Flexible flatfoot is the most prevalent condition seen in pediatric orthopedic clinics. It is characterized by an absence of the medial arch and a valgus position of the calcaneus. The purpose of the present study was to report on the results obtained in children treated using the calcaneo-stop procedure. A total of 410 flatfeet in 242 consecutive patients were treated using the calcaneo-stop procedure from January 1999 to March 2010 (10 years, 3 months) and were followed up to February 2012. The mean age at surgery was 11 (range 7 to 14) years, and the mean follow-up duration was 88 (range 14 to 157) months. A clinical evaluation, podoscopic examination, and radiologic assessment were performed in the participating patients preoperatively and at 6 months postoperatively. Of the 242 patients, 168 (69.42%) underwent bilateral foot surgery and 74 (30.58%) unilateral intervention, involving 33 right (44.6%) and 41 left (55.4%) feet. At follow-up, the outcome was satisfactory in 397 feet (96.83%); heel valgus was observed in only 12 feet (2.92%), and the footprint was normalized in 328 feet (80%). The calcaneo-stop procedure is a simple, reliable, and minimally invasive procedure for the treatment of pediatric flexible flatfoot. It allows alignment of the talus and calcaneus, restoring a proper foot arch.
