Hip Dysplasia in Babies
Hip dysplasia is a developmental disorder of the hip joints where the socket is too shallow and cannot properly hold the femoral head. It affects about 2-4% of all newborns and is screened via ultrasound at the U3 check-up. Detected early, it is very treatable — wide swaddling is often sufficient.
Possíveis Causas
- 1Genetic predisposition — runs in families
- 2Breech position during pregnancy — most common risk factor
- 3Firstborns and girls are more commonly affected (hormone relaxin)
- 4Low amniotic fluid (oligohydramnios) — restricted movement in the womb
- 5Too-tight swaddling or wrapping with legs straight (traditional wrapping techniques)
O Que Você Pode Fazer
- Wide swaddling: wide nappy or insert that keeps legs in abduction position
- Abduction brace (Tübingen hip flexion splint) — prescribed for mild to moderate dysplasia
- Pavlik harness: soft harness that holds hip joints in optimal position (6-12 weeks)
- Baby carrier/sling in spread-squat position — promotes hip development
- In severe dysplasia: plaster cast or surgical reduction under anaesthesia (rarely needed)
Quando Ir ao Médico?
- Clearly asymmetric skin folds on thighs and buttocks
- One leg appears shorter than the other
- Limited hip abduction (one leg cannot be spread as wide)
- Clicking or clunking sound during leg movement
- Limping or waddling gait when learning to walk
Notas por Faixa Etária
Hip screening via ultrasound is part of the U3 check-up (4th-6th week of life) and detects 99% of cases. The earlier treatment begins, the better the outcome. In the first 6 weeks, wide swaddling is often enough. Up to 3 months, the abduction brace is very successful. After 6 months, treatment becomes significantly more involved. Untreated hip dysplasia can lead to early arthritis and walking disability.
