Developmental Dysplasia of the Hip (DDH)

Also known as: Hip dysplasia, DDH.

What is Developmental Dysplasia of the Hip (DDH)?

DDH is a spectrum of conditions that range from a hip that is slightly shallow to a hip that is not in the hip socket. It occurs in 1 to 4% of newborn children.

What Causes DDH?

The biggest risk factor for DDH is breech (feet first) position of the fetus before birth. Other risk factors include a family history of hip dysplasia, decreased amniotic fluid, female gender and first-born children.

How is DDH diagnosed?

DDH is usually diagnosed soon after birth by the pediatrician. Children are referred to pediatric orthopedists for further evaluation. Nicklaus Children's Department of Orthopedics is among the region‘s most experienced in treating DDH. Early examination and treatment by a pediatric orthopedist is key to obtaining the optimal result.

What are DDH Care Options?

Options for care depend on the extent of the condition and the age of the child. Infants can often be treated with a special harness or brace, while older babies and toddlers may require a treatment with a special cast or surgery.
