Pedobarography is a common tool for the evaluation of foot deformity. We describe our radiographic and pedobarographic outcomes of surgical treatment of cavovarus foot deformity in children with Charcot-Marie-Tooth disease. Nineteen patients for a total of 30 feet were included. Preoperative and postoperative dynamic pedobarographic measurements were made and analyzed using the five-mask technique. Pedobarographic measures showed statistical significance for increased contact area and decreased peak forces in most mask areas after surgical treatment. Peak pressure and redistribution of varus pressure patterns trended toward improvement. We found pedobarographic studies helpful; however, pedobarographic data are somewhat difficult to interpret and should be used in addition to clinical and radiographic examination.
