Congenital Hip Dislocation: A Parent’s Guide
Why doesn’t my baby open his legs wide when I change him?
Congenital hip dislocation (DDC) is like a puzzle where the piece of the femur doesn’t fit neatly into place.
It affects 1 in 1,000 newborns and, if not corrected in time, can cause lameness or arthritis in childhood.
What exactly is it?
Imagine the hip as a ball (head of the femur) spinning inside a bowl (acetabulum).
In the DDC:
- The ball is out of the bowl (total dislocation).
- Or the bowl is very flat and the ball comes out easily (dysplasia).
Key fact: 80% of cases are resolved with early detection.
Signs you shouldn’t ignore
- Shorter leg: One side looks “shrunk.”
- Uneven folds: The thighs have asymmetrical wrinkles.
- “Clicking” sound when moving the hip during bathing.
- Difficulty opening the legs when putting on the diaper.
Is it more common in girls? Yes, they have 5 times more risk.
Why does it happen?
Doctors are still investigating the causes, but these factors increase the risk:
- Genetics: Yes, there were cases in the family.
- Little space in the uterus: Twins or breech babies.
- Very flexible ligaments: By maternal hormones.
Tests to diagnose it
- Physical exam: The pediatrician moves the baby’s legs in an “M” shape (Ortolani maneuver).
- Ultrasound: For babies under 6 months. It shows how the hip is shaped.
- Radiography: In children older than 6 months, when the bones are most visible.
Treatments according to age
Pavlik harness (newborns to 6 months)
- It’s like a safety harness for the hip.
- Keep your legs in a frog position so that the ball returns to the bowl.
- It is used 23 hours a day for 6-12 weeks.
Casting or surgery (older babies)
- If the harness does not work, a special cast (spica cast) is placed.
- In severe cases, surgery is performed to reposition the hip.

No. Babies adapt quickly to the harness and can move normally.
2. ¿Puede prevenirse?
Avoid swaddling the baby with his legs straight (it is better to use a “wide diaper bag”).
3. ¿Deja secuelas?
With prompt treatment, 95% of children develop a normal hip.
4. ¿Es hereditario?
Yes. If you have a child with DDH, check on future babies from birth.
5. ¿Puede confundirse con otro problema?
Yes. An occasional snap doesn’t always indicate DDH, but it requires evaluation.
Prediction: What to expect?
Congenital hip dislocation has a solution.
The key is to act before the baby starts walking.
With medical follow-up, your child will be able to run, jump and play without limitations.
