Developmental Dysplasia of the Hip

A condition present in early life in which the hip joint is poorly formed, so the ball can slip out of a shallow socket.

Key points

Developmental dysplasia of the hip is a poorly formed hip in which the socket is shallow and the ball can slip partly or fully out.
It is more common in girls, in breech babies, and where there is a family history, and newborns are screened for it.
In the newborn, the Ortolani and Barlow manoeuvres feel whether the hip can be slipped out of and back into the socket.
Later signs include uneven skin creases, a shortened leg, and limited spreading (abduction) of the hip.
If it is not found early, the child develops a limp or a waddling walk and the hip wears out early, so early detection matters greatly.

Memory trick

DDH is a shallow hip socket letting the ball slip out (girls, breech, family history); newborn Ortolani and Barlow tests; later uneven creases, short leg, limited abduction; missed cases limp and wear out early.
