The aim of this article is to show a new concept of indication and application of the MUTARS RS Cup System in primary and revision hip arthroplasty. This integrated system is applicable for different acetabular cup replacements in patients with acetabular fractures or instable defects, as well as periprosthetic acetabular fractures. The MUTARS RS Cup System is a cementless revision cup for insertion into the acetabulum with an integrated polyethylene cup, which fits to a regular or bipolar head. This system replaces the conventional approach for acetabular revision with a Burch-Schneider ring, in which a normal polyethylene cup is cemented. This interface with its complications is avoided with this system of a titanium revision cup with integrated polyethylene cup. Steps of preoperative planning and the intraoperative implementation will be highlighted in this article.
This system was applied in 49 patients with 52 MUTARS RS Cup Implantations in 30 males, 22 females, with an average age of 76,1 years (36,9-94,4 years).
The system shows a good operative feasibility, as well as a reliable handling and safe method for stable treatment of non-reconstructable acetabular fractures or acetabular incongruencies and instabilities.
本文旨在展示 MUTARS RS 杯系统在初次和翻修髋关节置换术中的新适应证和应用概念。该一体化系统适用于髋臼骨折或不稳定缺损患者以及髋关节假体周围骨折的不同髋臼杯置换。MUTARS RS 杯系统是一种非骨水泥翻修杯，可插入髋臼，带有集成的聚乙烯杯，适合常规或双极头。与传统的髋臼翻修方法（即用 Burch-Schneider 环固定普通聚乙烯杯）相比，该系统避免了这种钛制翻修杯与集成聚乙烯杯的界面及其相关并发症。本文将重点介绍术前规划和术中实施的步骤。
该系统应用于 49 例患者（30 名男性，22 名女性）的 52 例 MUTARS RS 杯植入术，平均年龄 76.1 岁（36.9-94.4 岁）。
该系统具有良好的手术可行性，以及可靠的操作和安全的方法，可稳定治疗不可重建的髋臼骨折或髋臼错位和不稳定。
