Hello and welcome to the Zero to Finals podcast. My name is Tom and in this episode I'm going to be

talking to you about developmental dysplasia of the hip. And you can find written notes on this topic

at zero definals.com slash developmental dysplasia or in the orthopedic section of the

zero to finals pediatrics book. So let's get straight into it.

Developmental dysplasia of the hip, or DDH, is a condition where there are structural abnormalities

in the hips caused by abnormal development of the fetal bones during pregnancy.

This leads to instability in the hips and a tendency or potential for subluxation or dislocation

of the joint.

These structural abnormalities have the potential to persist into adulthood, which leads to

weakness, recurrent subluxation or dislocation, abnormal gait, and

early degenerative changes causing arthritis. Developmental dysplasia of the hip is either picked up

during the newborn examinations or later when the child presents with hip asymmetry, reduce

range of motion in the hip or a limp.

So what are the risk factors?

Well, the key things to look out for

which may put a child at risk of developmental dysplasia

are a first-degree family history,

breach presentation from 36 weeks onwards during the pregnancy,

a breach presentation at birth if they're born after 28 weeks gestation,

and a multiple pregnancy, for example twins or triplets.

Let's talk about screening.
