Abstract：
UNASSIGNED: Femoral neck modularity in total hip arthroplasty (THA) affords the surgeon the ability to optimize femoral neck length, offset, and version, thereby theoretically improving restoration of patient anatomy and biomechanics. The effect of activity on serum metal ion levels in patients with a THA with a mixed-metal modular neck design has not yet been described.
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.

摘要：
■全髋关节置换术（THA）中的股骨颈模块化为外科医生提供了优化股骨颈长度的能力，偏移,和版本,从而在理论上改善患者解剖结构和生物力学的恢复。尚未描述活性对具有混合金属模块化颈部设计的THA患者血清金属离子水平的影响。
■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.
