Cavovarus deformity is a foot and ankle deformity which leads to significant difficulty walking.  Patients walk on the outer edge of their foot.  In some cases the foot points down into an equinus position which causes patients to walk on their toes.  The deformity usually occurs in patients with neurologic disorders.  Patients who have had a stroke frequently devolop a cavovarus foot deformity.   Other causes include severe foot and ankle trauma.  Rather than using braces, walkers, and wheel chairs patients can undergo corrective surgery to realign the foot.
