INCORRECT

The correct answer is:

FALSE:

There is no universally accepted clinical or radiographic criteria for defining relationships of forefoot and hindfoot in flatfoot, skewfoot, or metatarsus adductus. there is no agreement how much forefoot adduction is needed to reclassify flatfoot as skewfoot. In 1986 Berg first attempt to classify metatarsus adductus and skewfoot radiographically, however, this study has faults and has not become widely used.
