Twenty-two painful hip prostheses were studied prospectively with plain radiography, aspiration and arthrography, Tc-99m phosphate bone imaging, and gallium imaging to evaluate loosening, infection, or both and to compare the accuracy of these modalities. Fifteen prostheses were revised yielding 14 loose femoral and eight loose acetabular components. Five proved to have infected prostheses. Arthrograms, plain radiographs, and bone scans are highly sensitive in detecting loosening of the femoral component. This study confirmed a previous retrospective study in demonstrating that accuracy of diagnosis of an abnormal acetabular component using all four modalities is less than that for the femoral component. In infected prostheses, phosphate bone imaging showed high sensitivity of a pattern that accurately diagnosed all the infected cases, whereas gallium imaging missed one case.
对22例疼痛性髋关节假体进行了前瞻性研究，采用普通X线摄影、抽吸和关节造影、锝-99m磷酸盐骨显像和镓显像，以评估假体松动、感染或两者情况，并比较这些检查方法的准确性。15例假体进行了翻修，其中14个股骨部件和8个髋臼部件松动。5例被证实为感染性假体。关节造影、普通X线片和骨扫描在检测股骨部件松动方面高度敏感。本研究证实了先前的一项回顾性研究，即使用所有四种检查方法诊断髋臼部件异常的准确性低于股骨部件。在感染性假体中，磷酸盐骨显像显示出一种模式的高敏感性，该模式准确诊断了所有感染病例，而镓显像漏诊了1例。
