Stability of a spinal motion segment comes from tissues that resist motion and keep alignment, such as the disc and its annulus fibrosus, and the supporting ligaments like the ligamentum flavum and the posterior longitudinal ligament. The annulus fibrosus is the tough outer ring of the intervertebral disc that resists torsion and shear, helping hold vertebral bodies together. The ligamentum flavum connects adjacent laminae and becomes taut with extension, contributing passive stiffness and helping control motion. The posterior longitudinal ligament runs along the back of the vertebral bodies inside the spinal canal, restricting excessive flexion and supporting the posterior aspect of the segment. The intervertebral foramen, however, is simply the opening for exiting nerve roots; it isn’t a structure that stabilizes the motion segment.
