Operative correction of cavovarus foot deformity in Charcot-Marie-Tooth disease (CMT) is challenging. This progressive peripheral sensory and motor neuropathy commonly involves the forefoot, midfoot, hindfoot, and toes. The authors present a new imaging technique that allows the surgeon to assess the flexibility of the hindfoot in patients with CMT to determine the best operative procedure to correct the deformity. Twenty-five patients (41 feet) with CMT and cavovarus foot deformity were evaluated and a new radiographic technique was studied in some of these patients to determine the usefulness of this imaging modality. The authors believe that this new imaging method will aid in determining the optimal operation for correcting this complex deformity.
