Medial Column Fusions in Flatfoot Deformities: Naviculocuneiform and Talonavicular.

Abstract

Progressive collapsing foot deformity (PCFD; commonly referred to as flatfoot deformity) is a complex condition classically characterized by hindfoot valgus, midfoot abduction, and forefoot varus. Medial column arthrodesis can be used to reliably correct severe, arthritic, and unstable PCFD involving the medial column. Although both naviculocuneiform arthrodesis and talonavicular arthrodesis have their own indications, patient selection and careful radiographic and clinical assessment are crucial for any medial column arthrodesis. Herein, the authors discuss the indications for medial column arthrodesis procedures, outcomes as reported in the literature, and several case examples using medial column arthrodesis in deformity correction.
