The Influence of Endplate-to-Endplate Cement Augmentation on Vertebral Strength and Stiffness in Vertebroplasty

Abstract

Endplate-to-endplate PMMA augmentation restores the biomechanical properties of vertebrae in clinically relevant anterior wedge fractures. Our preliminary data suggest that biomechanical models with only 25% compressive deformation unlikely form a good model to assess the mechanical effects of cement augmentation in osteoporotic fractures.
