The clinical features of 18 patients diagnosed as having preaxial Polydactyly and hallux varus were studied. There are three types of hallux varus: 1) the medial great toe is pushed out by the lateral overlapping great toe, 2) the great toe is inverted by the deformed first metatarsus, and 3) the great toe is inverted by anchoring substance of the hypoplastic or degenerative medial great toe. The general diagnosis of “hallux varus” may be reasonable based on the common appearance, but the clinical features of these three types differ from each other. The patients with hallux varus caused by anchoring of the hypoplastic or degenerative medial great toe should be strictly differentiated from the patients with hallux varus due to deformity of the metatarsus. Special consideration for treatment is needed for each type.
