Abstract:
BACKGROUND:As the latest generation of ultrahigh molecular weight polyethylene, vitamin E-stabilized ultrahigh molecular weight polyethylene has been widely put into use of various kinds of joint replacement. However, wear debris and osteolysis caused by that are stil the vital factor influencing the clinical curative effect. OBJECTIVE:To discuss and summarize the material characteristics and application progress of vitamin E-stabilized ultrahigh molecular weight polyethylene, and to seek the theoretical basis which can guide us to launch vitamin E-stabilized ultrahigh molecular weight polyethylene clinical y. METHODS:The first author retrieved the CNKI and Medline databases by computer. The keywords were“ultra-high molecular weight polyethylene, vitamin E-stabilized, joint replacement, application”in English. RESULTS AND CONCLUSION:Total y 92 articles were retrieved. According to the inclusion and exclusion criteria, 46 articles were included in result analysis. The results show that vitamin E-stabilized ultrahigh molecular weight polyethylene can not only enhance the physicochemical property of prosthesis, but also can integrate with free radicals to increase antioxidant rate of prothesis in order to prolong the long-term curative effect of prosthesis. However, it is stil lack of vast of clinical cases and fol ow-up as evidence. In case of that, long-term clinical efficacy remains to be assessed.
