About this study

VARIABLES TO BE COLLECTED AND SOURCE The primary efficacy endpoint will be the maintenance of flatfoot correction over time, assessed both clinically (tip-toe test, Jack test, tip-toe walking test) and radiologically (evaluation of Meary's angle on the lateral foot view and the talocalcaneal angle). The secondary efficacy endpoint will be the absence of pain at follow-up, assessed using the VAS scale, and evaluation of the footprint using a podoscope. TIP-TOE TEST: The patient is observed under weight-bearing conditions and then while rising onto the toes. If the foot is flexible, the plantar arch-previously absent-reappears when standing on tip-toe. JACK TEST: This consists of passive dorsiflexion of the hallux under weight-bearing conditions. If the previously absent arch reappears, the flatfoot is considered flexible. TIP-TOE WALKING TEST: The patient walks for about ten steps on tip-toe. The examiner observes any varus alignment of the hindfoot and reconstruction of the plantar arch. MEARY'S ANGLE: Measured between the longitudinal axis of the talus and that of the first metatarsal on a weight-bearing lateral foot radiograph. TALOCALCANEAL ANGLE: Measured between the longitudinal axis of the talus and that of the calcaneus on a weight-bearing dorsoplantar foot radiograph. VAS: The Visual Analog Scale for pain is a tool used to measure the subjective characteristics of pain experienced by the patient, ranging from 0 (no pain) to 10 (worst imaginable pain). PO…
