Structural differences in the hindfoot, midfoot, and forefoot that contribute to this cavovarus deformity have not been fully characterized or described between disease subtypes. This study aimed to identify structural differences in the foot associated with CMT and between demyelinating and axonal subtypes in a retrospective cross-sectional study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      In this study, we use statistical shape modeling, a mathematical tool to describe morphologic averages and variation to create a 14-bone model of the tibia through metatarsals from retrospectively identified weightbearing computed tomography (WBCT) images from individuals with CMT and controls, classified as having either demyelinating or axonal disease.
