【Abstract】 AIM: To investigate the value of ultrasonic examination for earlier diagnosis of developmental dislocation of the hip (DDH) by measuring the ultrasonography of infant hip α angle, β angle and acetabular coverage of femoral head (MR value). METHODS: - MHz linear transducer ethod. In 17 cases suspected as developmental dysplasia of hip, 19 hips underination, and normal control group onth age. RESULTS: Ultrasonic examination basically demonstrated the anatomic structure of frontal profile of infant hip. In normal control group, α angle al group, MR and α angle reflecting the development of osseous acetabulum decreased, and β angle reflecting the development of cartilaginous acetabulum increased. Ultrasound also displayed glenoid labrum and other soft tissues of acetabulum ethod for earlier diagnosis and folloination of infant DDH.
【Keyental dysplasia of hip,DDH)是婴幼儿骨骼系统最常见的疾病之一,约1%~10%的新生儿出生时有髋关节发育不良、脱位及半脱位倾向. 在我国各地发病率也不同,南方较低,北方较高,‰~‰[1]. 临床上常用的体格检查和X线检查的可靠性和安全性仍然存在很大争议,高分辨的超声波可以较好地穿透尚未完全骨化的髋关节,并能够动态观察,辅以X线为DDH的诊断提供依据.
1对象和方法
(男4,女13)例,年龄1~12(±) mo,根据异常组婴儿的月龄设立正常对照组婴儿17(男4,女13)例.
,背对检查者,髋关节屈曲,探头置于大转子上,纵轴与躯干纵轴平行,前后平移探头,获得较清晰的髋关节冠状断面声像图. 然后将婴儿反方向侧卧,以同样的方法将扫查左侧髋关节. 根据Graf的三点系统[2],观察股骨头、髋臼的结构和空间位置及髋臼盂缘. 以水平的髂骨作一直线,即基线(A);以骨性髋
