Management of infected gap non-union of the femur using the Ilizarov technique: a clinical review

Introduction: Infected gap non-union of the femur is a challenging condition, often requiring advanced treatment methods. The Ilizarov technique, using distraction osteogenesis, is an effective solution, promoting bone healing, deformity correction, and limb length restoration without bone grafting. Materials and methods: Between 1990 and 2023, 145 patients with infected femoral non-unions were treated with the Ilizarov technique. Bone transport was used for defects ranging from 2.5 to 27 cm, with no bone grafts. Treat ment outcomes were evaluated based on healing, infection control, and functional recovery. Results: All patients achieved union, with 5 requiring reapplication of the Ilizarov fixator. The average treatment time was 8.5 months, with patients able to bear weight during recovery. Discussion: The Ilizarov technique proved highly effective in managing infected femoral non-unions, offering superior outcomes over traditional methods and enabling functional recovery with minimal complications. Conclusion: The Ilizarov technique is a safe, effective treatment for infected femoral non-unions, achieving successful healing and functional restoration without bone grafting.1,2
