   【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: 5.0-7.5 MHz linear transducer was used for the frontal ultrasonographic sectional study of infant hip according to Grafs method. In 17 cases suspected as developmental dysplasia of hip, 19 hips underwent ultrasonic examination, and normal control group was set up according to month age. RESULTS: Ultrasonic examination basically demonstrated the anatomic structure of frontal profile of infant hip. In normal control group, α angle was 65.3°±4.5°, β angle 40.6°±7.5°, MR value (64.2±5.2)%; in DDH group, α angle 48.4°±6.2°, β angle 53.0°±10.1°, MR value (40.6±10.8)%. Compared with normal 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 which couldnt be displayed by Xray. CONCLUSION: Ultrasonagraphy of the infant hip is a convenient, fast, noninvasive method for earlier diagnosis and followup examination of infant DDH.
