What is a Cavus Foot?
Cavus foot is a condition in which the foot has a very high arch. Because of this high arch, an excessive amount of weight is placed on the ball and heel of the foot when walking or standing. Cavus foot can lead to a variety of signs and symptoms, such as pain and instability. It can develop at any age and can occur in one or both feet.
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
Some 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. Foot drop is usually a sign of an
underlying neurologic condition.
Nonsurgical treatment of cavus foot may include one or more of the following options:
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. Bracing is also useful in managing foot drop.
When Is Surgery Needed?
If nonsurgical 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. We will choose the best surgical procedure or combination of procedures based on the patient’s individual case. In some cases where an underlying neurologic problem exists, surgery may be needed again in the future due to the progression of the disorder
