Thanks to its high primary stability, the concept of threaded cups has gained wide acceptance. The aim of this study is to report the long-term results of the Wagner conical screw cup. Between January 1993 and December 1994, 212 conical screw cup were implanted; 118 implants were clinically and radiographically followed up after a mean of 12.1 years. The Merle d'Aubigné score improved from a preoperative mean of 8.8 to 16.6 postoperatively. Four revisions were performed for heterotopic ossification. Three revisions were done to treat deep infection. Two isolated cup revisions and three more complete total hip joint revisions were required due to aseptic loosening. The overall survival rate at 12 years in this study was 93.2% (110/118); for aseptic loosening alone it was 95.8% (113/118). The Wagner conical screw cup by yields very good long-term results.
由于其较高的初始稳定性,螺纹杯的概念已获得广泛认可。本研究的目的是报告瓦格纳锥形螺旋杯的长期结果。在1993年1月至1994年12月期间,植入了212个锥形螺旋杯;平均12.1年后,对118例植入物进行了临床和影像学随访。Merle d'Aubigné评分从术前平均8.8分提高到术后16.6分。因异位骨化进行了4次翻修。为治疗深部感染进行了3次翻修。由于无菌性松动,需要进行2次单独的髋臼翻修和另外3次全髋关节翻修。本研究中12年的总生存率为93.2%(110/118);仅无菌性松动的生存率为95.8%(113/118)。瓦格纳锥形螺旋杯产生了非常好的长期结果。
