There are no standardised methods for assessing the cement flow behaviour in vertebroplasty. We propose a novel methodology to help understand the interaction of cement properties on the underlying displacement of bone marrow by bone cement in porous media. Concerns related to cement extravasation in vertebroplasty provide the motivation for the development of methodologies for assessing cements (novel and commercially available) and delivery systems. Reproducible and pathologically representative three-dimensional bone surrogates are used to understand the complex rheology underlying the two-phase flow in porous media.Summary Statement
