Metatarsus primus varus occurs in feet which have a normal 1--2 intermetatarsal angle. Fifty-two Caucasian females, average age 18 years, were analyzed radiologically for 1--2 and 1--5 intermetatarsal angles and for metatarsophalangeal and first interphalangeal joint angles. Measurement of the 1--5 rather than the 1--2 intermetatarsal angel is a more reliable indicator of first metatarsal varus. Valgus at the first interphalangeal joint is normally greater than that at the first metatarsophalangeal joint and excessive first interphalangeal valgus (valgus interphalangeus) is significantly linked with the presence of ossia tibiale externa. The high arch foot tends either to feature valgus interphalangeus or become excessively broad. The anatomy of the ungual tuberosity is highly variable.
第一跖骨内翻发生于第一、二跖骨间角正常的足部。对52名平均年龄18岁的白种女性进行了影像学分析，测量其第一、二跖骨间角以及第一、五跖骨间角，还有跖趾关节和第一趾间关节的角度。测量第一、五跖骨间角而非第一、二跖骨间角，是第一跖骨内翻更可靠的指标。第一趾间关节的外翻通常大于第一跖趾关节的外翻，第一趾间关节过度外翻（趾间外翻）与胫外小骨的存在显著相关。高弓足往往表现为趾间外翻或变得过于宽阔。趾结节的解剖结构差异很大。
