Etiological factors in hallux valgus, a three-dimensional analysis of the first metatarsal

Journal of Foot and Ankle Research, 2017
Background It has been reported that hallux valgus (HV) is associated with axial rotation of the first metatarsal (1MT). However, the association between HV and torsion of the 1MT head with respect to the base has not been previously investigated.

The interobserver reliability of first metatarsal rotational component of axial sesamoid radiographs in hallux valgus

Journal of the Foot & Ankle, 2020
Objective: Hallux valgus is a progressive triplanar deformity of the forefoot with an important rotational component (RC) in the first metatarsal, which has been associated with recurrence. There is controversy about using weight-bearing vs.

Alignment of the metatarsal heads affects foot inversion/eversion during tiptoe standing on one leg in demi–pointe position: A cross–sectional study on recreational dancers

PLoS ONE, 2022
Classical ballet dancers stand on tiptoe in the demi–pointe position where the ankle is plantarflexed, and the toes extend around a mediolateral axis passing through the second metatarsal head. Foot sickling, the foot inversion/eversion when the forefoot
