title: [Clinicaly silent developmental hip dysplasia--significancy of the hip ultrasonographic examination].
abstract: We present the significancy of the hip USG examination in the diagnosis of the clinically silent developmental hip dysplasia (DDH). The clinical and ultrasonographic hip assessment were performed in 972 children and sonographic abnormalities silent in clinical examination were stated in 155 of them (15.9%). Physiological immaturity was stated in 87% of this group. An orthopedic treatment was nessesery in 34 children (3.5% of cohort). Children with pathological hip dysplasia (type II D or above according to the Graf classification) with no pathological signs in clinical assessment constituted 0.25% of the cohort. We claim the USG examination of the infant hip is a method of choice in the early diagnosis of the DDH and the only method to detect clinically silent DDH.
