Effect of different subtalar joint arthroereisis implants on pediatric flexible flatfoot: a finite element analysis.

ABSTRACT:

Background

Flexible flat foot is a relatively common disease treated by foot and ankle surgery, and subtalar arthroereisis (STA) has gradually become favored by foot and ankle surgeons due to its advantages. However, which sinus tarsi implant is optimal remains controversial. The purpose of this study was to compare the biomechanical outcomes of two types sinus tarsi implants of different sizes via finite element analysis.

Methods

A finite element model of pediatric flexible flatfoot deformity was established in which virtual surgery of STA was simulated. Boundary and loading conditions were assumed from the data of previous finite element analysis study. The corrective ability in talar-first metatarsal angle, talonavicular coverage angle, calcaneus pitch angle, and arch hei
