Long-term outcomes of cemented and uncemented cups were compared in patients with hip dysplasia who had undergone revision hip arthroplasty. Patients had uncontained superolateral acetabular defects reconstructed with a structural allograft. This retrospective study compared 18 cemented acetabular cups to 27 uncemented acetabular cups. Average follow-up was 216 months (range, 96-312). Nineteen acetabular cups (42%) failed due to loosening and were revised. The 10- and 20-year cup survival was 88% and 76% in the uncemented group and 67% and 36% in the cemented group. Log rank analysis showed this difference to be significant (P = .0077). Uncemented acetabular cups performed significantly better than cemented cups.
比较了髋关节发育不良患者行髋关节翻修术后使用骨水泥固定和非骨水泥固定髋臼杯的长期疗效。患者均存在外侧壁结构性骨缺损，使用结构性同种异体骨进行重建。该回顾性研究比较了 18 例骨水泥固定髋臼杯和 27 例非骨水泥固定髋臼杯。平均随访 216 个月（96-312 个月）。19 例髋臼杯（42%）因松动而失败并进行了翻修。非骨水泥组 10 年和 20 年的髋臼杯生存率为 88%和 76%，骨水泥组分别为 67%和 36%。对数秩分析显示这种差异有统计学意义（P =.0077）。非骨水泥髋臼杯的性能明显优于骨水泥髋臼杯。
