Cavus foot pain can be a difficult and challenging problem. It is far less common to see a high arch patient with foot pain than a low arch patient with foot pain. As a result, high arch feet are less commonly treated or may be less understood than the common flatfoot.
Furthermore, Charcot Marie Tooth muscular dystrophy has been associated with high arch feet and may lead to muscle imbalance issues that make the high arch foot more difficult to diagnose and treat. Accordingly, let us take a closer look at the workup and treatment options of the high arch foot.
Patients who present with symptomatic high arch feet often note pain on the lateral column of the foot, instability of the lateral ankle and pain under the ball of the foot, especially under the first metatarsal bone. Problems such as plantar fasciitis can also occur with high arch flexible feet as the arch stretches during the gait cycle, causing stretching of the fascia. Patients usually feel like they are falling over on the outside of the ankle and may even find swelling and pain in the lateral foot and ankle. Severe cases of cavus may even lead to lateral column stress fractures.
