Recurrent dislocations of hip replacements are a difficult challenge. One treatment option for recurrent dislocations is the use of a dual mobility cup. The aim of this study was to retrospective investigate the effect of dual mobility cups as a treatment for recurrent dislocations in a consecutive series. Materials and.
56 consecutive patients were revised in the period November 2000 to December 2010. The mean age at revision was 72 years (SD 11, range 37-92)) and median number of dislocations before revision surgery were 4 (IQR, 2-11). In all cases, revision was made with a Saturne dual mobility cup (Amplitude, Neyron, France). The mean follow-up period was 44 months (SD 30, range 0.1-119).
One patient (1.8%) experienced a re-dislocation. Three patients (5.3%) had to be revised. One due to disintegration between the femoral head and inner shell, one due to loosening of the acetabular component, and one due to infection. Harris Hip Score improved from a mean of 76 before index surgery to 87 within one year after index surgery.
This study advocates the use of a dual mobility cup for treatment of recurrent dislocations of THR. However, studies with a longer follow up are needed in order to evaluate implant survival.
髋关节置换术后复发性脱位是一项艰巨的挑战。复发性脱位的一种治疗选择是使用双动髋臼杯。本研究的目的是回顾性研究双动髋臼杯作为连续系列复发性脱位治疗方法的效果。材料与方法：2000年11月至2010年12月期间，对56例连续患者进行了翻修手术。翻修时的平均年龄为72岁（标准差11，范围37 - 92岁），翻修手术前脱位的中位数为4次（四分位间距，2 - 11次）。所有病例均使用Saturne双动髋臼杯（Amplitude，Neyron，法国）进行翻修。平均随访期为44个月（标准差30，范围0.1 - 119个月）。结果：1例患者（1.8%）发生再次脱位。3例患者（5.3%）不得不进行再次翻修。1例是由于股骨头与内杯之间解体，1例是由于髋臼假体松动，1例是由于感染。Harris髋关节评分从初次手术前的平均76分提高到初次手术后1年内的87分。结论：本研究提倡使用双动髋臼杯治疗全髋关节置换术后的复发性脱位。然而，需要进行更长时间随访的研究以评估植入物的生存率。
