Charcot-Marie-Tooth disease and the cavovarus foot

Abstract

This article focuses on the cavovarus foot shape, with particular emphasis on those patients who have Charcot-Marie-Tooth disease. Recent greater understanding of this deformity has led to a better appreciation of how the underlying condition drives deformity progression and treatment of the problems associated with it. The basic science underpinning the development of Charcot-Marie-Tooth disease is reviewed and some elements of the importance of the genetic variability are emphasized. The mechanics of the development of the cavovarus foot deformity in patients who have this neuromuscular condition are reviewed and the evaluation of such patients is described. The surgical options for treatment are reviewed and the outcomes of studies relevant to surgical planning for this patient population are summarized.
