Semiautomated Weight-Bearing CT-Based 3D Analysis of Normal Foot and Ankle in a Korean Population: A Comparison With European Data

test was used to compare the parameters between male and female participants within the Korean cohort. Pearson correlation analysis was performed to assess the relationship between age and the measured foot parameters.ResultsStatistically significant differences were observed in 18 of the measured parameters between the Korean and European cohorts. The Korean cohort showed a significantly lower sagittal Meary angle, higher talonavicular angle, and lower Saltzman view angle than European data. Analysis of the Korean cohort revealed no significant sex-based differences across most 3D WBCT parameters, except for the sagittal third tarsometatarsal angle. Age was positively correlated with axial Meary angle, Saltzman view angle, and hallux valgus angle.ConclusionThis study provides preliminary 3D WBCT reference values for the adult Korean foot and ankle. The distinct morphologic variations observed between Korean and European populations underscore the need for ethnic-specific reference values. These findings provide a foundational 3D metric for clinical diagnosis and surgical planning in East Asian populations.
