Functional and radiological evaluation of treatment of infected nonunited fracture shaft femur using Ilizarov external fixator

Background
The treatment of infected nonunion of long bones has always been a challenge for orthopedic surgeons. Treatment goals were eradication of infection and bony union. During distraction osteogenesis, physiological bone loading and mobilization are very important.
Aim
This study aimed at evaluating the functional and radiological outcome of using Ilizarov external fixator in treating patients with infected nonunited fracture femoral shaft.
Patients and methods
Fifteen patients with infected nonunion of the shaft of the femur were included in the study between 2007 and 2009. The mean age of the patients was 39.5 years (range 19–68 years). The follow-up period lasted for 14–36 months with a mean of 25.7 months. Bone and functional results were measured and complications were categorized according to the Association for the Study and Application of the Method of Ilizarov guidelines.
Results
The infection was eradicated in 12 patients before the fixator removal. Excellent radiological bone healing was found in 12 patients, and excellent functional result in eight out of 15 patients. There were a total of 20 complications in 15 patients.
Conclusion
Ilizarov external fixator is an effective method for the treatment of infected nonunited fracture shaft femur with acceptable radiological and functional outcome and low serious complications.
