Prevalence of Hip Ultrasound Abnormalities in Newborns With a Hip Click.

A hip click on examination of the newborn hip is believed to be the result of a ligament or myofascial structure and thought to be benign. Some studies suggest a link between hip clicks and developmental dysplasia of the hip. The purpose of our study is to estimate the prevalence of ultrasound hip abnormalities in newborns with a hip click and an otherwise normal physical examination.
