Abstract

BACKGROUND:

Both transfibular ankle arthrodesis with fibular onlay grafting and ankle arthrodesis using the Ilizarov apparatus have resulted in acceptable fusion rates. This study analyzed outcomes in the authors' practice for all patients who underwent transfibular ankle arthrodesis with fibular onlay grafting using the Ilizarov apparatus.

MATERIALS AND METHODS:

A retrospective review was conducted of all patients who experienced severe ankle pain associated with osteoarthritis, rheumatoid arthritis, talar osteonecrosis, or septic arthritis and underwent transfibular ankle arthrodesis with an Ilizarov apparatus between 1995 and 2010. Postoperative clinical outcomes were evaluated for 42 consecutive patients (43 feet) who received primary or revision ankle arthrodesis using the Ilizarov technique at two centers. Mean duration of follow-up was 4.1 (range, 1.5 to 13) years. Outcomes were assessed using the ankle-hindfoot scale of the American Orthopaedic Foot and Ankle Society.

RESULTS:

All ankles fused successfully. Mean clinical outcome improved significantly from 36.2 (range, 8 to 64) preoperatively to 77.4 (range, 0 to 86; p < .05) postoperatively.

CONCLUSION:

Transfibular ankle arthrodesis using the Ilizarov external fixation system and fibular onlay strut grafting can achieve a very high rate of bony union and lead to general improvements in clinical outcome. Forefoot stabilization with a forefoot ring achieved rigid stabilization resulting in a shorter duration of external fixation.
