Infant Hip Ultrasound
Safe screening for the early diagnosis of developmental hip dysplasia (hip dislocation).
What is hip dislocation?
Hip dislocation in babies (Developmental Hip Dysplasia) is the condition in which the head of the thigh bone does not fully sit in its socket in the hip or slips out of the socket. This problem arises from a shallow hip socket or laxity of the ligaments holding the joint.
What is hip dislocation (developmental hip dysplasia) screening?
Hip dislocation screening is a test performed to diagnose hip dislocation early in babies. The screening is usually done with a physical examination and a hip ultrasound. Ultrasound provides detailed imaging of the hip joint and shows whether there is any dislocation or developmental problem.
Why is hip dislocation (developmental hip dysplasia) screening important?
Hip dislocation is a treatable condition when diagnosed early. If not treated during infancy, it can lead to walking difficulties, pain and permanent joint damage in later years. With early diagnosis, treatment may be possible with simple interventions without the need for surgery. Permanent disabilities can be prevented with early diagnosis and appropriate treatment.
What are the signs and symptoms of developmental hip dysplasia?
The signs and symptoms of developmental hip dysplasia may vary according to the severity of the condition. The condition may go unnoticed by the family until the baby starts to walk, and treatment may be delayed. Therefore it is very important to screen every baby for hip dislocation at the appropriate time. Signs and symptoms such as delay in sitting, crawling or walking, limping, a difference in length between the two legs, muscle problems due to less use of the affected side, pain and limited movement may be seen.
Who is developmental hip dysplasia screening performed on?
Every newborn baby should be screened for developmental hip dysplasia (hip dislocation).
When should hip dislocation (developmental hip dysplasia) screening be done?
For the ultrasound examination, it is performed, if possible, at 6–8 weeks.
Should hip dislocation screening be done even if there are no findings?
Yes, hip dislocation screening should be done even if there are no findings. Signs of hip dislocation in babies are not always easy to notice.
Is there radiation in this examination?
