Developmental Dysplasia of the Hip - D.D.H.

What is it?

Previously known as Congenital Dislocation of the Hip, this is a condition in babies and young children where one, or both of the hips is found to be out of joint – not properly located in its socket.

As with many other medical conditions, there is considerable variation in the severity.

The hip may be dislocated at rest, unstable at rest with a risk of subsequent dislocation, or alternatively the hip socket may be shallow and the cover for the head of the femur not good enough to provide long-term comfortable function in to the future – this is known as dysplasia.

How common is it?

The condition significantly affects around 1 or 2 in 1000 babies at birth, and between 5 and 20 may have some lesser form of instability, mostly requiring little or no treatment.

It is more common in girls than boys (about 6 to 1), more likely in a first born child, more likely after a breech birth, and a family history of the condition seems to statistically increase the risk. The left hip is more often affected than the right.

Treatments for D.D.H.

The choice of treatment is determined by a number of factors, especially the severity of the condition, and the age of the patient.
