Progressive Collapsing Foot Deformity (PCFD), previously referred to as adult-acquired flatfoot deformity, is a complex 3D pathology characterized by peritalar subluxation (PTS) of the hindfoot through the triple joint complex. While historically conventional 2D radiography has been used to assess alignment and impact of this deformity, recent research by lab director Dr. Cesar de Cesar Netto has established the superiority of weightbearing CT (WBCT) imaging in diagnosis and staging of PCFD. 

The OFIRL has several lines of research dedicated to elucidating the true 3D nature and progression of this challenging clinical problem. This has started with identifying and developing several novel markers of subluxation in WBCT imaging and is working toward automated analysis of the full 3D nature of joint subluxation in the hindfoot, ankle, and forefoot. A portion of this work can be seen below.
