Fig. 2From: Effect of pedicle screw augmentation with a self-curing elastomeric material under cranio-caudal cyclic loading—a cadaveric biomechanical studyTest setup of the material testing machine. Green arrows indicate the degrees of freedom while the cranio-caudal load (red arrow) is applied. A 3D motion analysis system is fixed to the base plate as well as the pedicle screw headBack to article page
