Relationship between stress fractures of the proximal phalanx of the great toe and hallux valgus.

Abstract

To clarify the relationship between stress fractures of the great toe and hallux valgus. Ten cases of this fracture were analyzed for their alignment of the great toe. Nine of them had hallux valgus. The continuous bowstring effect of the extensor hallux longus and shearing stress on the hallux valgus that occur during specific exercises such as sprinting, jumping, and standing on tiptoe, could cause these stress fractures. The hallux valgus could play a role in the cause of stress fractures of the proximal phalanx of the great toe.
