Real-time ultrasonographic examination in congenital dislocation of the hip

We have been using real-time ultrasonographic examination at Srinagarind Hospital since 1988, chiefly for confirming the diagnosis of subluxated and dislocated hips. We have also studied the click sensation, which is usually detected during Barlow and Ortolani tests in normal neonates. This article presents the significance, possible causes, and any correlation of the click sensation with congenital dislocation of the hip resulting from our study using real-time ultrasonography. No demonstrable subluxation or dislocation was found while the click sensation was created during the study.
