The number of hip revision surgeries is expected to increase in recent years, and reconstruction of acetabular defects is a challenge for joint surgeons. The principle of reconstruction of acetabular defects is to achieve initial and long-term stability between the prosthesis and the host bone. With the development of surgical techniques, prosthetic materials, and revision concepts, there is an urgent need for new acetabular bone defect evaluation systems to meet clinical needs. The uncemented porous hemispherical cup has become the main prosthesis in clinical application, and metal augments are gradually replacing the structural allograft. Modular reconstruction combined cups and augments has shown favorable clinical results, which can be used for large acetabular defects with acetabular distraction technique, such as pelvic discontinuity. The advantages and disadvantages of impaction bone grafting, jumbo cups, metal augments, acetabular reinforcement rings, custom components (including custom triflanged acetabular components), and acetabular distraction technique still need to be observed in long-term follow-up.
近年来，髋关节翻修手术的数量预计会增加，髋臼缺损的重建对关节外科医生来说是一项挑战。髋臼缺损重建的原则是在假体与宿主骨之间实现初始和长期的稳定性。随着手术技术、假体材料和翻修理念的发展，迫切需要新的髋臼骨缺损评估系统以满足临床需求。非骨水泥型多孔半球形髋臼杯已成为临床应用中的主要假体，金属垫块正逐渐取代结构性同种异体骨移植。模块化重建组合髋臼杯和垫块已显示出良好的临床效果，可用于采用髋臼撑开技术的大型髋臼缺损，如骨盆连续性中断。打压植骨、超大号髋臼杯、金属垫块、髋臼加强环、定制部件（包括定制三叶髋臼部件）以及髋臼撑开技术的优缺点仍需长期随访观察。
