Dr. Jennifer Bauer from Seattle Children’s Hospital is our special guest on this episode in which we discuss her recent randomized controlled trial which tested the effect of pre-operative carbohydrate drink on post-operative return of bowel function in pediatric spine fusion patients. This episode also highlights some recent work looking at the reversibility of hemiepiphysiodesis after PETS technique, a multicenter study of short versus long leg casting for distal tibial physeal fractures, and a 3D study of the distal femoral physis. Your hosts are Tyler McDonald from University of South Alabama, Craig Louer from Vanderbilt, and Julia Sanders from Children’s Hospital Colorado. Music by A. A. Aalto.

The Pediatric Spine Study Group (PSSG), Scoliosis Research Society (SRS), and POSNA collaborate in this episode about new technology in spine surgery, including navigation, robotics, AI, 3D-printed screw guides, patient-specific rods, and more. Your hosts Carter Clement (Children’s New Orleans), Dominick Tuason (Yale), and Anthony Catanzano (Duke) lead a discussion with an esteemed panel of pediatric spine surgeons including Mark Erickson (Colorado Children’s), Chris Hardesty (Rainbow Babies and Children’s), Jason Anari (CHOP), Jaysson Brooks (TSRH), and David Skaggs (Cedars-Sinai). Panelists discuss their individual work flows, learning curves, and pearls/pitfalls for new adopters.
