If your child has been diagnosed with hip dysplasia, you're no doubt feeling anxious. The orthopedic specialty team here at Cook Children's understands this. That's why we work with you to determine the best treatment plan for your child. Like you, our goal is to help ensure your child can have the best care and outcome possible.
Developmental dysplasia of the hip (DDH) is a problem with the way a baby's hip joint forms. Sometimes the condition starts before the baby is born, and sometimes it happens after birth, as the child grows. It can affect one hip or both.
Most infants treated for DDH develop into active, healthy kids and have no hip problems.
The hip joint is a ball and socket joint. The top part of the thighbone (the ball part of the hip) sits inside a socket that's part of the pelvic bone. The ball moves around in different directions, but always stays inside the socket. This lets us move our hips front, back, and side to side. It also supports our body weight for walking and running.
In DDH, the hip does not form well. The ball part of the joint may be completely, or partly, out of the socket. Sometimes the ball part may slide in and out of the socket. Often, the socket is shallow. If this is not fixed, the hip joint will not grow well. This can lead to pain with walking and hip arthritis at a young age.
Any baby can have DDH, and we can't always be certain of the causes. However, there's a higher chance of being born with DDH in babies who:
Rarely, a baby isn't born with DDH, but develops it after birth. To prevent DDH in babies who aren't born with it, don't swaddle a newborn's hips or legs tightly together. Always make sure a baby's legs have plenty of wiggle room.
Developmental dysplasia of the hip doesn't cause pain in babies, so can be hard to notice. Doctors check the hips of all newborns and babies during well-child exams to look for signs of DDH.
Parents could notice:
Babies with any of these signs should see a doctor to have their hips checked. Finding and treating DDH early usually means there's a better chance for a baby's hips to develop normally.
Many babies are born with hips that feel loose when moved around. This is called neonatal hip laxity. It happens because the bands of tissue that connect one bone to another, called ligaments, are extra stretchy. Neonatal hip laxity usually gets better on its own by 4–6 weeks of age and is not considered true DDH.
A baby's whose hip ligaments are still loose after 6 weeks might need treatment. So follow-up doctor visits for babies with hip laxity are important.
Doctors find most cases of DDH during well-child exams. If a baby has signs of DDH or has a higher risk for it, the doctor will order tests.
Two tests help doctors check for DDH:
A pediatric orthopedic surgeon (a specialist in children's bone conditions) cares for babies and kids with DDH. The goal of care is to get the ball of the hip in the socket and keep it there, so the joint can grow normally.
The orthopedic surgeon chooses the treatment based on the child's age. Options include:
A brace or cast will hold the hip in place and will be on both sides, even if only one hip is affected.
Treatment for babies younger than 6 months old usually is a brace. The brace used most often is a Pavlik harness. It has a shoulder harness that attaches to foot stirrups. It puts the baby's legs into a position that guides the ball of the hip joint into the socket.
Treatment with the Pavlik harness often lasts about 6–12 weeks. While wearing the harness, the baby has a checkup every 1–3 weeks with hip ultrasounds and exams. During the visit, the medical team can adjust the harness if needed.
The harness (brace) usually works well to keep the hips in position. Most babies won't need other treatment.
Rarely, the harness isn't able to keep the ball of the hip in the socket. Then, doctors might do either:
A child might need a closed reduction if:
For a closed reduction, the baby gets medicine (general anesthesia) to sleep through the procedure and not feel pain. The surgeon:
Sometimes, the orthopedic surgeon also loosens the tight muscle in the groin during the closed reduction.
A child might need surgery (an open reduction) if:
Sometimes, the orthopedic surgeon also does a surgery on the pelvic bone to deepen a very shallow hip socket, especially for a child older than 18 months.
Kids will have regular checkups with their orthopedic specialist until they're 16–18 years old and done growing. These help make sure the hip develops well.
