Lumbar Spine Pathology Intervertebral Disc Protrusion neuro-surgeon videos. Shows a lateral and a superior cross-sectional view of a cervical inter-vertebral disc protrusion. The nucleus pulposus degenerates, increasing pressure on the annulus fibrosus. Annulus micro-tears occur and weaken the disc wall, resulting in the nucleus pulposus protruding into the annulus fibrosus. The annulus bulges and irritates the adjacent spinal cord and nerve root. <br />When you sit, stand up, bend or twist, large compressive forces are applied to your spine. There are several factors that determine the ability of your inter-vertebral discs to handle these forces: <br /> your inherited make-up<br /> disc health - worsened by smoking, poor nutrition, sedentary lifestyle, weak muscles, and obesity<br /> ageing<br /> poor posture - while sitting, standing and lifting<br /> heavy loads during home, work.<br />Visit http:/www.medilaw.tv for more information.
