As the number of primary total hip arthroplasty (THA) procedures performed continues to rise, the burden of revision THA procedures is also expected to increase. Proper evaluation and management of acetabular bone loss at the time of revision surgery will be an increasing challenge facing orthopaedic surgeons. Proper preoperative patient assessment and detailed preoperative planning are essential in obtaining a good clinical result. Appropriate radiographs are critical in assessing acetabular bone loss, and specific classification schemes can identify bone loss patterns and guide available treatment options. Treatment options include impaction grafting and cementation of the acetabulum, noncemented hemispheric acetabular reconstruction, structural allograft reconstruction, noncemented reconstruction with modular porous metal augments, ring and cage reconstruction, oblong cup reconstruction, cup-cage reconstruction, and triflange reconstruction.
随着初次全髋关节置换术（THA）数量的不断增加，翻修 THA 手术的负担预计也会增加。在翻修手术时，正确评估和处理髋臼骨量丢失将是骨科医生面临的一个日益严峻的挑战。术前对患者进行适当的评估和详细的术前规划对于获得良好的临床效果至关重要。适当的影像学检查对于评估髋臼骨量丢失至关重要，而特定的分类方案可以确定骨量丢失的模式，并指导可用的治疗选择。治疗选择包括髋臼的打压植骨和骨水泥固定、非骨水泥半球形髋臼重建、结构性同种异体骨重建、带模块化多孔金属增强物的非骨水泥重建、环和笼重建、长椭圆形杯重建、杯笼重建和三叶形重建。
