Rheology of Acrylic Bone Cements
Biomaterials, Medical Devices, and Artificial Organs, 1981The rheological properties of setting acrylic bone cements were examined with a rotational cone and plate viscometer. The cements were tested over two orders of magnitude of shear rate to determine the nature of any non-Newtonian flow behavior. All three cements behaved with moderate pseudoplasticity (i.e., shear thinning) during setting, suggesting ...

Principles of Bone Cement Mixing
British Journal of Perioperative Nursing (United Kingdom), 2001This is the first in a series of four consecutive articles on bone cement mixing. It aims to bring to the perioperative practitioners’ attention, all of the factors that will influence the quality and reproducibility of the bone cement they produce.

Preparation of the Bone Cement
1999Cement mixing of PMMA bone cements was carried out in the past with a bowl, a spatula, the powder, and the bottle with monomer (Fig. 76). For the validation every single step of the preparation and application of the bone cement was studied in minor and major research programs and if necessary, the preparation was modified.

Properties of novel PMMA-co-EHA bone cements filled with hydroxyapatite
, 2014To design bone cements with predictable intraoperative and postoperative behavior, researchers must understand how cement formulations affect the polymerization reaction and specially the properties of the end product.

The viscosity of acrylic bone cements
Journal of Biomedical Materials Research, 1982AbstractThe viscosity of the acrylic bone cement used in total joint arthroplasty is an important material property for determination of the proper handling characteristics and interlock with bone. In this article the rheological properties of the three leading bone cements were determined over a three‐decade range of shear rates.

Genotoxicity of Acrylic Bone Cements
Pharmacology & Toxicology, 1991Abstract: The genotoxicity of conventional polymethylmethacrylate (PMMA) and a new formulation of bone cement: methylmethacrylate/n‐decylmethacrylate/isobornylmethacrylate (MMA/DMA/IBMA) were tested by micronucleus test and reverse mutation assays of Salmonella typhimurium (Ames test).

Compact bovine bone subjected to constant torsional load for long periods of time exhibits large anelastic effects. Displacements occur at the cement lines and are responsible for part or all of the long-term deformation. The absence of an asymptotic creep strain is consistent with an interpretation of the cement line as a viscous interface.

Systemic phenomena and bone cement
Irish Journal of Medical Science, 1973Three cases of systemic reaction to bone cement are reported. Two patients had a cardiac arrest immediately after insertion of the cement during total hip replacement. The third patient had bilateral total hip replacement, the second procedure being done six weeks after the first.
