Background: Hallux rigidus (HR) is a common degenerative arthritis of the first metatarsophalangeal joint. However, the epidemiology and risk factors of this pathology have yet to be clarified.Methods: This cohort study estimated the prevalence of and clarified risk factors for radiographic HR in individuals over 50 years old.Results: The prevalence of HR was 26.7% (161/604). Rates of grade 0, 1, 2, and 3 HR according to the Hattrup and Johnson classification were 73.3% (443/604), 16.4% (99/604), 8.0% (48/604), and 2.3% (14/604), respectively. Overall ratio of symptomatic HR was 8.1%. Univariate analysis revealed knee osteoarthritis (KOA), gout attack (GA), and hallux valgus (HV) as significantly associated with HR. The same factors were confirmed as independent risk factors for HR in multivariate analysis. All parameters were significantly associated with HR. Odds ratios of KOA, HV, and GA for HR were 1.73, 3.98, and 3.86, respectively. The presence or absence of KOA was significantly associated with severity of HR.Conclusion: Our study revealed the prevalence of HR in the elderly (≥50 years) was 26.7%, and KOA, HV, and GA were independent risk factors for HR. KOA was associated with severity of HR. |
