Developmental dysplasia of the hip (DDH) is a condition in which a baby's hip joint has not formed properly, so the ball of the thigh bone is loose in, or out of, its socket. Babies' hips are checked at newborn and early infant examinations, because early treatment usually works very well.
Key takeaways
- Risk is higher in girls, first-born babies, babies who were breech and when there is a family history.
- An ultrasound is used if the hip feels unstable or the baby has risk factors.
- Early treatment is usually a soft harness worn for several weeks.
What you can do
- When swaddling, leave room for the legs to bend up and out at the hips.
- Use carriers that support the thighs in a wide "M" position.
When to talk to your doctor
See your doctor if one leg looks shorter than the other, the skin creases on the thighs look uneven, one leg moves less, or your child limps when they start walking.
Frequently asked questions
Usually not; it is often found only through examination, which is why routine checks matter.
