The aim of the present study was to assess the efficiency of ultrasonography in the screening of hip joints in newborn babies. In 1987, 2,531 newborns (92.4% of all liveborn babies) were examined clinically and with ultrasound. The coverage of the femoral head by the bony acetabular roof was measured on a longitudinal, coronal scan. The mean head coverage was 57% in boys and 55% in girls (p = 0.0001). Unstable hips, shown by both ultrasound and clinical examination, were found in 27 newborns (1.1%). The mean head coverage of unstable hips was 41%, significantly lower than for stable hips. No late hip dislocations were diagnosed in children with normal findings who were not included in the follow-up routines. In conclusion, the study indicated that ultrasonography measuring the femoral head coverage is an appropriate method of screening in newborns. It is useful for differentiating between a true and a false positive Ortolani sign. Moreover, ultrasound can show hip dysplasia that is not clinically demonstrable at birth.

D006618	Hip Dislocation, Congenital	Congenital dislocation of the hip generally includes subluxation of the femoral head, acetabular dysplasia, and complete dislocation of the femoral head from the true acetabulum. This condition occurs in approximately 1 in 1000 live births and is more common in females than in males.
