99mTc-MDP-scintimetry was performed in 25 consecutive cases of radiographically silent transient synovitis of the hip in children. Fourteen cases had normal scintimetry; seven cases had an increased uptake in the epiphysis; four cases had markedly defective uptake in the epiphysis, indicating interrupted vascular supply. At repeat scintimetry 6 weeks later, the uptake was normal or increased in three of these four cases; the one case with a persistent defect was the only case in this series who later developed radiographic evidence of Legg-Calvé-Perthes' disease. In some cases presenting with clinical symptoms of synovitis of the hip, there is a transient, spontaneously recovering ischaemia of the proximal femoral epiphysis, not followed by radiographic evidence of necrosis. This should be considered in attempts to make a pre-radiographic diagnosis of Legg-Calvé-Perthes' disease by radionuclide methods.
对连续25例X线片显示为髋关节隐性短暂滑膜炎的儿童进行了99m锝-亚甲基二膦酸盐闪烁扫描检查。14例闪烁扫描结果正常；7例骨骺摄取增加；4例骨骺摄取明显缺损，提示血管供应中断。在6周后复查闪烁扫描时，这4例中的3例摄取正常或增加；唯一持续存在缺损的病例是该系列中后来出现Legg-Calvé-Perthes病X线证据的唯一病例。在一些表现为髋关节滑膜炎临床症状的病例中，存在股骨近端骨骺短暂的、可自发恢复的缺血，且未出现坏死的X线证据。在试图通过放射性核素方法对Legg-Calvé-Perthes病进行X线前期诊断时应考虑到这一点。
