Relationship between Stress Fractures of the Proximal Phalanx of the Great Toe and Hallux Valgus

Abstract

Purpose To clarify the relationship between stress fractures of the great toe and hallux valgus. Methods Ten cases of this fracture were analyzed for their alignment of the great toe. Results Nine of them had hallux valgus. Discussion 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. Conclusion The hallux valgus could play a role in the cause of stress fractures of the proximal phalanx of the great toe.
