No effect of preoperative ulceration on outcomes of tibiotalocalcaneal arthrodesis

Abstract

Background: Tibiotalocalcaneal (TTC) arthrodesis is a commonly performed operation for complex hindfoot pathology, but the effect of preoperative ulceration on TTC outcomes has been debated. This study aims to examine infection rates in patients undergoing TTC arthrodesis with internal fixation with and without concomitant hindfoot ulceration.Methods: We conducted a retrospective review of 31 patients who underwent a TTC arthrodesis between June 2016 and February 2021 with a fellowship-trained foot and ankle surgeon at an academic medical center. Nine (29.0%) patients had preoperative ulceration. Mean follow-up duration was 1.49 (range, 0.51-4.28) years. Other data collected included demographics, comorbidities, surgical approach, fixation method, and complication and reoperation rates. Results: There was no difference in overall complication (ulcer [U]=66.7%, no ulcer [NU]=50.0%; p = .397), infection (U=33.3%, NU=31.8%; p = .935), or reoperation (U=55.6%, NU=27.3%; p = .135) rates between groups.Conclusions: TTC arthrodesis with internal fixation appears to be a reasonable treatment method for pa-tients with a preoperative ulcer.
