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.
