The earliest accurate assessment of the pathologic anatomy in congenital hip dysplasia allows for the most effective treatment and ultimate joint development. Computerized tomography has been suggested to better delineate bony orientation, size, and congruity; however, the inability of the routine CT scan to clearly depict cartilaginous structures has further confirmed the adequacy of the arthrogram alone in most patients. We present a technique employing computerized tomography following routine arthrography to more thoroughly assess the cartilaginous and soft tissue structures in the younger patient. Although certainly not indicated in all patients, this technique provides an effective diagnostic adjunct in select patients with complicated hip dysplasia early in the hip development.
对先天性髋关节发育不良的病理解剖进行最早的准确评估，有助于实现最有效的治疗和最终的关节发育。有人提出计算机断层扫描能更好地描绘骨骼的方向、大小和一致性；然而，常规CT扫描无法清晰显示软骨结构，这进一步证实了在大多数患者中仅关节造影就足够了。我们介绍一种在常规关节造影后采用计算机断层扫描的技术，以更全面地评估年轻患者的软骨和软组织结构。虽然肯定不是所有患者都需要，但这项技术为髋关节发育早期患有复杂髋关节发育不良的特定患者提供了一种有效的诊断辅助手段。
