High-Arched Foot (Cavus Foot)
Described as a condition wherein the foot has a very high arch, cavus foot results in an excessive amount of weight being placed on the ball and heel of the foot when walking or standing. Cavus foot is often caused by a neurological disorder or other medical condition, such as Charcot-Marie-Tooth disease, cerebral palsy, polio, muscular dystrophy, spina bifida, or stroke. It can also result as an inherited structural abnormality. Symptoms can include hammertoes; calluses on the ball, side, or heel of the foot; pain when standing or walking; and an unstable foot due to the heel tilting inward. Some people with cavus foot may also experience foot drop. Nonsurgical treatment options include custom foot orthotics, EPAT, laser therapy, shoe modifications, and bracing. In some cases, surgery is necessary to decrease pain, increase stability, and compensate for weakness in the foot.
“Once we know that a patient has cavus foot, then we must investigate the cause of the problem.”
