text: From a biomechanical standpoint, the lumbar intervertebral discs are highly susceptible to herniation because they are exposed to tremendous forces, principally by the magnification of the forces that result from the lever effect of the human arm in lifting; the forces generated by the upper trunk mechanics with rotation, flexion/extension, and side-bending on the discs below; and by the vertical forces associated with the upright position.
