Tibiotalocalcaneal arthrodesis (TTCA) is a well-established operative procedure for different severe pathologic conditions of the ankle and hindfoot joints. We present our results with a modified technique of TTCA using an intramedullary fibular strut graft in a series of complex cases of patients treated for multiple etiologies shown to have improved union rates. The technique involves inserting the fibular strut graft intramedullary after joint preparation and the use of either a Taylor spatial frame or plate and screws for definitive fixation. We reviewed the records of 16 patients who had undergone TTCA with this technique at our hospital from September 2013 to April 2015. Sixteen patients (10 males [62.5%] and 6 females [37.5%]) were included in the present study. These patients had complex cases and multiple risk factors, including diabetes, smoking, poor bone stock, and a history of previous surgeries. The mean follow-up time was 9.1 (range 9 to 18) months. Thirteen patients (81.2%) subsequently achieved union. The mean visual analog scale scores at the final follow-up examination had improved from 6.9 to 1.2. We suggest that our technique of TTCA with intramedullary fibular strut graft with fixation is a reasonable option to salvage complex cases with risk factors for operative complications.
