Signs and tests:

Pediatricians routinely screen all newborns and infants for hip dysplasia. There are several methods to detect a dislocated hip or a hip that is able to be dislocated.

A hip that is truly dislocated in an infant should be seen, but some cases are mild and some develop after birth, which is why multiple examinations are recommended. Some mild cases are silent and cannot be found during a physical exam.

Ultrasound of the hip is the most important method to show hip deformity. A hip x-ray (joint x-ray) may be helpful in older infants and children.
