Intervertebral discs are pads of fibrous tissue and cartilage that are found between two vertebrae.
They help to cushion the jerks felt by the spinal cord during walking, running and other activities. The discs may in some cases protrude into the spinal canal. In severe cases, the protruded disc can press on a nerve and cause pain or other symptoms. Mild cases of disc protrusion require no treatment. Only physiotherapy may be needed to strengthen the back muscles. Intermittent traction may also be required. Severe cases of disc protrusion may require surgery to remove the portions of the disc that are protruding into the spinal canal.
