Neurologic Disorders and Cavovarus Deformity.

Abstract

A cavovarus deformity results from muscle imbalances in the foot. There are several etiologies of a cavovarus foot including congenital, neurologic, post-traumatic, and idiopathic. Charcot-Marie-Tooth disease is a common genetic cause of cavovarus foot. History, physical examination, and imaging help determine appropriate treatment. The deformity can be flexible or rigid and can present in children or adults, thus treatment should be individualized to the patient. Non-operative management includes shoe wear modification, physical therapy, and bracing. Operative management consists of soft tissue releases, tendon transfers, osteotomies, arthrodesis, and repair/reconstruction of lateral ankle ligaments and peroneal tendons.
