Midterm assessment of subtalar arthroereisis for correction of flexible flatfeet in children.

Background: The role of subtalar arthroereisis (STA) for treating flexible flatfoot (FFF) in children is controversial. We hypothesized that (1) STA provided significant radiographic correction of low longitudinal arch and forefoot abduction in paediatric FFF and that (2) mid-term clinical outcomes were satisfactory and comparable to a normal population.

Methods: A retrospective comparative study was performed of paediatric patients with symptomatic FFF who underwent STA between 2012 and 2015.
