Charcot-Marie-Tooth (CMT) is a progressive genetic disorder that

produces motor and sensory neuropathy that affects the legs, feet,

and hands. A dorsally based closing wedge midfoot osteotomy at the

apex of the cavus foot deformity combined with soft tissue and other

osseous procedures are procedures performed for CMT patients at The

Western Pennsylvania Hospital.

The focus of this article is to present a prospective evaluation of 3

patients using radiographic assessment, static biomechanical and the

malleolar valgus index (MVI), dynamic alignment, and function results

using the F-scan. These results demonstrate that patients have

improved function with a plantigrade foot and decreased pain.

The Short Form McGill Pain Questionnaire (SF-MPQ) showed that there

was a decrease in pain. There was a decrease in the MVI and improved

function comparing the preoperative and postoperative F-scan in all

patients. The midfoot osteotomy addresses the apex of the progressive

cavus foot deformity and provides a plantigrade foot in 3 CMT

patients.
