Subtalar Arthroereisis for Surgical Treatment of Flexible Flatfoot

center dot The persistent forefoot abduction might lead to poor quality of propulsion, instability and necessitate kinematic adaptations at the foot; individuals with pronated feet may have im-plications on the underlying mechanisms of overuse injuries. center dot Publications about flatfoot treatment with subtalar arthroereisis procedures in children and the number of surgical treatments have been increased in the last 10 years. center dot According to the different biomechanical effect, the subtalar arthroereisis with endorthesis into tarsal canal (SAE) must be distinguished from the subtalar arthroereisis with calcaneo-stop procedures (SAC-stop). center dot Data collected in a review of the last 10-year period (2010-2020) show that among the 691 feet undergoing SAE, average age at surgery was 11.40 years and in the 1856 feet that underwent SAC-stop 11.69 years, while the complications rate was 9.00% and 6.38%, respectively. These data confirm that SAC-stop may have an advantage over SAE as the screw is not placed across the subtalar joint but instead into the calcaneus.
