Children with cavus foot have arches that are much higher than usual. Often, their heels point inward, and all of their toes are flexed. Children with cavus foot have trouble finding shoes that fit. The tops and middles of their feet become sore. They may have pain, and develop thick calluses under the ball and at the outer edges of their feet. Because their high arches make their ankles roll outward slightly, children with cavus foot may feel like their ankles are about to give out. Sometimes they sprain their ankles over and over again.Causes
The most frequent cause of cavus foot in children is a nerve or muscle disease. The condition usually is not present at birth but rather develops slowly How long do you grow during puberty?
the first 10 years of life. Among cavus foot?s most common causes are Charcot-Marie-Tooth disease (CMT), Spina bifida, Polio, Muscular dystrophy, Injuries to the nerves in legs or spinal cord, Injuries to the leg muscles, Cavus foot also may be an inherited structural abnormality.Symptoms
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.Diagnosis
To diagnose cavus foot, your doctor will examine your foot and review your medical history. In most cases, your foot will undergo muscle testing and your walking pattern will be evaluated. To provide a more accurate diagnosis, x-rays may also be done in certain cases.Non Surgical Treatment
Non-surgical treatment is instituted early and is chiefly delivered by podiatrists and orthotists, preferably working alongside doctors in a foot and ankle clinic. Orthotic treatment can broadly be separated into four types, pressure relief, correction of deformity, accommodation of deformity, and splinting. Chiropodists and podiatrists can provide simple devices, but more involved orthoses are made by an orthotist. A simple cushioning orthosis alone may help symptoms from pressure overload. Pressure on the metatarsal heads is alleviated by a total contact orthosis that widens the contact area. One randomised controlled trial has compared custom-molded, semi-rigid orthoses with soft, sham inserts. The custom inserts caused a clinically and statistically significant reduction in foot pain scores and peak plantar pressure at three months, and a significant increase in quality of life measures.Surgical Treatment
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. The surgeon 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.
