AIM OF STUDY: To assess the effectiveness of a universal sonographic screening of developmental dysplasia of the hip (DDH) established in Germany since 1996. METHODS: Currently a national survey is being performed in Germany to identify infants and young children who receive inpatient treatment for DDH. Between May, 1997 and October, 1997 monthly questionnaires were sent to all pediatric orthopaedic surgeons (active surveillance) and they were asked to report all inpatient cases between 10 weeks of age and 5 years with current closed or open reduction and/or osteotomies due to DDH. Information on time and results of previous ultrasound screening as well as treatment modalities was obtained in reported cases. RESULTS: 129 children (mean age at hospital admission 15.9 months, range 1.1 to 57.1 months) underwent closed reduction (n = 51), open reduction (n = 40) and osteotomies of the hip (n = 38) in the 6-month study period. Ultrasound screening has been performed too late and not at all in 45 children (35.1%). While in 18 cases (13.7%) no information could be obtained on screening results, the majority of children (n = 66, 51.2%) had completed DDH screening prior to the sixth week of life as recommended. Preliminary calculation of the unadjusted incidence of inpatient treatment for DDH in Germany was 0.33 per 1000 livebirths. CONCLUSION: DDH cases are still identified after introduction of an universal ultrasound hip screening in Germany. Continued evaluation must show, whether the incidence will decrease throughout the next few years.
