Reproducibility of radiographic methods for assessing longitudinal tarsal axes part 2: Severe cavus or flatfoot study

•Calcaneal pitch and Meary’s angle are commonly used to assess foot arches.•The radiographic methods for evaluating tarsal axes differ among reports.•The most reproducible methods for assessing severe foot deformities were determined.•The results are generally consistent with those of Part 1.•The methods are optimal for radiographically evaluating foot deformity.•This study may contribute to the accurate assessment of any foot deformity.
