Description
Summary:To develop an electronic navigation system to increase reliability and comparability in the ultrasound screening of developmental dysplasia of the hip (DDH). The impact of the navigation system on transducer positioning and on sonographic measurements according to Graf was analyzed. Twenty hips in newborns were examined sonographically using a new navigation system capable of detecting the transducer and pelvis position in order to calculate the relative tilt in the frontal, axial, and sagittal-plane. In each newborn an ultrasound image was obtained conventionally according to Graf and a second image using the sonographic navigation system. Relative roll and pitch angles and sonographic measurements were analyzed using paired T-tests and Levene-tests. Relative tilt angles in the conventional group ranged from − 8.9° to 14.3° (frontal-plane) and − 23.8° to 14.2° (axial-plane). In the navigation-assisted group ranges from − 3.0° to 3.5° and − 2.8° to 4.5° were observed. Variances were significantly lower in the navigation-assisted group ( p
