Developmental dysplasia of the hip, or DDH, is a term that refers to instability of newborn hips. This occurs when the hip joint does not develop normally.

This condition often appears during infancy, but may develop later in childhood. If the child’s symptoms are mild, it can go unnoticed during infancy and childhood. If left untreated, it might resolve on its own, or in some cases worsen, causing hip pain later in life. When this occurs, we refer to the condition as adolescent hip dysplasia.
