OsteoInk: Bioactive Bone Cements

Synthesis and Characterization of Poly (methyl Methacrylate-styrene) Copolymeric Beads for Bone Cements

Acrylic bone cements have been used for about 40 years to fix artificial prosthesis to bone structure. The properties of the acrylic bone cement mostly depend on the characteristics of the beads, which are the main component of the solid part of the cement. In this work beads of poly(methyl methacrylate-co-styrene) were synthesized by suspension polymerization. The objective of this study was t...

Antimicrobial activity of bone cements embedded with organic nanoparticles

Infections after orthopedic surgery are a very unwelcome outcome; despite the widespread use of antibiotics, their incidence can be as high as 10%. This risk is likely to increase as antibiotics are gradually losing efficacy as a result of bacterial resistance; therefore, novel antimicrobial approaches are required. Parabens are a class of compounds whose antimicrobial activity is employed in m...

The Biocompatibility of Bone Cements: Progress in Methodological Approach

The ideal bone graft substitute should have certain properties and there are many studies dealing with mixture of polymethylmetacrilate (PMMA) and β-tricalciumphospate (β-TCP) presenting the best characteristics of both. Scanning Electron Microscopy (SEM), for ultra-structural data, resulted a very reliable in vivo model to better understand the bioactivity of a cement and to properly evaluate ...
