Anteroposterior radiograph of the feet at 6 months of age showed hallux valgus with overlap of the first and second digits. Image A demonstrates the left foot with an intermetatarsal angle(IMA) of 13  and the hallux valgus angle(HVA) of 50 . Image B demonstrates an IMA of 18  and HVA of 62  on the right foot.

The left foot had an IMA of 13 and an HVA of 50  (Fig. 1).
Coronal magnetic resonance imaging of the feet at 6 months of age revealed a broad, cartilaginous component of the distal first metatarsal, suggestive of incomplete preaxial polydactyly without a supernumerary digit.

A bicondylar metatarsal head reminiscent of a forme fruste of preaxial polydactyly without supernumerary digit was evident on MRI (Fig. 2).
Anteroposterior radiograph of the feet at 14 months of age shows markedly improved hallux valgus deformities. Image A of the left foot demonstrated an intermetatarsal angle (IMA) of 17  and hallux valgus angle (HVA) of 38 . Image B of the right foot demonstrates that the new IMA and HVA were 16  and 40 , respectively.

The left IMA hadactually worsened radiographically to 17 , but the HVA had improved to 38 (Fig. 3).
Anteroposterior radiograph of the feet at24 months of age demonstrating continued improvement of hallux valgus deformities. Image A of the left foot demonstrates an intermetatarsal angle (IMA) of 8  and hallux valgus angle (HVA) of 41 . Image B of the right foot demonstrates an IMA of 8  and HVA of 32 .

HVA on the right was 32 and 41  on the left, which was consistent with prior measurements (Fig. 4).

He was able to keep up with other children without difficulty and had no problems with shoe wear. He continued to have overlap of the first and second toe (Fig. 5), but he had full, painless range of motion.
