Who is affected by developmental dysplasia of the hip

About 1 in 100 newborns may have some form of developmental dysplasia of the hip (DDH). But a complete hip dislocation occurs in about 1 to 2 in 1,000 newborns.¹

If only one hip is affected, it is about 3 times more likely to be the left hip.²
DDH occurs about 5 times more often in girls than boys.²
