发育性髋关节发育不良(development dislocation of the hip,DDH)是婴儿常见的发育性骨关节畸形之一。未经治愈的DDH有随着患儿生长发育而病情逐渐加重甚至恶化,DDH是成年人退化性髋关节炎病变的主要原因。因此,早期诊断DDH能改善治疗效果,降低出现并发症的风险。近年来DDH的早期筛查在国内外受到重视,高频超声检查对婴儿髋关节结构具有高分辨力、重复性好且无放射性损害的特点,已成为早期诊断DDH的首选方法。本文就高频超声检查在婴儿DDH中的应用现状及进展予以综述。
Developmental dislocation of the hip (DDH) is one of the common developmental osteoarthropathy in infants. Unhealed DDH with the growth and development of children and the disease gradually aggravated or even worse, DDH is the main cause of adult degenerative hip arthritis. Therefore, early diagnosis of DDH can improve the therapeutic effect and reduce the risk of complications. In recent years, early screening of DDH has been paid much attention at home and abroad. The high-frequency ultrasound has the characteristics of high resolution, good repeatability and no radioactive damage in the hip joint of infants. It has become the first choice for early diagnosis of DDH. This review summarizes the application and progress of high frequency ultrasound in infant DDH.
