Developmental Dysplasia of the Hip

Our doctors are known nationally for their skill in treating developmental dysplasia of the hip. We have an experienced ultrasound unit that produces high-quality images to help your child’s doctor choose the right treatment.

We have years of experience making custom braces and splints to help correct hip problems. Read about braces and splints and our other orthotics and prosthetics services.

• The compassionate experts you need are here

  To restore or improve your child’s health, function and quality of life, we often use nonsurgical methods (like physical therapy and braces), recommending surgery only when we believe it will give your child the best results. Many of our pediatric orthopedic surgeons have expanded fellowship training.

  We have the largest group of board-certified pediatric radiologists in the Northwest. Our radiologists have special expertise using ultrasound to look for bone and joint changes so we can work with your child to help prevent future problems. If your child needs imaging that uses radiation, we use the lowest amount possible to produce the best image. We also have a 3D low-dose radiation X-ray machine, called the EOS, for safer full-body 3D images.

• Treating the whole child

  We see your child as a whole person. Infants, children and teens are still developing, so they may need different care than adults do, like treatment that takes their growth plates into account. Here, your child’s team has special training in the medical, surgical, emotional and social needs of young people.

It is important to find developmental dysplasia of the hip early to treat it successfully. In the first few months of life, babies often can wear a type of harness to fix the problem. But babies older than 6 months often need surgery, and those who are older than 1 year almost always need surgery.

Treatment depends on how old your child is when DDH is found. All types of treatment have 1 goal: putting the hip joint back in place and keeping it there. This kind of treatment is called reduction, and there are several methods.

• Treatment from 0 to 6 months of age

  The youngest babies may wear a Pavlik harness. This is a soft harness that flexes and pulls the baby’s legs away from their middle while allowing the baby to move their legs. The harness keeps the ball (femoral head) at the top of the thighbone positioned deeply in the socket.

  This is the simplest form of reduction treatment and works 90% of the time. It allows the baby to exercise their legs while redirecting the thighbone into the hip socket.

• Treatment from 6 to 18 months of age

  If the Pavlik harness is unsuccessful or if a child is older than 6 months, they may need a body cast or a brace to hold the thighbone in the hip socket.

  Doctors either manipulate your child’s joint with a cast or harness (closed reduction) or operate to put the thighbone in the socket (open reduction).

  Open reduction is necessary for about 10% to 20% of children with DDH who are 6 to 18 months of age. During the procedure, the doctor opens the hip and puts the ball directly into the hip socket.

  In some children, the hip tendon (psoas) also is tight and must be released. Doctors do this by making a small cut through the skin to release the tendon.

• Treatment for children older than 18 months

  Older children usually need surgery to redirect or reshape the bones of the hip, the pelvis or the thighbone so their hips will stay in proper alignment.

  After surgery, your child will wear a special body cast, called a spica cast (PDF), on their hips and legs for about 3 months. The cast will be changed once, midway through the time period.

  After the doctor removes the cast, your child will wear a plastic-and-metal brace to hold the hips in place until X-rays show that the hip socket is normal.
