[Calcaneus displacement osteotomy in pediatric flatfoot].

Severe unstable pes valgus that can no longer be treated conservatively can be corrected and stabilized by corrective osteotomy of the calcaneus. An important advantage of calcaneus osteotomy is the conservation of the subtalar joint. Calcaneus displacement osteotomy requires less effort from the surgeon, and the correction is more effective than wedge osteotomy of the calcaneus.
