EFFECT OF HIGH TEMPERATURE MELTING ON THE MECHANICAL PROPERTIES OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE

摘要：

Ultra high molecular weight polyethylene (UHMWPE) has been the polymer of choice for total joint replacement for over forty years. Wear debris-induced osteolysis is a major cause of implant failure and revisions.1 Radiation cross-linking and subsequent melting is successfully used to improve the wear and oxidation resistance of implants but also sacrifices the strength and toughness,2 which renders early failure of the implants. It is desirable to improve both the wear resistance and mechanical properties of UHMWPE. We hypothesized that high temperature melting could improve the strength and toughness of UHMWPE, which could in turn compensate for the loss in mechanical properties induced by subsequent radiation cross-linking.
