High Arch – Cavus Foot

This condition can be caused by a wide variety off actors. It can be present at birth, the result of an inherited structural abnormality. In many cases, however, cavus foot develops slowly – later in life -as the result of a nerve or muscular disorder. Stroke, cerebral palsy, spina bifida, Charcot-Marie-Tooth disease and other medical conditions can cause cavus foot to develop.

• Congenital abnormality
• Neurological (brain & spinal) disorders:
  • Cerebral palsy (CP)
  • Charcot-Marie-Tooth disease
  • Muscular dystrophy (MD)
  • Polio
  • Spina bifida
  • Stroke

The most obvious symptom of cavus foot is a high arch that is present even when the person is standing. Because cavus foot results in an excessive amount of pressure in the ball of the foot and heel, the person may experience foot pain, ankle instability, and calluses on the sole of the foot. The person may also develop claw toes or hammertoes.

• Calluses, especially on heel, side or ball of foot
• Drop foot
• Hammer toes or claw foot
• Heel tilted inward
• High foot arch noticeable when standing
• Instability
• Pain

Treatment depends on the underlying cause of the problem. If the condition is inherited, orthotic devices, braces or changes in footwear may be recommended to provide more support for the foot. If the cavus foot has resulted from a nerve or muscle disorder, the underlying cause will be treated. In many cases, surgery is needed to correct the deformity.

• Supportive braces can provide stability to both the foot and ankle.
• Custom orthotic shoe inserts and/or high-top or special, wide-bottom shoes may provide support, stability and cushioning.
• Surgery may be required to relieve pain and improve stability.
