Synthesis and characterisation of core–shell structures for orthopaedic surgery

This paperwork deals with the obtaining and characterisation of new acrylic cements for bone surgery. The final mixture of cement contains derivatives of methacryloyloxyethyl phosphate, methacrylic acid or 2-acrylamido-2-methyl-1-propane sulphonic acid. The idea of using these monomers is sustained by their ability to form ionic bonds with barium, which is responsible for X-ray reflection and by the biocompatibility of these structures. The strategy consists in the obtaining of core–shell structures through heterogeneous polymerisation, which are used for final cementʹs manufacture. The orthopaedic cements were characterised by SEM, EDX, compression resistance and cytotoxicity assays.
