Atraumatic ceramic femoral head fracture is an uncommon but overwhelming complication of total hip arthroplasty (THA). The complication rate is low, with few reports in the literature. It is critical to continue researching late fracture risk to mitigate these instances.
A 68-year-old Caucasian female presented with an atraumatic ceramic femoral head fracture in the setting of a ceramic-on-ceramic THA 17 years after primary surgery. The patient was successfully revised to a dual-mobility construct with a ceramic femoral head and a highly cross-linked polyethylene liner. The patient returned to normal function without pain.
The complication rate for fracture of the ceramic femoral head is as low as 0.001% for fourth-generation aluminum matrix composite designs, while the complication rate of late atraumatic ceramic fracture is largely unknown. We present this case to add to the current literature.
无创伤性陶瓷股骨头骨折是全髋关节置换术(THA)一种不常见但后果严重的并发症。其并发症发生率较低,文献报道较少。持续研究晚期骨折风险对于减少此类情况至关重要。
一名68岁的白种女性在初次手术后17年的陶瓷对陶瓷全髋关节置换术中出现无创伤性陶瓷股骨头骨折。患者成功翻修为采用陶瓷股骨头和高度交联聚乙烯内衬的双动结构。患者恢复正常功能且无疼痛。
对于第四代铝基复合材料设计,陶瓷股骨头骨折的并发症发生率低至0.001%,而晚期无创伤性陶瓷骨折的并发症发生率在很大程度上尚不清楚。我们报告此病例以丰富当前文献。
