摘要

根据一些参考资料,亚洲人的一些日常活动与西方人不同,需要更大的活动范围。因此,一种适合亚洲人活动的双活动度(DM)植入体应运而生。磨损是可能缩短髋关节假体寿命的因素之一。基于计算的磨损模拟可以指导产品设计,减少粘合剂和磨料的磨损。尽管已经建立了先进的建模方法,但人们对大量的磨损仍不了解,尤其是 DM 杯上的金属-聚乙烯铰接处。至关重要的是,要检查 DM 杯头部与衬垫比的磨损情况,以确定 DM 杯适当的头部直径和衬垫厚度。在这项研究中,我们使用有限元分析方法对磨损情况进行了分析,并对 DM 杯上三种不同股骨头直径与不同厚度的聚乙烯衬垫进行了比较。在正常行走周期中,对每种股骨头与衬垫比率下的磨损情况进行了分析。这项研究的结果可用于为亚洲人开发磨损最轻微的双活动度人工髋关节。

Assessment of polyethylene wear in dual mobility implant for Asians on various head-to-liner ratios: A finite-element analysis
Based on several references, Asians carry out several daily activities that are different from Westerners, which require a greater range of motion. Because of that, a dual mobility (DM) implant was created that was adapted to the activities of Asian people. One of the factors that might shorten the life of a hip implant is wear. Simulations of wear that are based on computation can guide product design to reduce the amount of adhesive and abrasive wear. Even though advanced modeling approaches have been established, a great deal of wear is still not understood, especially regarding the metal-on-polyethylene articulations found on DM cups. It is critical to examine the wear on the DM cup's head-to-liner ratio to determine the proper head diameter and liner thickness for this DM cup. In this work, wear was analyzed using finite-element analysis and compared between three different femoral head diameters matched with different thicknesses of the polyethylene liner on DM cups. Wear was analyzed throughout the regular walking cycle at each head-to-liner ratio. The findings of this study can be used to develop a dual-mobility artificial hip joint for Asians with the slightest wear.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
