UNLABELLED
Total hip arthroplasty (THA) is one of the most common and successful surgical procedures worldwide. At the same time, it is constantly evolving, and as a consequence, advances in implant technology have led to significant improvements in the different materials of the acetabular and femoral components. The selection of bearing surfaces and their tribology are critical to achieving a successful outcome. Pseudotumors are important, and usually misdiagnosed, complications associated with hard bearing surfaces such as metal-on-metal couples. They belong to a group of reactions called adverse local tissue reaction, which can occur in the vicinity of any THA. We present 2 cases of adverse local tissue reaction associated with the use of ceramic-on-metal bearings surfaces in 2 primary THAs that were treated with modular component exchange during single-stage revision surgery.

全髋关节置换术（THA）是全球最常见且最成功的外科手术之一。与此同时，它也在不断发展，因此，植入技术的进步使得髋臼和股骨部件的不同材料有了显著改进。承重面的选择及其摩擦学对于取得成功的手术效果至关重要。假肿瘤很重要，且通常会被误诊，它是与硬承重面（如金属对金属组合）相关的并发症。它们属于一类称为局部不良组织反应的反应，可发生在任何全髋关节置换术附近。我们报告2例在初次全髋关节置换术中使用陶瓷对金属承重面后出现局部不良组织反应的病例，这2例患者在单阶段翻修手术中接受了模块化部件置换治疗。
