Pull out tests of the spinal screws

Project description:

The MTS system-screw fixation

Pull out test

Preparing the specimen

Screw after the pull out test

Different types of commercial fixation screws (Aesculap, Johnson & Johnson, Medtronic) used for back-side surgical treatment were tested. Furthermore, the comparative study of pull out analysis and the results evaluation was performed. The main goal was the determination of safe screw anchorage in the artificial bone and the investigation of strenght fixation. Profound experimental measurements were carried out in the Laboratory of biomechanics CTU in Prague. The achieved outputs will be used in the clinical practice thanks to the cooperation with FH Motol.
