A radiological scoring system was developed to identify grades of loosening of the components of a cemented hip replacement. In grade 1, there are mild changes, usually of minor significance; in grade 2 moderate changes which need regular observation, and in grade 3 severe changes which indicate impending failure. Three parameters are used for the socket, giving a score of 10 points, and 5 for the stem, with a score of 15 points. This method can be used to provide a comparison between different series with a long-term follow up.
开发了一种放射学评分系统，以确定骨水泥型髋关节置换组件的松动程度。1级为轻度变化，通常意义不大；2级为中度变化，需要定期观察；3级为严重变化，表明即将发生故障。髋臼使用三个参数，满分为10分，股骨柄为5分，总分为15分。该方法可用于对不同系列进行长期随访比较。
