Progressive collapsing foot deformity: how to use new knowledge in developing countries

Abstract

The 2019 progressive collapsing foot deformity (PCFD) consensus did not only change the disease nomenclature and provided a new classification for the condition formerly known as flatfoot deformity. It was also the pinnacle of a revolution in the field in terms of knowledge and clinical perspectives. The use of advanced imaging, such as weight-bearing computed tomography, three-dimensional algorithms, and magnetic resonance, expanded the way we understand peritalar subluxation and how we can address it. However, much of these improvements felt short in terms of global reproducibility due to economic restraints. The objective of this review study is to present PCFD new concepts through the lens and realities of developing countries, considering their potentially limited access to novel technologies.
