What causes Cavus Foot?
It is a condition in which the foot has a very high arch. Because of this arch, an excessive amount of weight is placed on the ball and heel of the foot when walking and standing. It can develop at any stage and can occur in one or both feet.
Children are rarely born with this problem. Instead, cavus foot usually develops slowly over the first 10 years of life.
It is often caused by a neurological disorder or other medical condition such as cerebral palsy, Charcot-Marie-Tooth disease, spina bifida, polio, muscular dystrophy, or stroke. It can be inherited structural abnormality.
The arch of a cavus foot will appear high even when standing. In addition, one or more of the following symptoms may be present:
- Hammertoes (bent toes) or claw toes (toes clenched like a fist)
- Calluses on the ball, side, or heel of the foot.
- Pain when standing or walking.
- An unstable foot due to the heel tilting inward, which can lead to ankle sprains.
- People with cavus foot may also experience foot drop, a weakness of the muscles in the foot and ankle that results in dragging the foot when taking a step.
- Doctor review the patient’s family history. The foot an ankle surgeon examine the foot, looking for a high arch and possible calluses, hammertoes, and claw toes. The foot is tested for muscle strength, and patient’s walking pattern and coordination are observed. The pattern of wearing the shoes is also studied.
- X-rays are sometimes ordered to further assess the condition. In addition, the surgeon may refer the patient to a neurologist for a complete evaluation.
- Blood test for CMT disease.
- MRI of the spine and brain.
- Electromyogram and nerve conduction velocity studies.
There are non-surgical treatments for cavus foot which may include:
Orthotic devices: Custom orthotic devices that fit into the shoe can be beneficial because they provide stability and cushioning to the foot.
Shoe modifications: High-topped shoes support the ankle, and shoes with heels a little wider on the bottom add stability.
Bracing: The surgeon may recommend a brace to help keep the foot and ankle stable.
If non-surgical treatment fails to adequately relieve pain and improve stability, surgery may be needed to decrease pain, increase stability, and compensate for weakness in the foot. After surgery recovery requires at least six weeks of non-weight bearing so the bones and other structures can heal.
