Between 1988 and 2002, 47 patients (50 hips) were treated with acetabular shell augmentation arthroplasty for recurrent idiopathic dislocation of their total hip arthroplasty. Apparent causes for dislocation such as deep infection, component malposition, or polyethylene wear were excluded. Follow-up averaged 74 months (range, 12-178 months), and clinically, 30 hips (60%) did not present a subsequent dislocation at most recent follow-up. In five hips (10%), deep infection after the augmentation procedure necessitated removal of the entire prosthesis. In our opinion, this technique cannot be recommended as it has an unacceptable failure and high infection rate.
1988年至2002年间，47例患者（50髋）因全髋关节置换术后复发性特发性脱位接受髋臼杯增强关节成形术治疗。排除了诸如深部感染、假体位置不当或聚乙烯磨损等明显的脱位原因。随访平均74个月（范围12 - 178个月），临床上，30髋（60%）在最近一次随访时未出现再次脱位。5髋（10%）在增强手术后发生深部感染，需要取出整个假体。我们认为，该技术不可推荐，因为其失败率和感染率令人无法接受。
