## Abstract Radiopacity in the vast majority of the commercially available acrylic bone cements that are used clinically is provided by particles of either BaSO~4~ or ZrO~2~. Literature reports have shown these agents to have a detrimental effect on some mechanical properties of the cements as well

## Abstract Vertebroplasty and balloon kyphoplasty are widely used for the augmentation of osteoporosisβinduced vertebral compression fractures. Almost invariably, an injectable poly(methyl methacrylate) (PMMA) bone cement that contains a large amount of BaSO~4~ particles is used in these procedure
In all acrylic bone cement formulations in clinical use today, radiopacity is provided by micron-sized particles (typical mean diameter of between about 1 and 2 microm) of either BaSO(4) or ZrO(2). However, a number of research reports have highlighted the fact that these particles have deleterious
The deformation and fracture behaviour of some commercial acrylic bone cements have been investigated. Cements were characterized by gel permeation chromatography, dynamic mechanical analysis and scanning electron microscopy. The inΓuence of liquid to powder ratio, curing temperature, strain rate an
