Abstract Some well-known characteristics of the commercial acrylic bone cements are not satisfactory enough, mainly, because of poor compatibility with bone tissue, high polymerization peak temperature and the cement shrinkage. Classical cement acts like a grout and not so much like glue: it fills the gap between the implant and the bone tissue, but it does not bond to nether the bone or the implant. Therefore, in Riga Technical University the cross-linked 3-D polymer structure acrylic bone cements modified with the biodegradable natural polysaccharide additives (starch, dietary fibber from pea beans or wheat bran) were elaborated. Push-out tests for bone – cement – implant models were performed to investigate the adhesive properties of new cement. FEM was applied to evaluate the biomechanical behaviour of system bone – cement – stem and to compare with experimental test data.
