Bilateral arthrography of the hip was performed in thirty-seven patients with unilateral Legg-Calvé-Perthes disease. Measurements made on the plain roentgenograms and on the arthrograms of the diameter of the femoral head, the width of the medial joint space, and the thickness of the acetabular cartilage were compared. The acetabulum-head quotients also were calculated. When present, evidence of flattening of the femoral head cartilage and of pooling of the contrast material also was noted. These data showed that in the early stages of Legg-Calvé-Perthes disease the articular cartilage is thickened, and that the cartilaginous femoral head is deformed and protrudes from the acetabulum. Arthrograms made with the hip in different positions also indicated the extent and location of collapse of the (osteochondroal) femoral head and therefore proved useful as a means to determine the best therapeutic position of the hip to provide coverage of the head. In three patients with severe transient synovitis, thickening of the articular cartilage resembling that seen in Legg-Calvé-Perthes disease was demonstrated.
对37例单侧Legg-Calvé-Perthes病患者进行了双侧髋关节造影。比较了在普通X线片和关节造影上对股骨头直径、内侧关节间隙宽度以及髋臼软骨厚度的测量结果。还计算了髋臼-头商。如有股骨头软骨扁平及造影剂积聚的证据也予以记录。这些数据表明，在Legg-Calvé-Perthes病的早期，关节软骨增厚，股骨头软骨变形并从髋臼突出。在髋关节处于不同位置时进行的关节造影也显示了（骨软骨性）股骨头塌陷的程度和位置，因此证明作为确定髋关节最佳治疗位置以覆盖股骨头的一种方法是有用的。在3例严重短暂性滑膜炎患者中，发现了类似于Legg-Calvé-Perthes病所见的关节软骨增厚。
