N/A pediatric flexible flat foot. Intervention 1: Twenty-five children with a flexible flat foot candidate for subtalar arthroereisis surgery will be enrolled in the study and will be prospectively evaluated. These children were treated medically before surgical treatment. All patients are supine and under general anesthesia. A 2cm incision is made in the lateral malleolus at the site of the anteroinferior, and the calcaneo-stop screw is then inserted into the heel bone at the entrance of the tarsus sinus to limit the movements of the talus. It is built to maintain the physiological and anatomical structure of the talus and calcaneus. Surgery will be performed at Kashani Hospital and all by a surgeon. Intervention 2: Twenty-five children with flexible flatfoot are candidates for Lateral calcaneal lengthening surgery. These children were treated medically before surgical treatment. All patients were supine and under general anesthesia. A 3 cm incision was made at the anterior third of the heel bone, and between the anterior and middle articular surface of the calcaneal osteotomy was performed, followed by an allograft at the osteotomy site.
