What are some reasons for stress fracture in the fifth metatarsal bone?

Some reasons for stress fractures in the fifth metatarsal bone include subjecting the bone to repetitive stress, says Foot Education. They are also caused when the ankle twists over in a way that forces the foot to face inward and point downward, claims Sports Injury Clinic.

Stress fractures in the fifth metatarsal bone are more likely in people who have high arches or a leg whose shape puts more pressure on the foot, says Foot Education. Sometimes, both feet are involved, though one foot is likely to prove more painful than the other. Because of the location of the break, a stress fracture in this area of the foot might be mistaken for a sprained ankle, claims Sports Injury Clinic.
