A scoring system to determine radiological loosening in cemented total hip arthroplasty.
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.
