Tibiotalocalcaneal arthrodesis with distal tibial allograft for massive bone deficits in the ankle.

<bold>Background: </bold>The purpose of this study was to assess the outcomes of distal tibial structural allograft to obtain a stable TTC fusion.<bold>Methods: </bold>Retrospectively, ten patients were carried out with a minimum one year follow-up. The median age was 72 (33-81). The median BMI was 28 (24-33). Indications for TTC arthrodesis included failed total ankle arthroplasty (n=7 patients), prior nonunion (n=2 patients), and a trauma injury.<bold>Results: </bold>Union rate was 80%. The median initial height of the distal tibial allograft was 19mm (14-24mm). In seven cases the allograft did not lose height. The AOFAS score median was 69 (31-84). SF-12 median physical component was 39 (30-53), and 59 (23-62) for mental component. The VAS median was 2 (0-8).<bold>Conclusions: </bold>TTC using distal tibial allograft shows a lower rate of collapse than other structural grafts and provides a fusion rate higher or in accordance with the literature.<bold>Level Of Evidence: </bold>Level IV, retrospective case series.
