What is Developmental Dysplasia of the Hip (DDH)?

Developmental Dysplasia of the Hip (DDH) is a hip problem resulting from hips being forced into a stretched-out position too early and the thighbone doesn’t securely fit into the shaped socket. A baby is born with this or happens during the first year of life. It is not painful and may be undetected until the child is on the walking stage.

Who are susceptible in developing DDH?

Infants younger than 6 months have very fragile ligaments and that they are more susceptible to hip dysplasia. So doing the right thing at the very beginning and being aware of the correct positioning of infants will prevent DDH from happening.

What interferes with healthy hip positioning?

Baby carriers, swings, car seats, bouncers, walkers, jumpers, rockers and slings. These devices can interfere in developing a healthy hip as they may inadvertently place your child’s hip in unhealthy position. Also some swaddling techniques can contribute in developing DDH.

Here are some images from International Hip Dysplasia Institute that illustrate the correct positions of infant in a baby carrier, sling and car seat.
