Hallux valgus and metatarsus adductus: the surgical dilemma.

Hallux varus in the presence of metatarsus adductus is a complex clinical entity that requires careful evaluation and preoperative planning. The metatarsus adductus complicates the picture by accentuating the effect of the intermetatarsal angle and also creates compensatory pronation. Transpositional osteotomies of the first metatarsal are difficult to perform in patients with an adducted forefoot and mild increase in intermetatarsal angle. Surgical therapy generally requires aggressive osteotomies of the first ray to decrease its medial prominence. Total metatarsus adductus correction should be considered in patients with severe deformity.
