Ceramics are used in total hip arthroplasty due to inherent wettability and low wear rates, but fracture risk is a known complication. Rates as high as 13.4% were reported in the past, yet as low as 0.02% in newer generations. Howard et al. reported a fracture rate of 0.009% for fourth-generation ceramic heads. We present a case report of a 69-year-old male with a BMI of 40.01 kg/m who suffered a fracture of a 36-mm ceramic femoral head with pseudoacetabular involvement of the polyethylene liner. This occurred 2 years and 3 months after his primary surgery after a 4-foot fall off of a ladder. The patient underwent revision of his total hip arthroplasty with arthroplasty of the polyethylene liner and femoral head component without stem explantation.
由于陶瓷具有固有的润湿性和低磨损率，因此被用于全髋关节置换术，但骨折风险是一种已知的并发症。过去报道的骨折率高达13.4%，而新一代的骨折率则低至0.02%。霍华德等人报告第四代陶瓷股骨头的骨折率为0.009%。我们报告一例病例，一名69岁男性，体重指数为40.01kg/m，其36mm陶瓷股骨头发生骨折，聚乙烯衬垫累及假髋臼。这发生在他初次手术后2年零3个月，当时他从4英尺高的梯子上摔下。患者接受了全髋关节置换术翻修，更换了聚乙烯衬垫和股骨头组件，未取出股骨柄。
