[Options and limits of subtalar arthroereisis in childhood]

The minimally invasive subtalar screw arthroereisis procedure is becoming an increasingly more established option for treating juvenile flexible flatfoot. The procedure is indicated in children who are 9-13 years old and have idiopathic juvenile flexible flatfoot that has progressed to a symptomatic pathology. Minimally invasive subtalar screw arthroereisis functions by a combination of mechanical and proprioceptive effects that allow for growth adjustment of the subtalar joint and with a low complication rate. This surgical intervention is contraindicated for treating fixed and secondary pes plano valgus. The subtalar screw is removed once the pediatric foot has stopped growing and results in permanent correction of the flexible flatfoot.
