Children are rarely born with this problem. Instead, cavus foot usually develops slowly over the first 10 years of life. In almost all cases, children develop cavus foot because they have a nerve or muscle disease. The disease makes some of the muscles weaker than others. These unbalanced muscles work unevenly, which causes the high arch and other signs of cavus foot.Causes
Cavus foot is often caused by a neurologic disorder or other medical condition such as cerebral palsy, Charcot-Marie-Tooth disease, spina bifida, polio, muscular dystrophy, or stroke. In other cases of cavus foot, the high arch may represent an inherited structural abnormality. An accurate diagnosis is important because the underlying cause of cavus foot largely determines its future course. If the high arch is due to a neurologic disorder or other medical condition, it is likely to progressively worsen. On the other hand, cases of cavus foot that do not result from neurologic disorders usually How do you get Achilles tendonitis?
not change in appearance.Symptoms
Many people with pes cavus have no problem at all. Sometimes it can be difficult to find shoes to fit, or the feet may ache, especially around the ankle, the outer edge
of the foot or in the ball of the foot. Curled-up toes may rub on shoes.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
When there is limited deformity and rigidity, osteotomies are preferred to arthrodesis if possible, as they preserve motion. The first metatarsal is often treated with a dorsal closing wedge osteotomy, and the heel is lateralised with a sliding osteotomy. Even after a good correction with well-healed osteotomies, neurological progression may cause recurrent deformity, typically five to ten years later, necessitating arthrodesis.
