Abstract

Category: Hindfoot; Other Introduction/Purpose: The hindfoot deformity seen in Charcot-Marie-Tooth disease (CMT) is poorly understood, and the contribution of abnormal bone morphology has never been conclusively demonstrated. The purpose of this study was to compare the three-dimensional (3D) bone morphology of the talus, calcaneus and navicular in a cohort of CMT patients versus a control population. We used the data obtained from weight-bearing computed tomography (WBCT) to reconstruct the geometric shape of each bone using 3D surface meshing techniques. Surface mesh analysis of this type is commonly used in engineering to evaluate and optimize 3D geometries and structures. Methods: A total of 17 WBCTs from 15 patients (average age 24) with CMT who underwent WBCT without previous surgeries, degenerative changes or open physes were included. These were compared to 20 healthy control WBCTs. Calcaneal measurements included the radius of curvature and the angle between the posterior tuberosity and posterior facet in the sagittal plane. Talar measurements include axial and sagittal declination between the body and neck as well as coronal rotation of the talar head relative to the body. Surface-mesh model analysis was performed comparing the average of the CMT cohort to the controls using CT analysis software (Disior Bonelogic). Means were compared with a t test (p
