摘　　要：关节置换植入物的应用日趋增多。本文对关节置换植入物用材料的临床应用现状及发展趋势做了综述。首先介绍了关节置换植入物材料的基本要求以及国际、国内标准的相关规定。对各种植入物材料,包括不锈钢、钴基合金、纯钛和钛合金、氧化铝陶瓷、超高分子量聚乙烯和PMMA骨水泥等高分子材料以及羟基磷灰石涂层复合材料的临床应用现状等做了阐述。简要介绍了金属材料和超高分子量聚乙烯材料的发展趋势。Joint replacement implants are applied more and more widely. In this paper, the clinical application and development of materials used for joint replacement implants are reviewed. Firstly, the essential requirements for materials used for joint implants and relevant international and national standards are presented. The clinical applications of various materials, including stainless steel, Co alloy, pure titanium and Ti alloy, alumina ceramic, ultra-high molecular weight polyethylene （UHMWPE）, PMMA bone cement, and hydroxyapatite coated material, are stated. The development trends of metal and ultra-high molecular weight polyethylene are simply introduced.
