Twenty-two patients with severe pain in the hip on weight-bearing after prosthetic replacement were investigated by radiography, arthrography, scintigraphy and ultrasonography to determine the accuracy of these diagnostic methods in detecting loosening of infective or mechanical origin. In two cases, ultrasonography revealed superficial infections that were resolved with antibiotic therapy. Of the remaining 20 cases, 12 involved a deep infection and in 8 the loosening was of mechanical origin. In the deep infections, standard radiography provided a diagnosis in 66% of cases, arthrography in 75% and scintigraphy in 83%, while ultrasonography detected the deep infection in all 12 cases. In the patients with mechanical mobilization, arthrography and ultrasonography were 100% accurate. Since ultrasonography is able to detect discrete or diffuse lesion of the soft tissues around a prosthesis it should be included among the methods used to screen patients with painful hips after prosthetic replacement.
对22例人工关节置换术后负重时髋部剧痛的患者进行了X线摄影、关节造影、闪烁扫描和超声检查，以确定这些诊断方法在检测感染性或机械性松动方面的准确性。2例患者经超声检查发现浅表感染，经抗生素治疗后痊愈。其余20例中，12例为深部感染，8例为机械性松动。在深部感染病例中，标准X线摄影诊断出66%的病例，关节造影诊断出75%的病例，闪烁扫描诊断出83%的病例，而超声检查在所有12例深部感染病例中均检测到感染。在机械性松动的患者中，关节造影和超声检查的准确率为100%。由于超声检查能够检测假体周围软组织的离散或弥漫性病变，因此应将其纳入用于筛查人工关节置换术后髋部疼痛患者的方法之中。
