Clinical results after total hip arthroplasty with the use of a Hylamer liner have been described as being poor. In this study, polyethylene wear rates as well as clinical results were assessed after hip arthroplasty using a Hylamer liner. Thirty patients were followed radiographically and clinically after total hip arthroplasty with a Hylamer liner. The mean follow-up was six years. Radiolucent lines and wear rates were evaluated in correlation to different parameters and clinical scores. Radiolucent zones were found in 40% of the femoral and 27% of the acetabular components. Wear rates showed no correlation to the clinical scores, nor to other parameters. The SF-36 questionnaire showed inferior results compared to healthy controls. These findings confirm the poor results described with Hylamer in current literature. A significant influence of the different patient or prosthesis specific parameters on the survival of the prosthesis could not be confirmed.
使用Hylamer内衬进行全髋关节置换术后的临床结果一直被描述为较差。在本研究中，评估了使用Hylamer内衬进行髋关节置换术后的聚乙烯磨损率以及临床结果。30例患者在使用Hylamer内衬进行全髋关节置换术后接受了影像学和临床随访。平均随访时间为6年。评估了透亮线和磨损率与不同参数及临床评分的相关性。在40%的股骨组件和27%的髋臼组件中发现了透亮区。磨损率与临床评分及其他参数均无相关性。与健康对照组相比，SF-36问卷显示结果较差。这些发现证实了当前文献中描述的Hylamer的不良结果。未能证实不同患者或假体特定参数对假体生存率有显著影响。
