OBJECTIVES: To assess the effectiveness of general ultrasound screening to prevent first operative procedures of the hip. STUDY DESIGN: We conducted a case-control study in a population in which general ultrasound screening supplementing clinical screening is recommended and offered free of charge for all children. Participation in ultrasound screening before week 7 as recommended in Germany was the exposure of interest. Case ascertainment was based on active surveillance in orthopedic hospitals. The case definition was: first operative procedure for developmental dysplasia of the hip (closed reduction, open reduction, or osteotomy) in children >9 weeks old and <5 years old and born between 1996 and 2001. Control subjects from the same birth cohorts were recruited in telephone surveys. RESULTS: Cases of first operative procedures for developmental dysplasia of the hip (n = 446) were compared with 1173 control subjects for ultrasound screening. Effectiveness of ultrasound screening to prevent first operative procedures for developmental dysplasia of the hip was estimated as 52% (95% CI, 32-67). Effectiveness did not vary substantially for closed and open reductions and osteotomy. CONCLUSIONS: General ultrasound screening reduces the rate of operative procedures for developmental dysplasia of the hip; the impact on developmental dysplasia of the hip. Treatment rates and avascular necrosis need further assessment to balance the benefit against potential overtreatment and adverse effects.
