Thoracolumbar Spinal Stabilization with Three Dimensional-Printed Drill Guides and Pre-Contoured Polyaxial Bone Plates

Authors: Oliver Gilman, Leticia Escauriaza, Dan Ogden, Helene Vandenberghe, Darren Roper, Bill Oxley, Nicolas Granger

Objective: The aim of this study was to report new preoperative and intraoperative techniques performed for canine thoracic or lumbar spine kyphosis stabilization using three-dimensional-printed patient-specific drill guides, polyaxial titanium bone plates and drill stops, and to determine the accuracy of screw placement using these techniques.

Study design: Retrospective study, five client-owned dogs.

Accuracy of Lumbosacral Pedicle Screw Placement in Dogs: A Novel 3D Printed Patient-Specific Drill Guide versus Freehand Technique in Novice and Expert Surgeons

Authors: Jos J Bongers, Nathan Wilkinson, Manabu Kurihara, Janis P Bridges, Wendy Baltzer, Andrew J Worth

Objective: The aim of this study was to compare the accuracy of pedicle screw placement at the canine lumbosacral junction using a novel unilateral three-dimensional printed patient-specific guide (3D-PSG) versus a freehand drilling technique. Additionally, accuracy of screw placement between a novice and an experienced surgeon was determined.
