When it comes to total hip replacements, choosing the suitable material combination is of clinical relevance. The present review article examines the technical differences in wear and corrosion of the relevant material combinations of ceramics, metals, ceramized metals and various types of polyethylene. The material characteristics, which were often tested under standardized conditions in the laboratory, are compared with clinical results on the basis of evidence-graded clinical studies and on the basis of register studies. This article thus represents an up-to-date snapshot of the expectations and actual clinical outcomes of the present choice of material combinations. It shows that some tendencies from the field of materials research, e.g. with regard to cross-linked polyethylene, coincide with observations from practical clinical experience, while for other materials, a proven technical superiority has not yet been confirmed as an evident advantage in clinical practice.
在全髋关节置换方面，选择合适的材料组合具有临床意义。本综述文章探讨了陶瓷、金属、陶瓷化金属和各种类型聚乙烯等相关材料组合在磨损和腐蚀方面的技术差异。这些材料特性通常在实验室标准化条件下进行测试，并根据循证分级临床研究和登记研究，与临床结果进行比较。因此，本文代表了当前材料组合选择的期望和实际临床结果的最新概况。结果表明，材料研究领域的一些趋势，例如关于交联聚乙烯的趋势，与实际临床经验的观察结果一致，而对于其他材料，已证实的技术优势尚未在临床实践中被确认为明显优势。
