INTRODUCTION
Revision rates of total hip arthoplasty have decreased after introducing total hip arthroplasty using ceramic component due to reduce wear and osteolysis.
CASE REPORT
29 year old male case of bilateral hip avascular necrosis operated for bilateral hip THA presented 30 months after with complaint of squeaking, x-ray showing left ceramic liner fracture without any history of trauma. Revision of ceramic liner and head with ceramic on polyethylene was done.
DISCUSSION AND CONCLUSION
Ceramic on ceramic articulation has the lowest wear rate among various articulations. However, there is a concern about ceramic implant fracture; therefore ceramic with polyethylene bearing could be a good choice.
引言
由于减少了磨损和骨溶解，采用陶瓷部件的全髋关节置换术后，全髋关节置换术的翻修率有所下降。
病例报告
一名29岁男性双侧髋关节缺血性坏死患者接受了双侧髋关节全髋关节置换术，术后30个月出现吱吱声，X线显示左陶瓷内衬骨折，无任何外伤史。对陶瓷内衬和股骨头进行了陶瓷对聚乙烯的翻修。
讨论与结论
陶瓷对陶瓷关节在各种关节中磨损率最低。然而，人们担心陶瓷植入物会骨折；因此，陶瓷对聚乙烯承重可能是一个不错的选择。
