A cavus foot has a high arch. The cavus can range from being slightly high to severely deformed, causing a patient to walk on the outside of the foot. Surgery sometimes is needed to realign the foot.
While the cause of a high-arched foot it often unknown, a cavus could be caused by nerve disease, clubfoot, or injury. Treatment ranges from changes in shoes to surgeries, depending on the amount of deformity and related problems.
The main goals of cavus foot surgery are to reduce pain, improve function, and prevent further damage or injuries.
