A clinical study of Ilizarov technique in infected non union of fracture shaft of tibia

Abstract

Background and Objectives: Infected non-union is a chronic and debilitating disorder that still poses a very complex problem to the surgeon today in terms of cost and time-effective treatment. Application of the Ilizarov frame to treat complex tibial non-union has become an established orthopaedic procedure. The results in achieving union and eradicating infection are well documented. The purpose of the study is to assess the role of Ilizarov's technique in infected nonunion in minimizing the morbidity and to gain a deeper understanding of the results and problems associated with this technique. Methods: The present study was a prospective study of 22 patients with infected nonunion shaft of tibia satisfying the inclusion criteria admitted in KIMS, Hubli between the study period of November 2007 to October 2008. Cases were selected according to inclusion criteria. Results: In our series of 22 cases, there were 21 males and 1 female, with a maximum age of 72 years, minimum age of 19 years and the mean age of 34.5 years. In most of our cases, mode of injury was Road traffic accident (75%). Most patients (59%) were having Draining type of Nonunion. Bony results were excellent in 72.72% of cases, good in 18.18% and fair in 4.5% of cases. Functional results were excellent 82% of cases, good in 9% and in 9% poor. Conclusion: Ilizarov technique, despite few unfavourable results and complications, after clearing infection and resection of sequestrated bone, it not only allowed repair of defect but also restoration of activity and limb length. It gave satisfactory results in treatment of infected nonunion of shaft tibia. Joint function and weight bearing while on treatment, is an advantage which cannot be matched by any other technique.
