The evaluation of a painful hip prosthesis for suspected loosening frequently requires a multi-modality approach. Radionuclide arthroscintigraphy is a valuable adjunct to contrast arthrography, demonstrating greater sensitivity than contrast arthrography in detecting loosening of the femoral component of the prosthesis. Despite its reliability in the evaluation of cemented hip prostheses, the value of arthroscintigraphy in patients with uncemented or porous-coated prostheses is undetermined. The case of a false-positive radionuclide arthroscintigram in a patient with an uncemented prosthesis is reported. The literature is briefly examined, and the potential implications regarding interpretation of arthroscintigraphy in patients with porous-coated prostheses are discussed.
对于疑似松动的疼痛性髋关节假体进行评估通常需要采用多模态方法。放射性核素关节闪烁显像术是关节造影的一种有价值的辅助手段，在检测假体股骨部件松动方面比关节造影具有更高的灵敏度。尽管放射性核素关节闪烁显像术在评估骨水泥型髋关节假体方面具有可靠性，但其在非骨水泥型或多孔涂层假体患者中的价值尚不确定。本文报道了一例非骨水泥型假体患者放射性核素关节闪烁显像假阳性的病例。对相关文献进行了简要回顾，并讨论了多孔涂层假体患者关节闪烁显像解释方面的潜在影响。
