This is a special combined episode of the POSNA Peds Ortho and PRISM Pediatric Sports Lab podcasts which recaps the 2026 PRiSM Annual Meeting held in Austin, TX. It features AMSSM exchange speaker Dr. Jason Zaremski and Keynote Speaker Dr. John DiFiori.

Dr. Kevin Klingele, fellowship director and chief of pediatric orthopaedics at Nationwide Children’s, joins the show to discuss his recent research on ligamentum teres reconstruction. As an interlude, Dr. Dan Perry also returns to the podcast to provide an update on the SCIENCE Trial, comparing surgery and non-surgical care for children with displaced medial epicondyle fractures. Your hosts are Carter Clement from Manning Family Children’s in New Orleans, Will Morris from TSRH, Tyler McDonald from USA, Stephanie Logterman from the Arnold Palmer Hospital for Children, and Josh Holt from Iowa. Music by A.A. Aalto.

Deep Dive in DDH is a three-part limited series where experts in the field of DDH have been invited to discuss the controversies in the management of hip dysplasia. Episode 1 was published in August and discussed management of DDH in infants under 6 months of age. In Episode 2, we are joined by Eduardo Novais at Nemour Children’s Health in Jacksonville and Salil Upasani of Rady Children’s Hospital and discuss the controversies in the management of developmental hip dislocations in the operating room including the process to decide between closed and open reduction, the use of concomitant osteotomies, adjunctive imaging, and casting protocols.
