The aim of this investigation was to analyze the midterm results obtained with the metaphyseal fixation principle of the thrust plate prosthesis (TPP). Survival of 214 implants in 204 patients was analyzed. Clinical (Harris hip score) and radiologic examinations were carried out on 157 of 190 TPP with a postimplantation follow-up period of at least 5 years. Failure rate was 7.0% (9 aseptic and 6 septic loosening). Harris hip score increased from 36.9 +/- 13.5 points preoperatively to 91.2 +/- 13.1 points at follow-up. Eleven TPPs showed radiolucent lines not indicating prosthetic loosening. Thrust plate prosthesis is not an alternative to stemmed endoprostheses. It may be rarely indicated in very young patients where, because of their age, several revision operations can be expected.
本研究的目的是分析采用推力板假体（TPP）干骺端固定原则所获得的中期结果。对204例患者的214枚植入物的存活情况进行了分析。对190枚TPP中的157枚进行了临床（Harris髋关节评分）和放射学检查，植入后的随访期至少为5年。失败率为7.0%（9例无菌性松动和6例感染性松动）。Harris髋关节评分从术前的36.9±13.5分提高到随访时的91.2±13.1分。11枚TPP显示有透亮线，但未提示假体松动。推力板假体并非带柄假体的替代方案。在非常年轻的患者中，由于其年龄原因可能需要进行多次翻修手术，这种情况下可能很少会使用该假体。
