Abstract
This study is to determine the normal values of the alpha and beta angles
in normal newborns and to describe the changes of the angles during stress
maneuver by ultrasound.
Coronal examinations of the hip at rest and stress were performed using a
high frequency linear ultrasound probe (5-7.5 MHz) on 49 newborns at
Hospital Universiti Sains Malaysia from January 2003 till March 2004.
The means of the alpha angles of the right and left hips without stress were
62.0 degrees (SD ± 6.4 degrees), 62.0 degrees (SD ± 5.6 degrees)
respectively and with stress were 63.3 degrees (SD ± 7.2 degrees), 59.8
degrees (SD ± 8.0 degrees). The means of the beta angles of the right and
left hips without stress were 56.8 degrees (SD ± 7.4 degrees), 56.2 degrees
(SD ± 7.0 degrees) respectively and with stress were 54.9 degrees (SD ±
7.1 degrees), 58.2 degrees (SD ± 8.7 degrees). The normal alpha and beta
angles of the hip joints were comparable with the Caucasians. There was
significant difference in the alpha and beta angle without and with stress.
