We compared the rate of revision for instability after total hip replacement (THR) when lipped and non-lipped acetabular liners were used. We hypothesised that the use of a lipped liner in a modular uncemented acetabular component reduces the risk of revision for instability after primary THR. Using data from the New Zealand Joint Registry, we found that the use of a lipped liner was associated with a significantly decreased rate of revision for instability and for all other indications. Adjusting for the size of the femoral head, the surgical approach and the age and gender of the patient, this difference remained strongly significant (p < 0.001). We conclude that evidence from the New Zealand registry suggests that the use of lipped liners with modular uncemented acetabular components is associated with a decreased rate of revision for instability after primary THR.
我们比较了使用带唇和不带唇髋臼衬垫的全髋关节置换术（THR）后不稳定的翻修率。我们假设在模块化非骨水泥髋臼组件中使用带唇衬垫可以降低初次 THR 后不稳定的翻修风险。利用来自新西兰关节登记处的数据，我们发现使用带唇衬垫与不稳定和所有其他适应证的翻修率显著降低相关。在调整了股骨头大小、手术入路以及患者的年龄和性别后，这种差异仍然具有统计学意义（p < 0.001）。我们得出结论，来自新西兰登记处的证据表明，在模块化非骨水泥髋臼组件中使用带唇衬垫与初次 THR 后不稳定的翻修率降低相关。
