Twenty patients with 23 painful total hip prostheses were examined by radionuclide imaging (20 cases), arthrography (11 cases), needle aspiration (9 cases), and surgery (19 cases) for the purpose of assessing loosening and/or infection. Bone imaging was most accurate, showing three main distributions of activity: (a) ectopic calcification, (b) focal increased activity at the upper and lower ends of the femoral prosthesis, and (c) diffuse activity. These findings suggest that infection and loosening can be differentiated in many instances. None of the patients with focal activity had infection, compared to 2 of the 3 patients with diffuse uptake.
为评估松动和/或感染情况，对20例患有23个疼痛性全髋关节假体的患者进行了放射性核素成像检查（20例）、关节造影（11例）、穿刺抽吸（9例）和手术（19例）。骨成像最为准确，显示出三种主要的活性分布：(a) 异位钙化，(b) 股骨假体上下端的局灶性活性增加，以及(c) 弥漫性活性。这些发现表明，在许多情况下感染和松动是可以区分的。有局灶性活性的患者均无感染，而在有弥漫性摄取的3例患者中有2例感染。
