Hip Disorders Program

The Hip Disorders Program at The Children's Hospital of Philadelphia developmental-dysplasia-hip
Developmental dysplasia of the hip is just one of the conditions treated by the expert orthopedics team at CHOP.
specializes in the diagnosis and treatment of all pediatric hip disorders.

Whether your child is a premature infant with a congenital hip deformity, a teen with a newly-developed hip problem or a young adult with lingering effects of pediatric hip disease, our specially-trained orthopedic team has the expertise and experience needed to produce the best outcomes.

Each year, we treat hundreds of children, teens and young adults — from the region and beyond — with congenital, developmental and post-traumatic hip disorders.

Why choose us

Innovation and expertise of our multidisciplinary team

Led by orthopedic surgeons Wudbhav N. Sankar, MD, Richard S. Davidson, MD, B. David Horn, MD, and Lawrence Wells, MD, CHOP’s Hip Disorder Program is one of the largest and most comprehensive pediatric hip programs in the country.

Our surgeons perform some of the most complex orthopedic surgical procedures in the world. We have special expertise in hip conservation in adolescents and young adults to stop continued damage to bone and cartilage and prevent the need for premature hip replacement.

Traditional hip treatment — developed for adult patients — is not always the best option for a child. Treating bone issues in children is more complex than with adults with the same condition.  Children's bones are still growing and lengthening; their growth plates have not fully fused. That’s why it is important to seek out orthopedic experts who are specially trained to work with a child's unique physiology. 

All four surgeons in CHOP’s Hip Disorders Program have extensive training and experience in pediatric orthopedics. 

In addition, Dr. Sankar completed a second specialized fellowship in adolescent hip surgery. He is the only physician in the region performing certain specialized hip surgeries on adolescents and young adults.

Some of the specialized procedures available at CHOP include:

Our multidisciplinary team of surgeons, radiologists, advanced practice nurses and others consider all possible treatment options for children, adolescents and young adults with hip disorders. If surgery is needed, our team works with pediatric anesthesiologists and pain specialists to make surgery as safe and comfortable as possible.

Integrated care to provide the best outcomes

The Hip Disorders Program offers complete care for children, teens and young adults with a hip defect or injury — from evaluation, to treatment and long-term follow up.

We offer a full spectrum of diagnostic testing. Along with standard imaging technologies (MRI, CT scans and X-rays), the Hip Disorders Program at CHOP also uses individualized, disease-specific MRI protocols that include cartilage mapping technology. By better visualizing the entire hip, our clinical team can provide a more accurate diagnosis and help guide surgical treatment if needed.

At CHOP, your child will also have access to resources and experts in other pediatric specialties should they be required. The Hospital shares the No. 1 spot on U.S. News & World Report's 2014-15 Honor Roll of the nation's Best Children's Hospitals, and CHOP's orthopedic care has consistently ranked among the top five in the country.

We examine and follow patients with hip disorders at several locations in Pennsylvania and New Jersey. See our locations to find an office near you. 

If surgery is needed, it will take place at CHOP's Main Campus in Philadelphia. In most cases, your child will stay in a private or semi-private hospital room until he or she has recovered from surgery. If your infant, child or teen needs more acute care because of an underlying medical condition, he or she will stay in our award-winning Neonatal/Infant Intensive Care Unit or Pediatric Intensive Care Unit

Research into disease origins and better treatments

Orthopedic clinicians at The Children's Hospital of Philadelphia are actively researching a range of hip disorders. Orthopedic doctors regularly collaborate with The Center for Applied Genomics at CHOP, one of the world's largest genetics research programs and the only center at a pediatric hospital to have large-scale access to state-of-the-art throughput genotyping technology.

CHOP is also a major contributor to collaborative orthopedic research on a national and international scale. Our orthopedic surgeons are members of the Academic Network of Conservational Hip Outcomes Research (ANCHOR), the International Perthes Study Group and the International Hip Dysplasia Institute. Each study group is comprised of leading surgeons and researchers who have pioneered and studied methods for hip preservation surgery in patients with a variety of hip disorders.

Current hip research at CHOP includes:

With research, orthopedic leaders at CHOP hope to be able to better predict hip conditions and treat them before many of the symptoms begin.
