Problems of bone - orthopaedic implant interactions

The paper presents main aspects of modern orthopaedic implants design and operation. Influence of implant shape and especially stiffness characteristics and stress distribution on the surface of implant, which is in direct contact with bone, are presented. As the second factor influence of implant shape on the bone remodelling processes in the macro and micro scale was analyzed. Main distribution of general bone density as well as distribution of cancellous bone trabecules in the presence of implant is analyzed. Finally, new type of surface layer (including technology of layer manufacturing) was developed. DOI: 10.17489/biohun/2008/1/4
