- PURPOSE
To study clinical results and complications in the treatment of infected nonunion of the tibia according to location of nonunion and reconstruction for soft tissue defect.
MATERIALS AND METHODS
36 cases of tibia infected nonunion which were treated with the llizarov included in this study. There were proximal 1/3 in 14, middle 1/3 in 10, and distal 1/3 in 11 cases. Coverage of the soft tissue were treated with the free flap in 8 cases as classified group A and non-free flap in 17 cases classified group B. We evaluated the healing index, complications and comparing the results of each treatment by the Paley method.
RESULTS
Bone union was achieved in all cases. The proximal nonunion showed better results than those in the middle and distal area; average healing index: 35.6 days/cm (p=0.038), bone results: 92.9% (p=0.025), functional result: 90.5% (p=0.03). Group B showed significantly better results as it showed average healing index: 30.3 days/cm (p=0.015), bone results: 85.7% (p=0.025), functional results: 90.5% (p=0.015).
CONCLUSION
The nonunion of proximal 1/3 showed better results than other sites. Soft tissue reconstruction with free flap that control infection more effectively, could be improved the treatment outcomes.
