Charcot Marie Tooth (CMT) is a progressive hereditary peripheral neuropathy. The most prevalent subtype is CMT-1A, wherein patients develop a characteristic cavovarus deformity. We have reviewed a series of standing lateral foot radiographs of patients with foot deformity due to CMT, and found that the hind foot of these patients is in dorsiflexion, not equinus, and that the apparent equinus is due to plantar flexion of the forefoot on the midfoot, and actually represents a cavus deformity.
