ISO 12189 Dynamic Pedicle System Test Model. Light gray: PE (polyethylene) block simulates vertebral body, blue: connecting rod implant with dynamic section (black spring), dark gray: pedicle screw, red spring: calibration spring simulates intervertebral disc. The test is performed under sinusoidal load with a maximum test frequency of 5 Hz. This force, in turn, depends on the position of the spine to be modeled. (lumbar spine: 0.6-2.0 kN / neck: 0.05-0.15 kN). The test ends when 5 million duty cycles are reached or when the structure has a mechanical failure. The results of the fatigue test must be summarized with an S-N curve. These tests are performed at ambient temperature, but can also be repeated in a Ringer's solution at 37 °C if necessary to simulate physiological environmental conditions and determine possible corrosion effects.
