Surgical correction of a simian foot.

Congenital varus deformity of the first metatarsal can be secondary to the abnormal insertion of abductor hallucis, a space-occupying lesion of the first web space, or hypoplasia of the metatarsal. We report a unique case where all three factors were present in one foot. This was combined with talipes equinovarus, which gave the appearance of a simian or hand-like foot.
