氧化铝对氧化铝全髋关节置换术已经使用了 30 年，主要在欧洲。这种组合的理论优势体现在其卓越的滑动特性、极低的磨屑生成以及足够的断裂韧性。如果材料控制得当，具有高密度、高纯度和小晶粒，就能实现这些优点。作者总结了陶瓷/陶瓷全髋关节置换术获得的结果。提供了有关磨损碎片表征和定量的体内行为以及炎症反应的组织学组织检查的信息，除非氧化铝碎片与金属或水泥混合，否则不会遇到炎症反应。接受腔固定的修改改善了临床结果。凭借压接金属外壳和使用了 10 年的氧化铝衬里，效果非常出色，尤其是在年轻和活跃的人群中。目前，当必须对年轻且活跃的患者进行全髋关节置换术时，氧化铝对氧化铝似乎是最佳选择之一。
Alumina-on-alumina total hip arthroplasty has been used for 30 years, mainly in Europe. The theoretical advantages of this combination are represented by its remarkable sliding characteristics, its very low wear debris generation, and its sufficient fracture toughness. These advantages are achieved if the material is properly controlled with high density, high purity, and small grains. The authors summarize the results obtained with ceramic/ceramic total hip arthroplasty. Information is provided about in vivo behavior regarding wear debris characterization and quantification, and histological tissue examinations for inflammatory reactions, which were not encountered except when alumina debris was mixed with metal or cement. Modification of socket fixation resulted in improved clinical outcomes. With a press-fit metal shell and an alumina liner utilized for 10 years, the results are excellent especially in a young and active population. Alumina-on-alumina seems at the moment to be one of the best choices when a total hip arthroplasty has to be performed in young and active patients.
