Constrictive footwear is therefore thought to be a predisposing factor.Metatarsus primus varus, or medial deviation of the first metatarsal with an increased first-second metatarsal angle, is commonly associated.The combined deformities are present to some degree in most patients (14, 15).Up to now, this has not been part of a routine foot series.Hallux valgus is used to describe lateral deviation of the great toe.Recent studies have shown that a tangential view of the sesamoids (“sesamoid” view) provides a more accurate assessment of of sesamoid position and degree of subluxation (17).They are tethered to the 2nd metatarsal by the intermetatarsal ligament and by the adductor hallucis.Because of this, the sesamoids maintain a constant relationship with the 2nd metatarsal.Heredity also plays an important role in the development of Hallux Valgus (14, 15).Some believe that metatarsus primus varus is secondary to hallux valgus.The medial and lateral sesamoids are attached to the flexor hallucis brevis, which in turn is attached to the base of the first proximal phalanx.

However, many now believe that hallux valgus is a result of metatarsus primus varus, and surgical correction is often based on this theory.
