2015 ACVIM Forum Research Abstract Program

21 Beagle dog cadavers were randomly assigned 1 of 3 stabilization techniques including transarticular screw fixation (TSF) and 2 multi-implant constructs (MI5 or MI6) respectively composed of 5 or 6 screws embedded in polymethyl-methacrylate cement. All screws were placed based on a separate study defining ideal implant placement in Beagles (unpublished data) using a new drill guide prototype designed to improve accuracy of implant placement. C1-C2 spinal segments were then extracted and computed tomography images were obtained to assess for anatomical reduction and safety of implant placement. Ventral flexion bending moment at failure and stiffness of the constructs were subsequently determined and compared between groups.
