High Arch

A cavus deformity of the foot is an elevated or high arch in the foot. While there may be no underlying cause, high arches are often the result of an underlying neurologic condition including:

  • Peripheral neuropathies such as Charcot-Marie-Tooth disease
  • Central neurologic conditions such as cerebral palsy or Friedreich ataxia
  • Spine abnormalities such as tethered cord syndrome
  • Diastematomyelia
  • Syringomyelia
  • Spina bifida

Children who develop a cavus deformity should be evaluated by a pediatric orthopaedic specialist. A referral to a pediatric neurologist may also be made to look for an underlying neurologic cause, if one is not already known. While most cavus deformities require surgery for correction, nonsurgical treatments such as supportive orthotic devices may help some patients. High arches in children that have an underlying progressive neurologic condition may recur after surgery, and additional surgery may be required.
