Abstract

Poly(methyl methacrylate) (PMMA) based orthopaedic bone cements contain 1-3 micro υ size radiopacifier particles. Incomplete dispersion of these particles leads to the presence of 50-200 micro υ size agglomerates. These large defects are sites of high-stress concentration that reduce the fracture toughness of PMMA. In this study, the micrometer-sized radiopacifying particles of a commercial bone cement were replaced by nanosized fillers. Both, commercial and nanocomposite PMMA bone cements were characterized using ultra-small angle x-ray scattering and low voltage scanning electron microscopy; mechanical properties were evaluated using ASTM standard tensile testing. The results showed a substantial reduction of particle agglomerate size and a significant increase in tensile properties of the nanocomposite over that of the standard microcomposite bone cement.
