The problem: late diagnosis is a growing crisis
Hip dysplasia (DDH) is the most common musculoskeletal condition in newborns, affecting approximately 1 in 100 babies. Yet despite being highly treatable when caught early, late diagnosis is on the rise.
In New South Wales alone, cases of late-diagnosed DDH have increased tenfold over the past two decades. Babies born to first-time mothers, those with a family history of hip dysplasia, & children born in rural areas face a significantly higher risk & often miss the critical early screening window.
When diagnosis is delayed beyond the first few weeks of life, treatment becomes exponentially more complex, costly, & invasive. Early detection through newborn screening & clinical assessment is the key to preventing lifelong complications.
Why timing is everything
Early diagnosis (~95% success with Pavlik harness): When caught in the first weeks of life, hip dysplasia can be treated non-invasively with a Pavlik harness. Success rates exceed 95%, and treatment typically lasts 12-16 weeks with minimal long-term impact on your child's development.
Late diagnosis (7× costlier, surgery required): When diagnosis is delayed beyond 6 months, treatment becomes significantly more complex & expensive. Surgery is often necessary, recovery is longer, and the risk of complications increases substantially. Treatment costs can be 7 times higher than early intervention, & long-term outcomes are less predictable.
The window for non-invasive treatment is narrow. Every week counts. Early screening & prompt diagnosis are the keys to the best outcomes for your child.
Signs to look for
Watch for these early warning signs of hip dysplasia:
Uneven skin folds: Asymmetrical creases or folds on the inner thighs or buttocks may indicate hip dysplasia.
Limited leg movement: Reduced range of motion in the hip joint, especially when spreading the legs apart.
Leg length difference: One leg appears shorter than the other, or the knee sits at a different height when lying down.
Limping or waddling: An unusual gait or walking pattern that develops as the child becomes mobile.
Late walking: Delayed motor milestones or reluctance to bear weight on one leg.
Clicking or clunking: Audible sounds from the hip joint during movement or diaper changes.
What you can do
Take action to support hip dysplasia awareness:
Know the signs: Familiarise yourself with the early warning signs of hip dysplasia so you can spot them quickly in your own children or those around you.
Share the word: Talk to other parents, carers, & healthcare providers about the importance of early screening & awareness.
Support research: Advocate for better screening protocols & support organisations working to improve DDH outcomes and prevention strategies.
Contact your MP: Encourage your elected representatives to prioritise hip dysplasia screening in newborn health programs & public health initiatives.
