The first aim of this study was to evaluate whether preoperative renal function is associated with postoperative changes in whole blood levels of metal ions in patients who have undergone a Birmingham Hip Resurfacing (BHR) arthroplasty with a metal-on-metal bearing. The second aim was to evaluate whether exposure to increased cobalt (Co) and chromium (Cr) levels for ten years adversely affected renal function.

单侧伯明翰髋关节表面置换术后的金属水平和肾小球滤过率。

本研究的首要目的是评估接受金属对金属轴承伯明翰髋关节表面置换 (BHR) 关节置换术的患者术前肾功能是否与术后全血金属离子水平变化相关。第二个目的是评估十年内暴露于升高的钴 (Co) 和铬 (Cr) 水平是否会对肾功能产生不利影响。
