Prevalence of midfoot arthritis and lesser toe deformities.
Foot and Ankle Surgery : Official Journal of the European Society of Foot and Ankle Surgeons 2024 March 6
BACKGROUND: The aim of this study was to investigate the epidemiology of Midfoot Arthritis (MA) and Lesser toe deformity (LTD) using Weight-Bearing Computed Tomography (WBCT).
METHODS: 606 cases (247 male, 359 female) among 1316 consecutive cases with WBCT data from September 2014 to April 2022 were retrospectively reviewed at a single referral institution. The Cochran-Armitage test was performed to evaluate the trend of prevalence with respect to age group and obesity classification.
RESULTS: 139 male (56.3%) and 210 female cases (58.5%) showed MA. 157 male (63.6%) and 222 female cases (61.6%) showed LTD. 115 male (19.0%) and 157 female cases (25.9%) showed both MA and LTD. The prevalence of MA and LTD increased with age in both genders. The incidence of MA in males showed an increasing tendency until obesity class II and then was slightly decreased in obesity class III. This is contrary to females whose prevalence increased with increasing obesity groups. LTD had a similar pattern in both genders to obesity classification.
CONCLUSIONS: The prevalence of MA and LTD increased with age and increasing obesity groups for both genders.
LEVEL OF EVIDENCE: Level III, Retrospective Comparative Study.
