Effect of Coating

The Pullout Performance of Pedicle Screws
17 Mar 2015

Abstract

Bone Formation Bone Tissue Contact Surface Lumbar Spine Pedicle Screw
Interface conditions affect the pullout strength of the screw. It is important to have a bonded surface rather than a contact surface between pedicle screw and the vertebrae. For this reason, pedicle screw can be coated with bounding materials to ensure this interface and avoid the screw failures. That explains why the screws are coated with bioresorbable materials to increase the holding strength of the pedicle screws.
