SPECIAL SESSION 2 - Weight-Bearing CT

The foot and ankle are subject to a highly complex mechanical demand during daily living and sports activities: any biomechanical analysis shall therefore imply weight-bearing anatomical data. Recently, Weight-Bearing low dose Cone Beam Computed Tomography has enabled to obtain 3D representations and models of the foot and ankle under physiological load in daily clinical use as well as in the lab. This is a fundamental innovation which will strengthen clinical and biomechanical analyses. This special session will discuss techniques and applications of this new technology, both in research fields and clinical settings, for diagnosis, and for planning and assessment of treatments of foot and ankle disorders.
