Fatigue Fracture of the Tarsal Navicular

Abstract

Fatigue fracture of the tarsal navicular is an uncommon and unusual vertical type of fracture which may require special roentgenographic views and laminagraphy for detection. This type of fracture has not been previously reported in man. Two cases of fatigue fracture of the tarsal navicular in male high-school athletes have been presented. One of these fractures healed with plaster-cast immobilization and the other was treated by open reduction and internal fixation.
