Why Choose CHOP for Hip Disorder Treatment

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

CHOP has consistently ranked among the top five pediatric hospitals in the United States for orthopaedic care. Our surgeons perform some of the most complex orthopaedic 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.

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


CHOP is a national leader in research on most pediatric hip conditions. Areas of active research include the development of novel imaging protocols for children’s hips, optimizing the management of slipped capital femoral epiphysis, understanding the natural history of mild childhood dysplasia, the cause of hip problems in Trisomy 21 (Down syndrome), and the genetic factors responsible for pediatric hip disease.

In addition to the research being done at CHOP, our surgeons are key members of several multi-center research groups, including the International Perthes Study Group (IPSG), the International Hip Dysplasia Institute (IHDI), and the Academic Network of Conservational Hip Outcomes Research (ANCHOR).
