BACKGROUND
The addition of junctions in modular stems implies a greater susceptibility to corrosion.
PURPOSE
The aim of this study is to compare serum chromium and cobalt levels after using a bimodular stem and its monoblock counterpart in primary total hip arthroplasty. Postoperative clinical scores were also compared.
PATIENTS AND METHODS
A prospective cohort study between 2012 and 2015 was designed. One arm of the cohort included patients with the cementless modular neck stem H-Max M® and the other with the cementless monoblock stem counterpart H-Max S®.
RESULTS
No statistically significant difference was found in chromium value between groups (p = 0.621) at two years postoperative. Cobalt value was higher in the modular group (p = < 0.001). No statistically significant difference was found in clinical postoperative scores except for the Harris Hip Score, with better results at six months in modular group (p = 0.007).
CONCLUSIONS
Higher serum cobalt level in the modular group has limited the use of modular stems in our daily practice. Advantages of modular stem were not found.
LEVEL OF EVIDENCE

背景
在模块化干骺端中增加连接点意味着更容易发生腐蚀。
目的
本研究的目的是比较初次全髋关节置换中使用双模块化干骺端和其一体式对应物后血清铬和钴水平。还比较了术后临床评分。
患者和方法
设计了 2012 年至 2015 年的前瞻性队列研究。队列的一组包括使用非骨水泥模块化颈干 H-Max M®的患者，另一组则为使用非骨水泥一体式对应物 H-Max S®的患者。
结果
在两年的术后随访中，两组之间的铬值没有统计学上的显著差异（p=0.621）。在模块化组中钴值更高（p<0.001）。除了 Harris 髋关节评分外，术后临床评分没有统计学上的显著差异，在模块化组中六个月时结果更好（p=0.007）。
结论
模块化组中血清钴水平较高，限制了我们在日常实践中使用模块化干骺端。没有发现模块化干骺端的优势。
