Surgical Treatment Using Polymeric Implant for Flexible Flatfoot in Children Aged 8 to 14 Years

What this Trial Is About

Researchers are evaluating surgical treatment called arthrorisis of the subastragalus joint using a polymeric implant to address flexible flatfoot in children aged 8 to 14 years. This condition involves joint deformity causing flat feet, and the study aims to analyze clinical and radiographic outcomes over time during growth. The trial is a prospective observational study involving 55 patients to better understand the treatments effects. The surgical procedure uses a polymeric endorthesis designed to restore proper alignment between the astragalus and calcaneus bones and maintain this correction over time. The goal is to allow natural bone remodeling along growth lines, usually within a few years. This study tracks patients undergoing this specific surgery without comparing other treatments. Participants will be monitored regularly with measurements of Mearys angle at baseline and multiple follow-up points up to 72 months after surgery. Additionally, the American Orthopaedic Foot & Ankle Society AOFAS scores will be assessed at the same intervals. These evaluations help assess the joint alignment and foot function over time. The study will continue collecting data and monitoring outcomes until 2028.
