Entire Team Engaged in Pediatric Orthopedic Research

Our international reputation of excellence in pediatric orthopedics is built on our commitment to research. In fact, 100 percent of our faculty is involved in research and education. And every year, our Department of Orthopedics trains three to four surgeons, who often come from other countries to learn from our advanced, in-the-field approach to conducting research.

With two PhD-trained researchers supporting the department, our research covers a breadth of orthopedic conditions. And members of our department are associated with multicenter research projects — presenting our findings and studies all over the world.
