WebFeb 9, 2024 · As it was recently noted, the most commonly employed method of managing both post-traumatic and rheumatic craniovertebral dislocation is Goel-Harms C1 lateral mass-C2 pedicle screw placement [6, 7]. This procedure has become a gold standard thanks to polyaxial screws that provide a solid bicortical purchase. WebA custom-made biomechanical setup was used to test the specimens with a C1/C2 Harms construct each with the use of lateral mass screws and pedicle screws in sequence. Strain gauges were used to analyse the bending forces from C1 to C2 in cyclic axial compression (μm/m). All underwent cyclic biomechanical testing using 50, 75 and 100 N.
