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).

PEG/SBA-15-containing acrylic bone cement with enhanced drug release
, 2020PMMA-based bone cements Formulated with PEG/SBA-15 were synthesized to achieve efficient and sustainable release of drugs. The presence of PEG/SBA-15 has a beneficial effect on the release of gentamicin (GTMC) in 70 days. The release of GTMC was improved

Absorptive and expansive behaviors of poly(methyl methacrylate-co-acrylic acid) bone cement.
Colloids and Surfaces B: Biointerfaces, 2020Some additives had provided the expansion capacity to the polymethylmethacrylate (PMMA) bone cement and also reduced its maximum reaction temperature.

Carbon allotrope materials (i.e. carbon nanotubes (CNTs), graphene, graphene oxide (GO)), have been used to reinforce acrylic bone cement. Nevertheless, the intrinsic incompatibility among the above materials produces a deficient interphase.

Penetration of Acrylic Bone Cements into Cancellous Bone
Acta Orthopaedica Scandinavica, 1983The depth of penetration of five commercial acrylic bone cements into cancellous bone was measured in vitro. Under standard, idealized conditions, cement penetration was found to vary significantly with different cements. Penetration was critically influenced by the coarseness of the cancellous bone and increased directly with the effective volume of ...

Antibiotic-impregnated acrylic bone cement
The Journal of Bone & Joint Surgery, 1976In vitro and in vivo experiments were performed to study the antibacterial and mechanical properties of Simplex and Palacos acrylic bone cements utilized for the production of acrylic cement-antibiotic composites. Acrylic cement without antibiotic had no bacteriostatic effect on Staphylococcus aureus, Escherichia coli, and Pseudomonas.

Degree of polymerization of acrylic bone cement
Journal of Biomedical Materials Research, 1975AbstractSelf‐curing poweder‐liquid admixed acrylic systems are used for internal fixation of total hip and total knee prostheses. Gel permeation chromatography revealed that the polymer chain length distributions of set cements were basically unaffected by their curing pressures.

Acrylic bone cements: composition and properties
Orthopedic Clinics of North America, 2005Cementing endoprostheses is one of the most frequently performed orthopedic procedures in the world today. The bone cements that are currently available commercially are all based on the chemical substance methylmethacrylate. Although all of them have the same chemical basis, acrylic bone cements are not all alike.
