摘要发育性髋关节发育不良（Development dysplasia of the hip，DDH）是小儿骨科常见的畸形之一，发病率高，早期诊断和治疗对患儿非常重要。长时间以来，DDH的诊断主要是依赖骨盆X线平片检查，DDH的病理变化特别复杂，除骨性结构的变化之外，软骨、盂唇及韧带的变化也愈来愈受到人们的重视，而且髋关节是一个需要进行三维评估的复杂结构，因此，X线平片提供的信息就显得非常有限。近几年，超声、CT、MRI等技术的发展非常迅速，自从MRI技术应用于临床以来，在DDH的研究、诊断及治疗方面展现出了巨大优势。
Abstract：Developmental dislocation of the hip(DDH) is one of the most common deformities in children, the incidence is high, early diagnosis and treatment of great significance. For a long time, the diagnosis and treatment of DDH mainly depended on the pelvic X-ray film examination, and the pathological changes of DDH were complicated. In addition to the changes of bony structure, the changes of cartilage, soft tissue and ligament are more and more valued. Hip joint is a complex structure that needs to be evaluated in three dimension. Therefore, the traditional X-ray film provides the clinical information appears to be very limited. In recent years, ultrasound, CT, MRI and other imaging technology development is very rapid. Since the application of MRI, it has shown great advantages in the research, diagnosis and treatment of DDH.
