Twenty-three children with Legg-Calvé-Perthes disease were examined to determine the femoral head shape. We evaluated and correlated conventional radiography, arthrography and MR imaging. In the a.p. view, measurements were obtained from the center of the femoral head along the bony or cartilaginous outline at 30 degrees intervals. Maximum flattening of the cartilaginous outline appeared laterally, 60 degrees from the center of the baseline of the epiphyseal index and the caput index. Maximum flattening of the bony outline was found at 75 degrees. Arthrography and MR imaging gave the same information about the shape of the femoral head cartilage. The bony femoral head shape on conventional radiographs in the a.p. view did not reflect the cartilage shape obtained by MR and arthrography.
对23例Legg-Calvé-Perthes病患儿进行检查以确定股骨头形状。我们对传统X线摄影、关节造影和磁共振成像进行了评估并相互关联。在前后位视图中，从股骨头中心沿骨或软骨轮廓每隔30度进行测量。软骨轮廓的最大扁平出现在外侧，与骨骺指数和头指数基线中心成60度角处。骨轮廓的最大扁平出现在75度处。关节造影和磁共振成像提供了关于股骨头软骨形状的相同信息。前后位视图中传统X线片上的股骨头骨形状并未反映出通过磁共振成像和关节造影获得的软骨形状。
