We evaluated plain radiographs and arthrograms of twenty-one children with active Legg-Calvé-Perthes disease in order to determine the value of the arthrography. We found that when epiphyseal protrusion was shown by the arthrograms it could be seen on the plain radiographs as well in all patients. Also, an acetabulum-head index of less than 90 or an acetabulum-head quotient of less than 92 as determined on plain radiographs correlated well with a diagnosis of protrusion. Thus, an arthrogram is not necessary to make the diagnosis of protrusion in most patients. The arthrogram is more useful in delineating changes in the articular surface for prognoses concerning arthritis and in tailoring the treatment to the individual patient.
我们评估了21例患有活动期Legg-Calvé-Perthes病儿童的X线平片和关节造影，以确定关节造影的价值。我们发现，当关节造影显示骨骺突出时，在所有患者的X线平片上也能看到。此外，X线平片上测得的髋臼-股骨头指数小于90或髋臼-股骨头商小于92与突出的诊断密切相关。因此，在大多数患者中，诊断突出并不需要关节造影。关节造影在描绘关节表面变化以预测关节炎以及为个体患者制定个性化治疗方案方面更有用。
