An observational study in Subtalar Arthrorisis, Flat Feet and Growth Age, sponsored by Istituto Ortopedico Rizzoli. Recruiting at 1 site in Italy. Open to participants aged 8 Years to 14 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-08-02.
Sponsored by Istituto Ortopedico Rizzoli · Observational
Arthrorisis of the subastragalus joint represents one of the surgical treatments for addressing flexible flatfoot, a condition caused by joint deformity. The device is designed to restore the correct joint relationships between the astragalus and calcaneus, with the goal of maintaining the new and proper joint alignment over time, typically allowing for bone remodeling along natural growth lines, usually within a few years.
Several implants and various variations of the procedure have been developed.There are currently no prospective studies that assess radiographic and clinical data over time. Therefore, the purpose of this study is to prospectively analyze the outcomes of surgical intervention using subastragalus arthrorisis with a polymeric endorthesis for the treatment of flexible flatfoot during the growth period in a consecutive series of 55 patients.
173 studies on the registry are indexed under Flatfoot; 44 are open to participants now.
This study's planned enrollment of 55 is above the median of 47 across 48 observational studies indexed under Flatfoot.
