Mechanical Performance of PRIMA OCT System under Interconnection Testing and Corpectomy Testing
The fixation of the vertebral column using transpedicular screws is a well-establish technique. Multi-axial pedicle screw designs allow deviation of the screw away from the perpendicular to the longitudinal rod, which facilitates application of a screw-rod system such as PRIMA OCT into the curved spine. This study was performed a static (compression bending and torsion) and dynamic (compression bending fatigue) empirical analysis of PRIMA OCT component such as pedicle screw, rod and set screw based on the guideline of ASTM F136-98 using Ultra-high Molecular Weight Polyethylene (UHMWPE) blocks as test vertebral bodies.
