Pullout Analysis of a Lumbar Plate With Varying Screw Orientations: Experimental and Computational Analyses
Spine, 07/16/2012
Rios D et al. – Significant difference was found between certain screw–angle configurations; however, when compared with simply placing the screws straight in, the difference was never more than 8%. This implies that there is greater freedom in the angle and placement of screws than previously thought. The results show that there is little change in fixation strength when placing the screw in a different direction.
