At my daughters 4 month check up her doctor noticed that her hips were asymmetrical… So the next day we were at the Childrens Hospital getting an ultrasound for Developmental Dysplasia of the HIP (DHH). Luckily everything turned out OK but I decided to do a little research.
The cause of this is not really known – some say hereditary and others may say breech birth or C-section. In my case my daughters hips were asymmetrical and one leg was slightly longer than the other, he wasn’t too concern but as a precaution he just wanted to get the testing done.
