Cavus deformities (High Arch) of the foot are characterized by an elevated arch while standing. While there may be no underlying cause, it is 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 Friedeich ataxia; spine abnormalities such as tethered cord syndrome, diastematomyelia, syringomyeliaorspina 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 not already known. Nonsurgical treatment may have a role in some patients, such as a supportive orthotic device. Most cavus deformities require surgery for correction. Cavus feet in children that have an underlying progressive neurologic condition may recur after surgery, and additional surgery may be required.
