Any health problems causing pes cavus will need to be treated. Increasing the height of the longitudinal support to fill in the space between the shank of the shoe and arch of the foot, as well as extending the lift to the metatarsal heads, will evenly redistribute the weight.

Pes cavus is a fixed foot deformity causing high arches, which is frequently found in association with long-standing neuropathy (either inherited or acquired). While the cause of a high-arched foot it often unknown, a cavus could be caused by nerve disease, clubfoot, or injury. Cavus foot usually affects both feet. 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. Pes cavus is a deformity of the foot which has a very high arch and is relatively stiff. Cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural hearing loss (CAPOS) syndrome is a neurological disorder. Pes cavus may be caused by another health problem, such as: Charcot-Marie-Tooth disease; Cerebral palsy; Friedreich ataxia; Spinal cord tumor; Clubfoot; Compartment syndrome; Crush injury; Risk Factors. When this is complicated by foot drop and equinus of the ankle, this is called pes equinocavovarus. Like flat-foot, its development is usually insidious and may be due to several different causes. For more information, please visit www.BestFootDoc.com Dorsal retraction of the toes is usually present and bears an important relation to its development, but is not a part of the cavus itself. A high arch with a medially angulated heel is called pes cavovarus. Pes Cavus is usually the result of an abnormal orthopedic or neurological condition. Cause. Pes Cavus is another name for a high-arched foot. Brewerton et al 5 specifically looked at the cause of pes cavus in a series of 77 patients and found subtle neurologic defects in 66% of them, leaving a large group of “idiopathic” cases. The main goals of cavus foot surgery are to reduce pain, improve function, and prevent further damage or injuries. Affected individuals may have foot abnormalities such as high arches (pes cavus), flat feet (pes planus), or curled toes (hammer toes). Alternative names for pes cavus include, high arch, high foot arch, excessively supinated foot, calcaneocavus, hump foot and Schaeffer’s Foot.

The essential feature is the increased concavity of the arch with a shortening of the structures of the sole. Pes Planus. Bilateral cases are often due hereditary or congenital causes. Causes of Pes Cavus Pes cavus can be caused by an underlying disease, injury, or an inherited foot problem. This deformity is caused by palsy of the intrinsic foot muscles, usually related to Charcot-Marie-Tooth disease. There are two general types of flatfoot: flexible flatfoot and rigid flatfoot. In other cases of cavus foot, the high arch may represent an inherited structural abnormality. This deformity does not flatten on weight bearing. Etiology Overview: The exact etiology is unknown. 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. These methods may also be used: Physical therapy ; A change in shoes, shoe inserts, or a brace to manage symptoms ; People who are not helped by these methods may need surgery. A high arch is the opposite of a flat foot, and somewhat less common. Two-thirds of the patients with pes cavus have an underlying neurologic disorder, most commonly Charcot-Marie-Tooth disease (CMT). They often have difficulty flexing the foot or walking on the heel of the foot. Common causes of pes cavus [1,3,6]: Pes cavovarus is a three-dimensional deformity characterized by rotation of the calcaneopedal unit (the foot minus the talus). Individuals with pes planus tend to have, or eventually develop, shortening of the gastrocnemius muscle and Achilles tendon due to a pronated calcaneus relative to the tibia. What problems does pes cavus cause? Direct pes cavus may be related to a variety of causes, although neurological diseases predominate in posterior pes cavus. Regardless of the etiology of the neuropathy, intrinsic muscle atrophy and imbalance among different muscles group of the leg leads to features of pes cavus including high arch, clawing of the toes, and equinus deformity. Pes cavovarus is a three-dimensional deformity characterized by rotation of the calcaneopedal unit (the foot minus the talus). Curled-up toes may rub on shoes. Of these, 11 of the 26 patients had a family history of pes cavus, and 7 of the 26 had nonspecific abnormalities upon electromyographic and nerve conduction velocity examination. Some people may not have symptoms. Causes List: Pes cavus. Pure form Pes Cavus: In this type, the front part of foot is plantarflexed on the rear part of the foot causing high arch and the position of calcaneus is not in dorsiflexion or varus. Pes cavus leads to excess pressure along the heel and metatarsal head areas, causing pain. Myopathy, and Pes cavus Diseases related with Myopathy and Pes cavus. Many people with pes cavus have no problem at all. Neurologic conditions: Up to 67% of cases due to neurologic disorder. It is also more common in women. Pes cavus cases can resultfrom hereditary or acquired peripheral neuropathies. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Vasyli ThinkTank® member Brian Hoke discusses the methodology used to evaluate the PVC Cavus Foot Type. Sometimes, the toes might be curled up and the heel drawn in. People with pes cavus may also be more prone to broken bones in the lower legs. CMT is believed to account for 50% of neurologically induced pes cavus. The high point of the arch should be located at the talonavicular joint. Neuromuscular diseases can cause changes in muscle tone associated with pes cavus. RESOURCES. Some of the causes of the condition may include: 3 Causes of Pes Cavus: 15q24 Microdeletion Syndrome; 46,XY Gonadal Dysgenesis-Motor And Sensory Neuropathy Syndrome; Amyotrophic Lateral Sclerosis 4, Juvenile Ataxia, Early-Onset, With Oculomotor Apraxia And Hypoalbuminemia; Ataxia-Telangiectasia-Like Disorder 2 ; Ataxia With Vitamin E Deficiency; Atypical … Cavus foot (sometimes known as Pes cavus) is a type of foot deformity. Treatment ranges from changes in shoes to surgeries, depending on the amount of deformity and related problems. What causes Pes Cavus deformity? Flatfeet are also referred to as pes planus, posterior tibial tendon dysfunction, and fallen arches. While all of these cases can result in significant pain and impairment, those with a neurologic cause tend to progress faster and require more in the way of medical attention.
