Pediatric Orthopaedic Surgery
World-renowned Patient Care, Teaching and Research in Children’s Orthopaedic Surgery
As chief of the Division of Pediatric Orthopaedic Surgery, I would like to welcome you to our website.
We invite you to explore all the aspects of our division through the various links below and on the side bar. Among other items, you will have the opportunity to get to know our faculty, understand the conditions we treat in detail, read patient testimonials and recognize how you can come prepared to your visit with one of our specialists.
Our growing division currently consists of five faculty members and one fellow, who each have a special area of expertise in addition to practicing general orthopaedics:
Dr. Michael Ain specializes in the treatment of skeletal dysplasias and spinal deformities.
Dr. Paul Sponseller specializes in spine deformity and genetic disorders.
Dr. John Tis specializes in care of the young athlete, including hip arthroscopy.
Dr. Jay Lee specializes in care of the young athlete and pediatric trauma.
Dr. Ranjit Varghese specializes in the treatment of cerebral palsy, neuromuscular disorders and children’s hips and feet.
In addition, each of our faculty members has a nurse practitioner or physician assistant to support their practices. These individuals are also highly trained to administer their own independent practices.
Children’s orthopaedics addresses a whole range of needs. We also have other faculty members in orthopaedic oncology and hand surgery who help us to provide the best care for growing children.
We take pride in our educational mission, having a broad didactic program in which we train residents and medical students from a variety of institutions. Our research endeavors continue to thrive, as we recently published work on identifying risk factors for implant-related fractures and have shown that the hip has by far the highest risk. We have also developed a new technique for pelvic fixation during spine surgery.
