The Collapsing Foot: Challenges in Diagnosis & Treatment & The Role of the Weight-Bearing CT

In this lecture we are going to talk about the evolution in the diagnosis, radiographic assessment and treatment of the collapsing foot and why terms such as posterior tibial tendon dysfunction and adult acquired flatfoot deformity are not enough to describe this complex three-dimensional derangement of the foot and ankle.  We will discuss preoperative, intraoperative and postoperative radiographic assessment of deformity correction, and the multiple measurements reported in the literature, as well as how the advent of weightbearing CT has changed the understanding, the staging and the treatment algorithm for the collapse of this biomechanical and anatomical masterpiece that we know as foot.
