How is Perthes disease diagnosed?

If your child is experiencing symptoms of Perthes disease, your healthcare provider will order an X-ray. X-rays are a common way to confirm a diagnosis. Your provider may also order additional studies, such as an MRI, to see how far the disease may have progressed.

Your healthcare provider may also use other tests to check the disease's progress. These include measuring your child’s thigh to determine if there is muscle atrophy (loss of muscle tissue). Your provider may also have your child perform some activities to test their range of motion.
