The purpose of this study was to compare the results of revision total hip arthroplasty after fracture of primary ceramic components using different type of revision bearing surfaces.
We analysed the results of 16 patients with a follow-up more than 3 years after first revision. 6 were revised to ceramic-on-ceramic (CoC) bearing, 9 to metal-on-polyethylene (MoP) and 1 to ceramic-on-cross-linked polyethylene (CoXLP) bearing.
The mean follow-up was 87 months. Patients with revision to CoC had higher Harris Hip Score (HHS) of 89 points in comparison to the patients with revision to MoP with 84 points. Radiographic examinations revealed visible eccentric polyethylene wear with osteolysis in 3 out of 9 patients revised to MoP. There were no detrimental x-ray changes in patients revised to CoC components.
We consider CoC as the best option at revision operation for ceramic component fracture.
本研究旨在比较使用不同类型翻修关节面进行初次陶瓷部件骨折后全髋关节翻修术的结果。
我们分析了16例初次翻修术后随访超过3年患者的结果。其中6例翻修为陶瓷对陶瓷（CoC）关节面，9例翻修为金属对聚乙烯（MoP）关节面，1例翻修为陶瓷对交联聚乙烯（CoXLP）关节面。
平均随访时间为87个月。翻修为CoC关节面的患者Harris髋关节评分（HHS）较高，为89分，而翻修为MoP关节面的患者评分为84分。影像学检查显示，9例翻修为MoP关节面的患者中有3例出现明显的聚乙烯偏心磨损并伴有骨溶解。翻修为CoC部件的患者未出现有害的X线改变。
我们认为CoC是陶瓷部件骨折翻修手术的最佳选择。
