PODCAST: The Limping Child

05.09.25

Limping is a common complaint in pediatric emergency care, but the differential is broad and the stakes are high. In this episode, we walk through a detailed, age-based approach to the evaluation of the limping child. You’ll learn how to integrate the Kocher criteria, when imaging and labs are truly necessary, and how to avoid being misled by small joint effusions on ultrasound. We also highlight critical mimics like appendicitis, testicular torsion, and malignancy—and remind you why watching a child walk is one of the most valuable parts of the exam. Whether it’s transient synovitis, septic arthritis, or something much more concerning, this episode gives you the tools to manage pediatric limps with confidence.

Learning Objectives

Apply an age-based approach to the differential diagnosis of limping in children.
Demonstrate diagnostic reasoning by integrating history, physical exam, imaging, and lab findings to prioritize urgent conditions like septic arthritis and SCFE.
Appropriately select and interpret imaging and lab studies, including understanding the utility and limitations of ultrasound, MRI, and the Kocher criteria.
