Metatarsus adductus and selected radiographic measurements of the first ray in normal feet.
Radiographic evaluation of hallux abducto valgus frequently involves the measurement of the metatarsus adductus angle, first-second intermetatarsal angle, hallux abductus angle, and proximal articular set angle. While the concept that there is a relationship between untreated metatarsus adductus and hallux abducto valgus deformity is not new, a quantifiable relationship between the metatarsus adductus angle and intermetatarsal angle, hallux abductus angle, and the proximal articular set angle in normal feet is relatively undocumented. The purpose of this study is to document relationships between the metatarsus adductus angle and the other three measurements, and to establish normal values for the intermetatarsal angle, hallux abductus angle, and proximal articular set angle within metatarsus adductus angle subgroups.
