"Paediatric normal measurements on CT "
"The normal width differs for different ages and whether the measurement is with CT or x-ray. At age 20 years the width measures ~6 mm on x-ray and at age 50 years it measures ~3 mm. Women tend to have a thicker fibrocartilaginous disk that allows higher mobility of the pelvic bones and assists in childbirth. During pregnancy, due to the presence of certain hormones like relaxin, the gap in the symphysis pubis can increase by 2-3 mm."
