Study of Functional Outcomes of the Ilizarov External Fixator in the Treatment of Open Tibial Fractures (Gustilo-Anderson Grades II, IIIA, and IIIB): A Prospective Clinical Study

Introduction: Open fractures of the tibia are commonly associated with significant soft tissue injury and high risk of complications, posing a challenge in achieving optimal functional outcomes. The Ilizarov external fixator offers stable fixation with minimal soft tissue disruption and allows early mobilization. The present study aimed to evaluate the functional outcomes of the Ilizarov external fixator in the management of open tibial fractures (Gustilo-Anderson grades II, IIIA, and IIIB). Materials and methods: This prospective observational study was conducted in the Department of Orthopaedics at Shri B. M. Patil Medical College, Hospital and Research Centre, Vijayapura, Karnataka. A total of 20 patients aged 18-65 years with open tibial fractures were included. All patients underwent initial surgical debridement, following which fractures were classified according to the Gustilo-Anderson classification and subsequently managed with Ilizarov external fixation. Clinical, radiological, and functional parameters were assessed during follow-up. Functional outcome was evaluated using the Johner and Wruhs criteria, a fracture-specific scoring system incorporating clinical, radiological, and functional parameters. Results: Among 20 patients, the majority were males (17 (85.0%)) and in the age group of 20-40 years (15 (75.0%)). Road traffic accidents were the most common mode of injury (15 (75.0%)). Grade IIIB fractures were predominant (10 (50.0%)), and distal third fractures were most common (12 (60.0%)). Early fixation within 24 hours was achieved in 17 (85.0%) patients. Bone loss was present in seven (35.0%) patients, and corticotomy was performed in six (30.0%). Pin tract infection occurred in 11 (55.0%) patients, predominantly grade II (8 (40.0%)), with no deep infections (0 (0.0%)). All patients achieved fracture union (20 (100.0%)) with satisfactory functional outcomes; excellent to good results were observed in 18 (90.0%) patients. Early weight bearing was achieved in all patients (20 (100.0%)). Conclusion: The Ilizarov external fixator is an effective modality for the management of open tibial fractures, providing stable fixation, early mobilization, and satisfactory functional outcomes. However, findings should be interpreted cautiously, and further large-scale studies are required to validate these results.
