Cervical Spine Pathology Intervertebral Disc Protrusion medical legal 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. 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:
your inherited make-up
disc health - worsened by smoking, poor nutrition, sedentary lifestyle, weak muscles, and obesity
ageing
