Short and mid-term results of arthroereisis in the management of flexible pesplanovalgus in adolescents

Introduction Flexible flatfoot is a common deformity in children and adults. Various conservative and surgical procedures have been defined in the treatment of symptomatic flexible flatfoot. Surgeons have been using subtalar joint arthroereisis implant techniques for over 35 years and have routinely reported good short-term results. However, on a midterm to long-term studies there is a variation in the results. Patients and methods This is a prospective case series study to evaluate the effectiveness and complications of arthroereisis in the management of flexible pesplanovalgus in adolescents. This study included 50 feet with symptomatic flexible flatfoot all of them had arthroereisis implant insertion with or without soft tissue procedures as indicated. Result As regard clinical evaluation there is significant correction of the heel valgus angle, AOFAS score and FAAM score. As regard radiological evaluation there is significant correction of the AP Talus 1st metatarsal angle, AP Talonavicular coverage angle, Lateral talus 1st metatarsal angle, Talocalcaneal angle and calcaneal pitch angle.
