Stress fractures are thought to account for 16% of injuries related to sports preparation, and the metatarsals are most often involved. These fractures are commonly called march fractures, as they are commonly diagnosed among military recruits after long marches. They are also common among road runners. The second and third metatarsals are fixed while walking, thus these metatarsals are common sites of injury. The fifth metatarsal may be fractured if the foot is oversupinated during locomotion.
