Acetabular revision is probably the most difficult aspect of hip reconstructive surgery. Although the majority of acetabular revisions can be performed using an uncemented hemispherical acetabular device with ancillary fixation, patients with severe acetabular deficiencies and poor bone quality require more complex alternatives for revision. The limitations of traditional cementless acetabular implants has promoted the development of improved methods of fixation and revision techniques. Highly porous metals have been introduced for clinical use in arthroplasty surgery over the last decade. Their higher porosity and surface friction are ideal for acetabular revision, optimising biological fixation. The use of trabecular metal cups in acetabular revision has yielded excellent clinical results.
This review focuses on the use of cementless implants for acetabular revision. The use of trabecular metal cups, augments, jumbo cups, oblong cups, cages, and structural grafting are also discussed.
髋臼翻修可能是髋关节重建手术中最具挑战性的部分。虽然大多数髋臼翻修可以使用非骨水泥半球形髋臼装置和辅助固定来完成，但对于严重髋臼缺损和骨质量差的患者，需要更复杂的替代方案来进行翻修。传统非骨水泥髋臼植入物的局限性促进了固定和翻修技术的改进方法的发展。过去十年中，高多孔金属已被引入关节置换手术中用于临床应用。它们更高的多孔性和表面摩擦力非常适合髋臼翻修，优化了生物固定。在髋臼翻修中使用小梁金属杯已取得了优异的临床效果。
本文重点介绍了非骨水泥植入物在髋臼翻修中的应用。还讨论了小梁金属杯、加强环、巨型杯、长形杯、笼和结构性移植物的使用。
