Predicted locations of the center of rotations (ICR) and the resulting pressure distribution in the inferior facet of L4 with increasing extension. Explanations for the ICRs see Fig. 4. The maximum forces for each facet joint and the pressure distribution are shown for moments of 1.5, 3.75, and 7.5 Nm.
