Send me feedback and comments. Feel free to ask me questions about the technique. The posterior disc space increases in height.
Flexion decreases disc protrusion and reduces stenosis.
Discs protrude and degenerate into the concavity of a curve, into the side of extension. Flexion stretches the ligamentum flavum to reduce stenosis. Flexion increases metabolite transport into the disc. Flexion opens the apophyseal joints and reduces posterior disc stress. The nucleus pulposus does not move on flexion.
