International Perthes Study Group

The International Perthes Study Group is a group of specialists and researchers with a common goal of advancing knowledge and care of patients with Legg-Calvé-Perthes disease. Tim Schrader, MD, a pediatric orthopedic surgeon at Children’s, was a founding member of this group and is actively involved in collaborative studies with researchers across the world.

Children's Spine Foundation and Study Group

The Children’s Spine Foundation is a community dedicated to improving the quality of care and outcomes for patients and families dealing with chest wall and spine deformities. Children's works with the Spine Study Group on research projects to help improve patient outcomes. Michael Schmitz, MD; Nicholas Fletcher, MD; and Joshua Murphy, MD, all pediatric orthopedic surgeons at Children’s, are actively involved in this collaboration.

Harms Study Group

Children's is one of only 25 centers that participate in this invitation-only research group. In an effort to standardize post-operative spinal fusion care, the team has provided research and data collection from the Children’s spinal fusion post-operative pathway. This research helps to guide best practices nationwide with the goal of improving spinal fusion patient outcomes. Dr. Fletcher provides leadership on behalf of Children’s in this collaboration with the Harms Study Group.

Research in Osteochondritis Dissecans of the Knee (ROCK)

The Research in Osteochondritis Dissecans of the Knee (ROCK) group is committed to developing improved methods for the diagnosis, evaluation and treatment of osteochondritis dissecans. Our team works closely with other members of this group to identify better treatment plans for patients. Michael Busch, MD; S. Clifton Willimon, MD; and Dr. Perkins represent Children’s through research efforts in this group.

Function After Adolescent Clavicle Trauma and Surgery (FACTS) Multicenter Study Group

Children’s is one of eight centers nationwide that participate in the FACTS Study Group. These centers represent the highest-volume pediatric hospitals in the country that are combining their clinical experience to determine treatment outcomes for teenagers who have displaced clavicle fractures. Drs. Busch, Willimon and Perkins contribute to this group.

Pediatric ACL: Understanding Treatment Options (PLUTO)

PLUTO is a national study group investigating the safety and effectiveness of treatment of pediatric anterior cruciate ligament (ACL) injuries, specifically in children with open growth plates. Children’s sports medicine surgeons, including Drs. Busch, Willimon and Perkins, are active members of this group.

Pediatric Research in Sports Medicine (PRiSM)

PRiSM is devoted to the care of pediatric and adolescent athletes. Many pediatric sports injuries and conditions are unique to young athletes and do not occur in other age groups. By combining research across multiple centers and different practitioners, the group aims to increase the impact of research. Drs. Busch, Willimon and Perkins participate in this study group and lead research interest groups studying complex knee injuries and shoulder instability.

Multicenter Pin Site Infection Study

Jill Flanagan, MD, a pediatric orthopedic surgeon at Children’s, is actively involved in the Multicenter Pin Site Infection Study led by British Columbia Children’s Hospital. It aims to measure and document pin site infection rate and pin site care across Canada, the U.S. and United Kingdom through a multicenter pin site infection database. By identifying the factors contributing to pin site infections, this study will take another step toward improving clinical care for children in external fixation devices.

Multicenter Study Group for Pediatric Limb Deformity

This study group, led by University Hospitals Cleveland Medical Center, is committed to establishing a multicenter prospective study group to define the appropriate indications and expected outcomes in children treated for pediatric limb deformity. The establishment of this large coalition, including Dr. Flanagan, will offer substantial improvements to the current literature and ultimately make a significant impact in our care of children with these conditions.

CORTICES Trauma and Infection Study Group

CORTICES is a collaboration of pediatric orthopedic surgeons dedicated to improving quality, safety and value in the management of emergent orthopedic conditions through education, research and development of optimal care guidelines. Dell McLaughlin, MD, as well as Drs. Fletcher and Murphy, help lead research efforts on behalf of Children’s in this group.
