Developmental Dysplasia of the Hip (DDH)
DDH describes a variety of conditions in which the ball and socket of the hip do not develop properly. These include hips where the hip joint is dislocated (out of joint), unstable (hip is in joint but can come out of joint) and hips where the hip joint is stable but abnormally shaped.
The hip joint is similar to a ball in a socket. DDH means the ball of the hip either comes out of the socket or the socket has not developed properly. This condition used to be known as congenital dislocation of the hip (CDH).
