中文摘要
全髋关节置换术中使用的超高分子量聚乙烯(UHMWPE)内衬。近年来,内衬的厚度越来越薄,直径越来越大,活动范围越来越大。在本研究中,在标准模拟器测试条件下,使用3.5/4.0 mm厚度和44 mm直径的PE内衬进行髋关节模拟器测试,最多进行500万次循环。与未掺杂的PE内衬相比,掺杂0.1% α-生育酚(0.1%重量)的髋臼杯没有磨损优势。
英文摘要
The ultra highly molecular weight polyethylene (UHMWPE) liner used in total hip replacement. Recently, thinning of thickness and large-diameter of liner is progressing for the range of motion improved. In this study, hip simulator test had run by using 3.5/4.0mm thickness 44mm diameter PE liner under standard simulator test conditionsup to 5 million cycles. Compared to non doped PE liner, There was no wear advantage related to 0.1% alpha-tocopheral (0.1% by weight) doped cup.
