Outcome of Ilizarov assisted ankle arthrodesis

Abstract

Background: Among the various techniques used for ankle arthrodesis, Ilizarov technique has various advantages along with the potential for treating complex and failed cases.Methods: Eleven cases were undertaken for ankle arthrodesis using the Ilizarov fixator. Two rings were applied along the tibia and one at the talus/calcaneum. The articular cartilage was denuded, and dynamic compression applied. The clinical, functional and radiological outcome were evaluated. The goal was a stable fusion with a well aligned foot.Results: The mean follow-up period was 95 weeks. Fusion was achieved in all cases with no major complication. Only one case had a residual deformity. The average time interval for the ankle fusion was 140.8±25.7 days. The postoperative modified American Orthopaedic Foot and Ankle Society (AOFAS) Hindfoot score was 67.5±9.6 points.Conclusions: Ilizarov assisted ankle arthrodesis aids in early weight bearing, better alignment, and has good functional outcomes even in cases with previously failed procedures. It has the advantage of postoperative readjustment of the arthrodesis without the need of any second procedure with no major complications.
