Researchers from the Barrow Neurological Institute in Phoenix, Arizona studied the five models for use in training with simulation of both Freehand and Percutaneous Pedicle Screw Placement, with all models evaluated and then scored by junior and senior residential spine surgeons. All 3D Printed Barrow Biomimetic Spine model were created with Meshmixer software, imported back into Simplify3D software, and then 3D printed on a FlashForge Creator Pro with an affordable cost of $50-$70.
