The aim of this study was to evaluate our long-term results with the Alloclassic CSF screw cup total hip arthroplasty system. This is the first study to provide a 30-year follow-up, based upon our 30-year follow up study on the Alloclassic stem system.
We reviewed 178 Alloclassic CSF screw cup systems, implanted in 171 patients from 1986 to 1987. The Zweymüller stem family was used in all cases. 136 patients had died over the last 30 years, so twenty-nine out of 35 patients being still alive, with a mean follow-up of 29,46 years (SD 0,48), were contacted by telephone and evaluated radiologically and clinically. Our loss-to-follow up was 17,14%. The mean age at follow-up was 83,01 years (72,4-95,2; SD 6,86).
If the endpoint is defined as the removal of the cup for aseptic loosening (3 cases), the overall survival rate is 98,31%. If the endpoint is revision for any reason (27 cases), the survival rate is 84,83%. Eleven patients needed an exchange of head and liner. The mean time from implantation until change of head and liner was 21,44 years (SD 5,92).
After 30 years of monitoring we can state that the evaluated system is very reliable in primary and secondary THA.
本研究旨在评估我们使用Alloclassic CSF螺钉杯全髋关节置换系统的长期结果。这是第一项基于我们对Alloclassic柄系统的30年随访研究提供30年随访的研究。
我们回顾了1986年至1987年植入171例患者体内的178个Alloclassic CSF螺钉杯系统。所有病例均使用Zweymüller柄系列。在过去30年中，136例患者已死亡，因此对35例仍存活的患者中的29例进行了电话联系，并进行了放射学和临床评估。我们的失访率为17.14%。随访时的平均年龄为83.01岁（72.4 - 95.2岁；标准差6.86）。
如果将终点定义为因无菌性松动而取出髋臼杯（3例），则总体生存率为98.31%。如果将终点定义为因任何原因进行翻修（27例），则生存率为84.83%。11例患者需要更换股骨头和内衬。从植入到更换股骨头和内衬的平均时间为21.44年（标准差5.92）。
经过30年的监测，我们可以说所评估的系统在初次和二次全髋关节置换中非常可靠。
