Pes Cavus

Pes cavus is an abnormally high arched foot. People with this condition place too much weight and stress on the ball and heel of the foot at the time of standing or walking.

Causes of Pes Cavus

Pes cavus can be caused by an underlying disease, injury, or an inherited foot problem. Causes of pes cavus include:

  • Polio
  • Spinal cord tumor
  • Charcot-Marie-Tooth disease
  • Muscular dystrophy
  • Cerebral palsy
  • Friedreich ataxia
  • Clubfoot
  • Compartment syndrome
  • Crush injury
  • Structural abnormality
  • Inherited condition

Risk Factors related with Pes Cavus

Pes cavus has a tendency to run in families. If you are having a family member who is living with very high arches, then you may be at increased risk for developing pes cavus.

Diagnosis of Pes Cavus

The doctor will ask you about your symptoms and medical history. A physical exam will be done. You will also be asked about your family medical history. Your foot will be checked closely. Your doctor may move your foot around to assess range of motion.

You can also be referred to a specialist. An orthopedist specializes in bones. Podiatrists specialize in feet. The condition can be caused by a nervous system condition. In this case your doctor may refer you to a neurologist.

Images may need to be taken of your foot. This can be done with x-rays.


There are no known guidelines to prevent pes cavus from developing.

  • Foot pain
  • Stiff joints

  • Foot drop—the foot does not flex up
  • Instability


Treatment for Pes Cavus

Talk with your doctor about the best plan for you. Options include the following:

Supportive Devices

Changes may need to be made to provide foot support:

  • Orthotic devices are custom-made inserts which are placed into shoes that provide support, stability, and cushioning.
  • Soft-soled shoes, wider shoes, and high-topped shoes can help in managing symptoms.
  • Braces may be recommended to position the foot or to treat foot drop, which can interfere with normal walking.
  • Pads may be recommended to cushion your feet to prevent corns and calluses from developing.


In some of the instances, medical treatment is not effective, so surgery is considered. The type of surgery depends on what is causing the pes cavus. One type of surgery, called an osteotomy extracts part of the bone to correct the problem.
