Q66: Congenital deformities of feet

Q66.7: Pes cavus

The sole of the foot normally has a slight upwards arch from front to back. The sole of the foot is arched, particularly on the inside of the foot. The arch is important so that the foot can cushion the body’s weight when walking and standing. Connective tissue and muscles stabilize the arch in the foot.

With a high arch, the sole of the foot arches upwards more than usual. A high arch can accompany nervous system disorders. With disorders of this type, muscles in the foot that normally stabilize the arch may be paralyzed.
