Typical features of a metatarsal stress fracture of the 3^rd digit.

The diagnosis of the hallux valgus is made on a weight bearing foot radiograph, but in this case, typical changes around the 1^st MTP joint are seen:

• lateralization of the great toe sesamoids - due to a medial shift of the 1^st metatarsal head
• bursitis in the adventitial bursa adjacent to the medial metatarsal eminence - because of the pressure of the footwear and the medial eminence (due to deviation of the metatarsal head and subsequent change of medial eminence shape)
