Background: Subtalar arthroereisis has been described as a minimally invasive,
effective, and low-risk procedure for the treatment of flatfoot in children.
Purpose: To test the effectiveness of the subtalar extra-articular screw arthroereisis
procedure as a corrective measure for flexible flatfoot (FFF) in children.
Material and methods: From 2012 till 2014, eight children with 12 feet with flexible
flatfoot were treated with Subtalar extra-articular screw arthroereisis at Banha
University and Banha Insurance Hospitals.
With a mean age of 10.5 years and ranges between 5 to 16, 5 male and 3 female
patients were selected and were required to follow-up every 18 months (range 15-27
months).
Results: This technique offered worthy results to correct idiopathic flat foot for
children, due to its less invasive and less damaging nature for the structures of sinus
tarsi. Based on clinical inspections and X-ray measurements, there was clear
improvement of foot function.
Conclusion: Subtalar arthroereisis is an effective procedure for flexible flatfoot (FFF)
correction as it is simple and can be performed rapidly. Additionally, screws
mechanical and proprioceptive effect result in notable correction of the deformity.
