Several studies have discussed trunnionosis in metal-on-metal total hip arthroplasties. However, trunnionosis in metal-on-polyethylene total hip arthroplasties has been less frequently discussed.
In this study, trunnionosis in two male patients undergoing metal-on-polyethylene total hip arthroplasty, which was done to treat femoral head osteonecrosis were reported and discussed adequately.
Total hip arthroplasties (THA) were done for the treatment of femoral head osteonecrosis in these cases. In the first case, trunnionosis occurred one year after the revision of the primary THA, and in the second case occurred ten years after the primary THA. Both of these cases were presented with reduced range of motion. After surgery, the symptoms were resolved, and the patients remained complication-free until the last follow-up.
This report raises awareness regarding the importance of trunnionosis as a serious complication of modular total hip arthroplasty.
多项研究探讨了金属对金属全髋关节置换术中的柄部腐蚀问题。然而，金属对聚乙烯全髋关节置换术中的柄部腐蚀问题较少被讨论。
在本研究中，报告并充分讨论了两名接受金属对聚乙烯全髋关节置换术以治疗股骨头坏死的男性患者的柄部腐蚀情况。
这些病例均进行全髋关节置换术以治疗股骨头坏死。在第一例中，柄部腐蚀发生在初次全髋关节置换术翻修术后一年，在第二例中发生在初次全髋关节置换术后十年。这两例均表现为活动范围减小。手术后，症状得到缓解，患者直至最后一次随访均无并发症。
本报告提高了人们对柄部腐蚀作为模块化全髋关节置换术严重并发症的重要性的认识。
