目的：应用磁共振成像技术评价Legg-Calvé-Perths病髋关节滑膜炎的程度和持续性，并将滑膜炎的程度与骨痂坏死的程度相关联。材料和方法：对72例(84个髋关节)患者的170个MRI图像进行检查。在冠状平面上进行T2加权成像，以评估髋关节滑膜炎症的程度。结果：所有病例均在病变早期发现滑膜炎症。在Catterall II组中，滑膜炎在诊断后6个月内表现为轻度至中度。坏死较严重的髋关节，Catterall组III和IV，有中度或重度滑膜炎。滑膜炎症程度与Herring等人的侧柱分类相关。此外，在MRI上，骨骺信号改变的程度与滑膜炎症的程度也有很好的相关性。当在T1或T2加权图像上评估信号变化时，两者没有差异。在诊断后30个月，Catterall第一组髋关节可以看到滑膜炎的迹象，在Catterall第二组和第三组髋关节中可以看到长达36个月的滑膜炎迹象，2例甚至更长时间。结论：MRI上滑膜炎症的程度与X线片或MRI所见的骨骺坏死程度有关，也与侧柱分类有关，即与临床预后不良有关。在Catterall IV组髋关节中，滑膜炎甚至可以在确诊后持续长达60个月
Purpose: to evaluate, by means of MR imaging, the degree and persistence of synovitis in the hip joint in Legg-Calvé-Perthes disease and to correlate the degree of synovitis with the degree of epiphyseal necrosis Material and Methods: A total of 170 MR images in 72 patients (84 hips) were examined. the T2-weighted MR images were taken in the coronal plane in order to evaluate the degree of synovitis in the hip joint Results: MR revealed synovitis in all cases in the early phase of the disease. in Catterall group II, synovitis was discreet to moderate for up to 6 months after diagnosis. Hips with more severe necrosis, Catterall groups III and IV, had moderate or intense degrees of synovitis. There was a correlation between the degree of synovitis and the lateral pillar classification according to HERRING et al. Also, there was a good correlation between the extent of signal changes in the epiphysis on MR imaging and the degree of synovitis. There was no difference when signal changes were evaluated on T1- or T2-weighted images. Signs of synovitis could be seen for up to 30 months after diagnosis in Catterall group I hips, and in Catterall groups II and III for up to 36 months, and in 2 cases even longer. Some Catterall group IV hips had discreet or mild synovitis for 60 months or more, after diagnosis Conclusion: the degree of synovitis on MR imaging correlates to the extent of epiphyseal necrosis seen on radiographs or MR imaging as well as to the lateral pillar classification, i.e. to a poor clinical outcome. in Catterall group IV hips, synovitis can even persist for up to 60 months after diagnosis
