Injection Molding Process and Properties

More than 80% of failures following Total Hip Arthroplasty (THR) procedures are due to implant loosening, which is strongly related with weak osseointegration. Current instrumented prostheses were designed to store only physiologic data [Damm, 2010; Heinlein, 2009]. The design of failure detection systems for hip implants is been performed [Marschner, 2009; Alpuim., 2008]. The current methodology to optimize such implants collects real-time data from the internal environment of the implant and uses the information for the research of new designs, materials and surgical techniques [Stansfield, 2003; Dayton, 2005]. However, proposals that ensure long-term implant survival have not been reported yet. This paper proposes a new methodology to avoid irreversible aseptic loosening, which may prevent to a certain extent revision surgical procedures. Through remotely controlled and monitored osteoblast mechanical micro-stimulation, real-time supervision of the osteointegration process may be ensured through tools for telemedicine.
