Magnetic resonance (MR) imaging studies were obtained to evaluate the shape of the cartilaginous femoral head and the adequacy of femoral acetabular containment in 35 children with Legg-Calvé-Perthes disease (LCPD). MR results for 24 of the 35 children were compared with results at arthrography. The shape of the cartilaginous femoral head was well identified with MR imaging, but, with arthrography, less information could be obtained about the medial and lateral aspects of the cartilaginous capital epiphyses in nine and three cases, respectively. Thirteen children underwent surgery; remodeling and regained femoroacetabular congruity of the articular surfaces following derotation varus osteotomy was identified in seven of 10 who underwent repeat MR imaging. In addition, MR images and conventional radiographs of the hips were compared. The radiographically identifiable distribution of the bone necrosis of the capital epiphysis correlated well with that demonstrated on MR images. MR imaging is a valuable non-invasive procedure with which to obtain information about the status and treatment of the cartilaginous femoral head in children with LCPD.
对35例患有Legg-Calvé-Perthes病（LCPD）的儿童进行了磁共振（MR）成像研究，以评估股骨头软骨的形状以及股骨髋臼包容情况。将35例儿童中的24例的MR结果与关节造影结果进行了比较。通过MR成像可以很好地识别股骨头软骨的形状，但在关节造影中，分别有9例和3例关于软骨性股骨头骨骺内侧和外侧方面的信息较少。13名儿童接受了手术；在接受重复MR成像的10名儿童中，有7名在旋转内翻截骨术后关节面重塑并恢复了股骨髋臼的一致性。此外，还比较了髋关节的MR图像和传统X线片。X线片上可识别的股骨头骨骺骨坏死分布与MR图像上显示的情况相关性良好。MR成像是一种有价值的非侵入性检查方法，可用于获取有关LCPD儿童股骨头软骨状况和治疗的信息。
