Pes planovalgus; Flat feet; Fallen arches; Pronation of feet

• Absence of foot arch when standing
• Foot pain
• Heel tilts away from the midline of the body more than usual

An examination of the foot is enough for the health care provider to diagnose flat foot. However, the cause must be determined. If an arch develops when the patient stands on his or her toes, the flat foot is called flexible and no treatment or further work-up is necessary.

If there is pain associated with the foot or if the arch does not develop with toe-standing, x-rays are necessary. If a tarsal coalition is suspected, a CT scan is often ordered. If a posterior tibial tendon injury is suspected, your health care provider may recommend an MRI.
