1. The anatomy of the second and third metatarsals should be considered when the etiological factors of march fractures are discussed.
2. Repeated roentgenographic studies are necessary before a true diagnosis is established.
3. The majority of march fractures occur in the second and third metatarsals.
4. Long hikes and stiff army shoes predispose to this particular type of fracture. The long hikes probably cause a severe foot fatigue in new recruits, while the resistant army shoes prevent a proper take-off, and produce excessive stress and strain over the metatarsal heads.
5. Loss of the normal range of motion at the metatarsophalangeal joint, probably due to a tight capsule, predisposes to further loss of proper take-off and a resultant extra load on the metatarsal shafts.
6. The majority of these fractures are easily treated, hospitalization is not long, and the army shoe acts as an ideal splint.
