Stress fractures result from repeated low-intensity trauma leading to resorption of normal bone.  In these overuse injuries, damage to bone exceeds the rate of repair. Also known as fatigue fractures, stress fractures are generally seen in young, otherwise healthy individuals. These also occur in other locations, such as the tibia and femur.  Metatarsal stress fractures have been referred to as march fractures, named after similar injuries in soldiers.  

      Stress fractures of the foot most commonly affect the 2^nd and 3^rd metatarsals, classically in runners. Other foot stress fractures include the navicular, frequently in basketball players, and the 5^th metatarsal in football players.
