Description[edit | edit source] The instability of the hip may be assessed by the Ortolani and Barlow tests, which play a big role in the clinical screening for developmental dysplasia of the hip [1]. Each hip should be examined separately [2]. An infant with a positive examination result, defined as either a positive Ortolani or Barlow sign, should be referred to an orthopedist [3].

It is named after Dr. Thomas Geoffrey Barlow, who devised this test[7]. The Barlow test is a provocative maneuver used to reveal hip instability. The test is performed by:
The sensitivity of the Barlow maneuver with experienced hands (ranging from 87 to 97 percent) and specificity varies from 98 to 99 %. Ortolani Test[edit | edit source]The Ortolani Test was first described in 1936 by an Italian pediatrician Marino Ortolani [10]. The test is performed bu Placing the baby in a supine position with flexed hips at 90 degrees.

Hip Dysplasia Presentations in the Infant 2 Months or Older[edit | edit source]After 2-3 months of age, the Ortolani test and Barlow maneuvers are less sensitive but several other physical exam findings become more apparent:

What are signs of hip dysplasia in babies?In infants, you might notice that one leg is longer than the other. Once a child begins walking, a limp may develop. During diaper changes, one hip may be less flexible than the other. In teenagers and young adults, hip dysplasia can cause painful complications such as osteoarthritis or a hip labral tear.
How do you assess hip dysplasia in infants?During well-baby visits, doctors typically check for hip dysplasia by moving an infant's legs into a variety of positions that help indicate whether the hip joint fits together well. Mild cases of hip dysplasia can be difficult to diagnose and might not start causing problems until you're a young adult.
How do you assess for developmental dysplasia of the hip?Serial physical examination remains the primary method for diagnosing developmental dysplasia of the hip in infants. In many U.S. institutions, ultrasound examination is used to evaluate newborns and young infants who have an abnormal hip on physical examination.
Which clinical finding suggests developmental dysplasia of the hip in an infant?Early clinical manifestations of developmental dysplasia of the hip (DDH) are identified during examination of the newborn. The classic examination finding is revealed with the Ortolani maneuver, in which a palpable "clunk" is present when the hip is directed in and out of the acetabulum and over the neolimbus.
