Aims: The purpose of this study is the evaluation of the ultrasound screening process for DDH in a population of neonates from the prefecture of Chania, in Western Crete, an area with a history of excessively high incidence of DDH. Methods: Within the period between 1/7/99 and 1/7/01 (24 months) 1247 neonates (2494 hips) were examined clinically and ultrasonograþcally (transverse, oblique, dynamique views), all babies whose parents both descend from this area for generations. They were referred by a paediatrician for one or more of the following reasons: limited hip abduction (48%), hip laxity (6%), positive family DDH history (27%), musculoskeletal congenital abnormalities (11%), breech delivery (5.1%), paediatricianñs or parentsñ insecurity (18%).Results: We had the following þndings: signiþcant dysplasia-Graf III in 3.7%, milder dysplasia Ð Graf IIc, d in 7.2%, immature but satisfactory hips Ð Graf IIa, b in 19.3% and normal hips in 69.5% of the hips. Double diapers (sheets) were used in 43%, Frejka in 3% and Pavlik harness in 4.2% of the cases. In two cases the dysplasia persisted and we had to use a spica cast. Satisfactory results have been observed in all but one case. X-ray control was necessary in six children. Conclusion: Hip ultrasound, in experienced hands, is a safe, quick, well tolerated, non-inventory method for DDH screening, treatment and follow-up in neonates Ð babies in their þrst year of life.
