which was managed accordingly. There were no major complications or neurovascular complications. Conclusion: We conclude that for management of infected nonunion of tibia, radical debridement with IRF give satisfactory bone results and functional results. Thus, Ilizarov technique is a most versatile and promising technique in the management of infected nonunion of tibia.
