title: Ultrasonography in the early diagnosis of congenital dysplasia of the hip.
abstract: The authors discuss the feasibility of using ultrasonography in the early diagnosis of congenital dysplasia of the hip. Having used the methods of Graf and Harcke, they devised a new scan which always reveals the state of the limbus in neonatal congenital dysplasia. This has been used for two years as an additional technique in neonates with a positive Ortolani click to demonstrate the presence of an inverted limbus, which is not revealed in the Graf and Harcke scans although they give a very good overall picture of the femoral head and acetabulum. The disclosure of an inverted limbus at this early stage is of crucial importance in determining the correct treatment to be adopted.
