In total hip arthroplasty ceramic bearings are liable to fracture. We present the case of an 82-year-old male with groin pain and an audible squeak 6 months post ceramic on ceramic hip arthroplasty. Initial plain radiography and examination under anaesthetic (EUA) were normal. Fluoroscopy with normal image exposure was also unremarkable. Over penetration of the image intensifier film demonstrated a fracture of the ceramic acetabular liner. The patient subsequently underwent a revision of both acetabular and femoral bearing surfaces.Displaced ceramic liner fractures are easy to identify with plain radiographs. We recommend the use of over penetration using image intensification as a technique to help identify subtle ceramic liner fractures. To our knowledge this has not been previously reported in the literature.
在全髋关节置换术中，陶瓷轴承容易发生骨折。我们报告一例82岁男性患者，在陶瓷对陶瓷髋关节置换术后6个月出现腹股沟疼痛并伴有可闻及的摩擦声。最初的X线平片和麻醉下检查（EUA）均正常。正常图像曝光的荧光透视检查也无异常。图像增强器胶片过度穿透显示陶瓷髋臼内衬骨折。该患者随后接受了髋臼和股骨轴承表面的翻修手术。移位的陶瓷内衬骨折通过X线平片很容易识别。我们建议使用图像增强技术进行过度穿透，作为一种有助于识别细微陶瓷内衬骨折的方法。据我们所知，此前文献中尚未有过此类报道。
