Developmental Dysplasia of the Hip

Developmental dysplasia (dislocation) of the hip (DDH) occurs when a child’s hip joint has not formed properly. The seriousness of the condition can range from the hip being slightly displaced to being dislocated easily. Approximately 1 in 1,000 children are born with a dislocated hip and 10 in 1,000 may have hip subluxation (partial dislocation).
