Pes Cavus Treatments


Pes Cavus, known also as a high instep, talipes cavus or supinated foot, is a foot condition classified by an arch that does not fall flat upon bearing weight. In Latin, pes cavus stands for ?hollow foot?. It is medically described as a multi-planar foot deformity most recognized by the presence of a noticeably high arch. Pes Cavus is known to occur in approximately 8-15% of the population, however, it is far less recognized than its counterpart, Pes Planus.


There are different causes of a high-arched foot. In many cases, the cause is unknown. In other cases, the cause is a nerve disease, clubfoot or injury. Treatment ranges from changes in shoewear to surgeries, depending on the amount of deformity and related problems.


How long do you grow during puberty? - may notice that your heel is curling downward at the ankle, toward the ball of your foot. Also, if you sit with your feet hanging down, the front of your foot will hang lower than the back of your foot. That is due to the muscles that pull your foot inward being stronger than the ones that pull your foot outward. Your foot may also be shortened a bit, and might be rather stiff.


Diagnosis of cavus foot includes a review of the child?s family history. A foot exam to look for a high arch, calluses, hammertoes and claw toes. A test of muscle strength in the foot, toes, ankle and leg. Observing the child?s walking pattern and coordination. X-rays. Other testing - may include electromyogram and nerve conduction velocity (EMG/NCV) studies, blood test for CMT and magnetic resonance imaging (MRI) study of the spine and brain.

Non Surgical Treatment

Cavus foot sometimes may be treated without surgery. These options include orthotic devices that fit into the shoe to provide stability and cushioning. Shoes with high tops to support the ankle and wider heels for stability. Bracing to keep the foot and ankle stable.

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.
