Diagnosis

You will be asked 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 examined closely. Your doctor may move it around to assess range of motion.

You may be referred to a specialist. An orthopedist specializes in bones. Podiatrists specialize in feet. The condition may 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.

Treatment

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 placed into shoes that provide support, stability, and cushioning.
  • Soft-soled shoes, wider shoes, and high-topped shoes may help manage symptoms.
  • Braces may be advised to position the foot or to treat foot drop, which can interfere with normal walking.
  • Pads may be advised to cushion your feet to prevent corns and calluses from developing.
Surgery

In some cases, 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 removes part of the bone to correct the deformity.

Prevention

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