What it is
It is more common in girls, first-born babies, babies who were breech, and when there is a family history.
A harness (Pavlik harness) worn for several weeks usually corrects it. If it is found later, a cast or surgery may be needed. Untreated DDH can lead to a limp and early arthritis.
Common signs
- Often no visible signs; found at newborn checks
- Legs of different lengths
- Uneven skin folds on the thighs
- Less movement or flexibility on one side
- A limp once walking
How it is usually diagnosed
- Newborn and 6 to 8 week physical examination
- Hip ultrasound in young babies
- X-ray in older babies
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Hip check results
- Ultrasound and X-ray reports
- Harness treatment dates
- Orthopaedic letters
Questions to ask your doctor
- How long will my baby need the harness?
- How do we care for the baby in the harness?
- What follow-up checks are needed?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- There are no emergency signs specific to DDH; a child who suddenly cannot bear weight or has a painful hip with fever needs urgent care
