| Abstract: | Structural foot deformities consequent to Charcot Marie Tooth (CMT) can be treated by functional surgery (FS). This study aims to evaluate both long‐term walking ability and patients' satisfaction in CMT subjects who underwent FS during their lifetime. We conducted a retrospective observational study. Age, sex, CMT type, comprehensive surgical history, current walking ability assessed by the Walking Handicap Scale (WHS) and patients' global impression of change (pGIC) were retrieved from a custom database managed at our institution. WHS and pGIC were assessed between mid‐2018 and mid‐2019. Data from 79 patients were screened and 63 were included, 35W‐28M, mean age 42 (15), with demyelinating (75%), axonal (20%), and other types (5%) of CMT, who underwent FS between 1967 and 2018. FS evolved significantly over the years from bone‐related procedures (e.g., arthrodesis) to both bone and soft tissues‐related procedures. The re‐intervention rate decreased from 70% before 2000 to 32% in the last decade. Complications arose in five cases. FS was mainly performed on adults (73%). WHS was ≥ 5 in three‐quarters of the sample (range 1‐6) and was significantly affected by age groups in patients with demyelinating CMT (n=47, p<0.01, non‐parametric ANOVA). Nearly 80% of patients were satisfied with FS (pGIC ≥ 4). In conclusion, CMT subjects who underwent FS surgery maintained a high gait efficiency in the long‐term period, with middle to high levels of satisfaction in the majority of the cases. This confirms the validity of FS in the management of acquired foot deformities in CMT patients. |
