📖What is Hip Dysplasia in Babies (DDH)?

Hip dysplasia (DDH) is when a baby's hip joint doesn't form properly. Learn about screening, early detection with ultrasound, treatment from Pavlik harness to surgery, and what to expect for your child's development.

đŸ”ŦWhat Causes It?

  • Hip joint doesn't develop normally before or after birth
  • Hip socket (acetabulum) is too shallow to hold the ball (femoral head)
  • Ligaments around the hip are too loose, allowing instability
  • Abnormal positioning in the womb (breech position)
  • Genetic factors - runs in families
  • Hormones during pregnancy that loosen mother's ligaments may affect baby

⚠ī¸Risk Factors

ℹī¸

You may be at higher risk if:

  • First-born baby (less room in womb)
  • Breech position (bottom-first) in late pregnancy or at birth
  • Female gender (6-8 times more common in girls)
  • Family history of DDH
  • Oligohydramnios (low amniotic fluid during pregnancy)
  • Being part of a twin or multiple pregnancy
  • Other 'packaging problems' - torticollis, metatarsus adductus, clubfoot
  • Indigenous Australian heritage (slightly higher rates)
  • Large birth weight

🛡ī¸Prevention

  • ✓Attend all scheduled baby health checks where hips are examined
  • ✓Use hip-healthy swaddling - allow legs to bend up and out
  • ✓Avoid tight swaddling with legs straight down
  • ✓Use proper baby carriers that support hip position (legs spread, knees higher than bottom)
  • ✓Tell your doctor about any family history of DDH
  • ✓Ensure high-risk babies get ultrasound screening
  • ✓Early detection through screening programs - DDH is highly treatable when caught early
