Foot abnormalities like pes cavus don't have to get in the way of your child's life.
A condition that causes one or both feet to have very high arches, pes cavus (high-arched foot) can make walking, running or enjoying everyday activities feel uncomfortable. With this foot condition, the high arch of the foot doesn't flatten with weight bearing.
Some children with very high arches put extra pressure on both the ball and heel of their feet – leading to pain and frequent ankle sprains. For others, pes cavus causes severe foot deformities – leading them to walk on the outside of their feet.
Pes cavus looks different for every child, but our orthopedic specialists are always ready to create a treatment plan that works best for your family. We'll start by performing a careful physical exam – and taking X-rays if needed – to determine how severe your child's condition is. Sometimes, we'll take an MRI (a non-invasive imaging test) of the spine to find out whether or not your child has an underlying condition causing their foot deformity.
Specific treatments and services may vary by location. Please contact a specific location for more information.

Causes of Pes Cavus
Many pes cavus cases are caused by an underlying neurological disorder like Charcot-Marie-Tooth disease, cerebral palsy or spina bifida – all of which Shriners Children's specialists treat. Sometimes, though, pes cavus is simply an inherited abnormality.
