Challenges and perspectives for internal radiation exposure examinations using the whole-body counting system following the Fukushima Daiichi nuclear power plant accident.

Every other year, the Pediatric Orthopaedic Society of North America (POSNA) selects and sends three of its members to serve as traveling fellows in various European cities. In addition to a robust exchange of clinical experiences and research ideas, this traveling fellowship offers fellows the opportunity to gain valuable insight into novel operative techniques, to see cohesive systems that better support patient care, and to develop transnational collaborations. Most importantly, it provides the mental space and time to “talk orthopaedics,” to explore big ideas, and to create meaningful friendships. In the spring of 2026, the POSNA traveling fellows were Benjamin Sheffer of the Campbell Clinic in Memphis, TN, Verena Schreiber of Cincinnati Children's Hospital, and Rachel Thompson of Rady Children's Hospital in San Diego, CA (). Over 3 weeks, we shared in the opportunity of a lifetime as we traveled to multiple sites in the Netherlands, Belgium, and Sevilla, culminating in our participation in the European Paediatric Orthopaedic Society (EPOS) Annual Meeting. We had a wonderful time together and with all of our gracious hosts. We are deeply grateful to the members of POSNA, EPOS, and our European host sites for this wonderful opportunity. We submit this summary of our experience in the hope that it inspires the next cohort of POSNA members to seek out this incredible opportunity. Dr. Benjamin W. Sheffer, MD, Campbell Clinic Orthopaedics; Dr. Verena M. Schreiber, MD, Cincinnati Children's Hospital; and Dr. Rachel M. Thompson, MD, Rady Children's Hospital
