Lateral fibula insufficiency has historically been considered a contraindication for arthrodesis takedown and conversion arthroplasty. Studies have described several methods for restoring an adequate lateral buttress but reported mixed results. The authors describe a novel technique tip for a single-procedure conversion of tibiotalocalcaneal arthrodesis to total ankle arthroplasty in the setting of fibular deficiency. The described technique uses unique templating and bone cuts and can be successfully replicated in these challenging cases. Level of Evidence: Level V—expert opinion.
