This study evaluated whether preexisting hypothyroidism is associated with increased complications following surgical treatment of ankle fractures.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n \n Adults undergoing operative ankle fracture fixation or related ankle fracture surgery in TriNetX were stratified by hypothyroidism diagnosed within 6\u2009months before or on surgery vs no recorded hypothyroidism history. Propensity score matching was performed 1:1 using demographic factors, diagnosis-coded obesity\/overweight, hemoglobin A\n 1c<\/jats:sub>\n , tobacco-related variables, diabetes, chronic kidney disease, cardiovascular disease, chronic obstructive pulmonary disease, peripheral vascular disease, and osteoporosis. No single primary outcome was designated; all 6 outcomes were assessed on an equal, exploratory basis at 3\u2009months, 6\u2009months, and 1\u2009year.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n After matching, 10\u2009406 patients per cohort were included in the 3- and 6-month analyses, and 10\u2009407 per cohort were included at 1\u2009year. With the numbers available, no significant difference could be detected for any 3-month outcome. At 6\u2009months, nonunion\/malunion (RR, 1.305; 95% CI, 1.065-1.600; RD\n P<\/jats:italic>\n \u2009=\u2009.010) and hardware failure (RR, 1.302; 95% CI, 1.058-1.602; RD\n P<\/jats:italic>\n \u2009=\u2009.013) were higher in hypothyroid patients. At 1\u2009year, nonunion\/malunion (RR, 1.407; 95% CI, 1.166-1.698; RD\n P<\/jats:italic>\n \u2009<\u2009.001) and hardware failure (RR, 1.264; 95% CI, 1.065-1.500; RD\n P<\/jats:italic>\n \u2009=\u2009.007) remained higher. Infection, hardware removal, wound dehiscence, and broad procedure-related complications were not significant at any time point.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n \n In this propensity-matched retrospective cohort study, preexisting hypothyroidism was associated with modest but statistically significant increases in delayed osseous and hardware-related complications after operative ankle fracture surgery (\n P<\/jats:italic>\n \u2009<\u2009.05 for both outcomes at 6\u2009months and 1\u2009year).
