The advancement in the early diagnostics of developmental hip dysplasia in infants--the role of ultrasound screening.

Developmental hip dysplasia (DDH) is a deformation of the locomotor system that can occur on previously normal bone structures in late fetal development. The study was undertaken to determine the value of continuous ultrasound screening in early diagnosis of DDH. In the area covered by the Labin Primary Health Center, clinical and ultrasound examination of the hips was performed in all children during the fourth month of life from 1989 to 2001.
