Ultrasonographic Examination of Newborns for CDH

We examined 68 newborns (136 hips) by ultrasonography using Graf's method from November 1996 to May 1997. Eighty one hips were type I a, 41 hips were type I b, 13 hips were type II a+, and one hip was type II c. Dysplastic hips were reexamined after one month. Dysplastic hips had improved to type I a or type I b.
