  • Background

    Dr. Flynn is a graduate of Johns Hopkins University and the University of Pittsburgh School of Medicine. He completed his surgical training in the Harvard Combined Orthopaedic Surgery Program, followed by a pediatric orthopedic fellowship at A.I. DuPont Hospital for Children, Wilmington, DE.

    Dr. Flynn has been practicing at The Children's Hospital of Philadelphia (CHOP) since 1996. He is the Associate Chief of Orthopedic Surgery, and Associate Trauma Director for Orthopedics. Dr. Flynn cares for children and adolescents with spine problems, infants and toddlers with hip dysplasia, pediatric fractures, and children with cerebral palsy. He often performs consultations or second opinions on these conditions for families from around the country and from overseas.

    Scoliosis care is Dr. Flynn’s primary clinical and research focus. He pioneered the use of image-guided navigation for pediatric spinal deformity, which significantly improves the safety of implant placement. He has collaborated with other pediatric spine leaders around the country to co-author some of the most important papers and guidelines in spine surgical safety (especially prevention of neurologic injury and infection). Dr. Flynn led CHOP’s effort in the landmark NIH BrAIST trial which conclusively proved the efficacy of back bracing as a treatment for scoliosis.

    Most recently, he has led a complete overhaul of the perioperative process, creating the Scoliosis Rapid Recovery Pathway, which reduces post-operative pain, increases rapid mobilization, and allows patients to return home faster.

    Dr. Flynn is one of a small group of surgeons in the country with a focus on spinal disorders in very young children. He is a member of several international multi-center research networks, including the Harms Study Group, the Growing Spine Study Group, and the Children’s Spine Study Group run by the Children's Spine Foundation.

    Dr. Flynn is a nationally recognized leader in the field of pediatric orthopedic surgery. Currently the president of the Pediatric Orthopaedic Society of North America, Dr. Flynn has published more than 180 peer-reviewed scientific articles, reviews or textbook chapters. He has written or edited the seminal textbooks of pediatric orthopedics (Lovell and Winter’s Pediatric Orthopaedics), pediatric fracture care (Rockwood and Wilkins' Fractures in Children), and pediatric orthopedic surgical techniques (Operative Techniques in Orthopaedic Surgery). He is also editor of the primary book used for medical board review and maintenance of certification in orthopedics (AAOS Orthopaedic Knowledge Update 10).

    Dr. Flynn lectures nationally and internationally on pediatrics fractures and spine disorders and safety in pediatric orthopedics. He co-chairs the International Pediatric Orthopaedic Symposium, and leads the Continuing Medical Education Courses Committee for the American Academy of Orthopaedic Surgeons.
