Fractures of the ceramic ball in total hip arthroplasty are an uncommon cause of arthroplasty failure, and reports of this complication in ceramic-on-polyethylene total hip arthroplasty articulations are rare. Ball fractures have been reported in patients who were overweight, had high levels of activity, or had been injured. Other postulated contributory factors have included small ball diameter, defects in ceramic quality or manufacture, and errors in implantation of the arthroplasty. A case of a ceramic ball fracture in a ceramic and polyethylene articulation is reported, and the literature on such fractures is reviewed.
全髋关节置换术中陶瓷球骨折是关节置换失败的罕见原因，关于陶瓷对聚乙烯全髋关节置换关节中这种并发症的报道很少。已有超重、活动量高或受过伤的患者出现球部骨折的报道。其他推测的促成因素包括小球直径、陶瓷质量或制造缺陷以及关节置换植入错误。本文报告了一例陶瓷与聚乙烯关节中陶瓷球骨折的病例，并对有关此类骨折的文献进行了综述。
