Cavus Foot Reconstruction in 3 Patients with Charcot-Marie-Tooth Disease

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.
