Approximately 5 % of the adults in Germany over the age of 60 suffer from hip joint arthrosis. Today, the implantation of a hip endoprosthesis is one of the 20 most frequently performed operations in Germany, with more than 200,000 primary operations per year. The aim of the “BioniCera” research project is to develop a hip endoprosthesis with a bionic ceramic guide structure that enables high-strength bone ingrowth. To realize the innovative composite material of the implant, the conventional titanium prosthesis stem is combined with an alumina-based ceramic. The ceramic contains a bionic guide structure of branched channels that enable bone ingrowth and thus long-term anchoring of the prosthesis in the bone. In the presented study, the focus is on the selection of the fiber material to create the capillaries of the bionic guidance structure, as well as the ceramic.
