UNASSIGNED: A 63-year-old male underwent THA utilizing a femoral stem with a mixed-metal modular femoral neck. After the stem was voluntarily recalled, he was indicated to be monitored for manifestations ofmodular junction corrosion and development of adverse local tissue reactions (ALTR). An association between activity levels and serial serum cobalt levels was demonstrated.
UNASSIGNED: In this patient with a THA incorporating a mixed-metal modular femoral neck, modification of activity intensity may have played a role in altered corrosion generation, as indicated by serum metal ion levels. In turn, this may play a role in the progression of ALTR.
■一名63岁男性使用混合金属模块化股骨颈的股骨柄接受了THA。在茎被自愿召回后,患者被指示接受模块化接头腐蚀的表现和不良局部组织反应(ALTR)的发展监测.证明了活性水平与系列血清钴水平之间的关联。
■在这位合并混合金属模块化股骨颈的THA患者中,活动强度的改变可能在腐蚀产生的改变中发挥作用,如血清金属离子水平所示。反过来,这可能在ALTR的进展中起作用.
