The aim of this study was to analyze dual mobility cup survival rate on young patients under 50 years old at more than 20 years of follow up.
One hundred thirty seven hips with a first generation of dual mobility Bousquet cup (Serf) were included. The mean age at the time of the surgery was 41 years and the mean follow-up was 21.9 years.
Twenty year follow-up cup survival rate was 77%. No dislocation occurred, 44 hips were revised (including 21 cup aseptic loosenings isolated, 15 Intra Prosthetic Dislocations), seven hips were lost to follow-up, 11 patients died, and 75 hips were still in situ.
First generation dual mobility cup survival on young patient was comparable with literature results. The main complications, cup aseptic loosening and intra prosthetic dislocation, were wear-related. With improvements of the defects of first generation dual mobility, we might expect an even better survival rate with contemporary DM cups.
本研究旨在分析20多年随访期内50岁以下年轻患者双动髋臼杯的生存率。
纳入137例使用第一代双动Bousquet髋臼杯（Serf）的髋关节。手术时的平均年龄为41岁，平均随访时间为21.9年。
20年随访期髋臼杯生存率为77%。未发生脱位，44例髋关节进行了翻修（包括21例孤立的髋臼无菌性松动、15例人工关节内脱位），7例髋关节失访，11例患者死亡，75例髋关节仍在位。
第一代双动髋臼杯在年轻患者中的生存率与文献结果相当。主要并发症，即髋臼无菌性松动和人工关节内脱位，与磨损有关。随着第一代双动髋臼杯缺陷的改进，我们可能预期当代双动髋臼杯的生存率会更高。
