Contrast arthrography, radionuclide arthrography, scintigraphy and roentgen stereophotogrammetric analysis (RSA) were used to detect mechanical loosening in 14 painful total hip replacements. All prosthetic components unstable by RSA, or with abnormal arthrogram, or with increased scintigraphic activity, or loose at revision were migrating, but no non-migrating components demonstrated any of these signs of loosening. Our findings indicate that mechanical loosening should be defined as migration.
采用关节造影、放射性核素关节造影、闪烁扫描法及X线立体摄影测量分析（RSA）对14例疼痛性全髋关节置换术患者进行机械性松动检测。所有经RSA判定为不稳定、或关节造影异常、或闪烁扫描活性增加、或翻修时发现松动的假体部件均有移位，但无移位的部件未表现出任何这些松动迹象。我们的研究结果表明，机械性松动应定义为移位。
