If you’ve been reading about hip dysplasia, you’ve likely come across step-by-step descriptions of the Barlow and Ortolani tests, the maneuvers doctors use to check a newborn’s hips.
It’s a natural instinct to want to check yourself. But these are not simple screening tools you can safely replicate at a changing table.
They are deliberate provocation maneuvers, designed to push a hip out of its socket and then guide it back in, and even in trained hands they miss a meaningful share of cases.
Attempted at home, they carry a real risk of injuring a joint that is still mostly cartilage.
That doesn’t mean parents are powerless. There’s a real, useful distinction between performing a clinical test and simply noticing something during ordinary care.
Prior results do not guarantee a similar outcome.
Why the Barlow and Ortolani Tests Should Never Be Done at Home
A pooled analysis of 25 studies and more than 72,000 infants found that the combined Ortolani-Barlow exam catches only 36 percent of true DDH cases, with a specificity of 98 percent.
In plain terms, a negative result is usually trustworthy, but the test misses close to two-thirds of babies who actually have the condition. Repeating both maneuvers together improves sensitivity to roughly 57 percent, still missing nearly half of true cases.
Screening Method | Sensitivity | Specificity |
|---|---|---|
Ortolani-Barlow exam alone | 36% | 98% |
Ortolani-Barlow, repeated/combined | 57% | 95% |
Limited hip abduction test | 45% | 78% |
Hip ultrasound (Graf method) | 93% | 97% |
That gap is exactly why ultrasound, not repeated hands-on exams, is the tool guidelines lean on for high-risk babies. It’s also why a home attempt at these maneuvers is a bad trade.
The Barlow test flexes the hip and knee to 90 degrees and applies gentle backward pressure to see if the femoral head can be pushed out of the socket.
The Ortolani test does the reverse, guiding an already-dislocated hip back in while feeling for a distinct clunk, a sensation felt through the examiner’s fingertips, not a sound a parent could pick up by ear.
Applying that kind of deliberate dislocating force without training risks the exact cartilage and ligament damage the test is designed to detect.
What Causes Hip Dysplasia and Who’s at Higher Risk
Hip dysplasia affects an estimated 1 in 100 newborns in its clinically detectable form and roughly 1 in 1,000 in its fully dislocated form. It’s not caused by anything a parent does during pregnancy or after birth. It’s a structural developmental issue where the acetabulum, the hip socket, doesn’t fully cover the femoral head.
Risk isn’t distributed evenly. The original AAP clinical practice guideline, still the reference point cited in current pediatric literature, quantified newborn risk precisely:
Risk Profile | Newborn Risk per 1,000 |
|---|---|
Female infant, no other risk factors | 19 |
Breech presentation, female | 120 |
Breech presentation, male | 26 |
Family history of DDH, female | 44 |
Family history of DDH, male | 9.4 |
A girl born breech carries roughly a 12 percent risk, meaningfully higher than a boy with the same presentation.
One more pattern worth knowing the left hip is affected roughly three times more often than the right, attributed to the typical left-facing fetal position pressing against the left hip in the final weeks of pregnancy.
What Can Parents Safely Notice During Everyday Care
None of this requires forcing your baby’s legs into any position. These are things you might notice incidentally while diapering, bathing, or dressing your baby, worth mentioning at the next visit rather than acting on yourself.
Uneven skin folds on the back of the thighs or buttocks, though this sign alone has low specificity and is common in babies with normal hips too
One leg that appears shorter than the other when your baby lies on their back with legs gently straightened
A hip that doesn’t spread outward as easily as the other during a diaper change
A distinct clunk, not a high-pitched click, felt during normal movement
A high-pitched click on its own is a common, benign finding, usually from a tendon moving over bone, and isn’t the same as the deep clunk a clinician feels during a proper exam.
Because parents aren’t trained to reliably tell the two apart, and because skin-fold asymmetry alone means little in isolation, the useful move with any of these observations is a direct question at the pediatrician’s office, not a home diagnosis in either direction.
What Changes Once Your Child Starts Walking
In toddlers with dysplasia affecting one hip, a limp is usually the first noticeable sign. When both hips are involved, it often shows up as a waddling gait with an exaggerated lower back curve instead.
A child who avoids putting weight on one leg, sits down often during play, or tires faster than expected on short walks may be showing hip discomfort through behavior rather than words.
A visible leg length difference or a pelvis that tilts to one side as your child stands also warrants a prompt exam rather than a wait-and-see approach.
Could a Delayed Diagnosis Be a Sign Something Was Missed
Most late diagnoses happen despite genuinely appropriate care. What matters legally is whether the standard of care, described above, was actually followed given what was known about a specific baby.
When treatment starts before three months of age, a Pavlik harness resolves the issue in roughly 90 percent of cases, with a reported avascular necrosis complication rate of about 3 to 12 percent. A toddler diagnosed at 12 to 18 months, by contrast, often needs closed reduction under anesthesia and months in a cast, sometimes open surgery if that fails.
That gap in outcomes is why a delayed diagnosis is worth a closer look when:
A breech birth or family history was documented but no ultrasound was ever ordered or discussed
A reported concern about asymmetry, clicking, or limited motion isn’t reflected anywhere in the medical record
Well-baby visit notes show no documented hip exam at one or more checkups
An equivocal finding at two weeks was never followed up with a recheck or ultrasound by six weeks
A limp or gait abnormality was dismissed as something your child would grow out of without an exam
None of this automatically means malpractice occurred. It means the timeline is worth having reviewed against what the standard of care required.
What Are the Key Deadlines in a New York Hip Dysplasia Case
Situation | Deadline | Rule |
|---|---|---|
Child’s claim against a private hospital, doctor, or provider | The earlier of age 18 plus 2.5 years, or 10 years from the malpractice (in practice, almost always the 10-year cap for an infancy-era diagnosis) | |
Notice of claim if a public or municipal hospital was involved | 90 days; no automatic toll just because the child is a minor, though courts can permit late notice in limited circumstances | |
Parent’s own derivative claim | 2.5 years from the date of the malpractice, not extended by the child’s infancy |
Summing It Up
The numbers tell a consistent story. Hands-on exams catch roughly a third to a little over half of true cases even done well, ultrasound catches over 90 percent, and a diagnosis made before three months resolves in 9 out of 10 babies with nothing more than a harness.
The whole system depends on risk factors being flagged, equivocal findings being followed up, and imaging being ordered when it’s supposed to be.
Porter Law Group works with New York families whose children faced more invasive treatment than they should have because a step in that process was skipped. If that sounds like what happened to your child, we’re ready to review the medical records and explain what the standard of care required.

Frequently Asked Questions
Can I do the Barlow or Ortolani test on my own baby at home?
No. Even performed correctly by trained clinicians, the combined exam misses roughly two-thirds of true cases, so a normal result at home wouldn’t tell you much anyway, and the maneuver itself carries a real risk of injuring an infant hip if done without training.
My baby’s hips click sometimes. Is that dysplasia?
Usually not. A soft, occasional click from a tendon moving over bone is common in healthy infants. The finding doctors look for is a distinct clunk felt through the hands, not a sound. Persistent clicking combined with a risk factor like breech birth is worth mentioning to your pediatrician.
Does every baby need a hip ultrasound?
No. Ultrasound is reserved for babies with risk factors such as breech presentation, a family history of DDH, or an equivocal exam. A girl born breech carries roughly a 12 percent risk, which is why that combination in particular gets flagged for imaging even with a normal exam.
What if my toddler wasn’t diagnosed until after they started walking?
A later diagnosis usually means more involved treatment, closed or open reduction and casting rather than a harness alone. That alone doesn’t mean malpractice occurred. It’s worth having the medical record reviewed if risk factors or symptoms were reported and not acted on.
How much does a birth injury or malpractice lawyer cost in New York?
Porter Law Group works on a contingency fee basis. There’s no upfront cost, and no fee unless we recover compensation on your behalf.
