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. If your doctor suspects hip dysplasia, he or she might also suggest imaging tests, such as X-rays or ultrasound.
At Mayo Clinic, tests are scheduled quickly and results are usually available on the same day or within 24 hours. Efficient testing helps Mayo specialists quickly arrive at a diagnosis so your treatment can begin as soon as possible.
Signs and symptoms vary by age group. 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.
If hip dysplasia is not corrected during infancy, the problem can worsen and may lead to early osteoarthritis.
Hip dysplasia tends to run in families and is more common in girls. The risk of hip dysplasia is also higher in babies born in the breech position.
