A retrospective study was performed to determine the accuracy of 99mTc-methylene diphosphonate bone imaging in the evaluation of total hip arthrosplasty for lossening and/or infection. Using focally increased activity at the tip of the femoral component or in the region of the acetabular component as a criterion, the examination was 77% specific and 100% sensitive for loosening and/or infection. A possible explanation for the increased uptake at the tip of the femoral component and the role of this examination in the management of a painful total hip prosthesis are discussed.
进行了一项回顾性研究，以确定99mTc-亚甲基二膦酸盐骨显像在评估全髋关节置换术松动和/或感染方面的准确性。以股骨部件尖端或髋臼部件区域的局部活性增加为标准，该检查对松动和/或感染的特异性为77%，敏感性为100%。文中讨论了股骨部件尖端摄取增加的可能原因以及该检查在疼痛性全髋关节假体处理中的作用。
