Abstract

Pedicle screw has a role in stabilizing vertebral bone motion and resisting all types of load such as axially load. If pedicle screw cannot maintain axially load that happened, pull out failure can be occurred. Experimental pedicle screw pull out testing is referring to American Society for Testing and Materials (ASTM) F543. Each pedicle screw displaced at 5 mm/min until pedicle screw pulled from the test block material. Note the displacement graph between load and displacement, and the highest peak means maximum pull out force of the specimen. The purpose of this study to determine the maximum axially force of pedicle screws can bear. Commercial 1 pedicle screw shows higher pull out maximum force with 1497 N than commercial two pedicle screw with 469 N.
