Sciatica / Slipped Disc

Injury or weakness can cause the inner jelly like portion of the disc to protrude through the outer ring. This is known as a slipped or herniated disc. This causes pain and discomfort. If the slipped disc compresses one of your spinal nerves, you may also experience tingling, numbness and pain along the affected nerve. As the lumbar spine (lower back) carries most of the body weight, it tends to “slip” more than higher levels.

Presentation Transcript

  1. What is a slipped disc?  Injury or weakness can cause the inner jelly like portion of the disc to protrude through the outer ring.  This is known as a slipped or herniated disc.  This causes pain and discomfort. If the slipped disc compresses one of your spinal nerves, you may also experience tingling, numbness and pain along the affected nerve.  As the lumbar spine (lower back) carries most of the body weight, it tends to “slip” more than higher levels.

  2. What is the anatomy of disc herniation / herniated disc/ slip disc /sciatica?  Human Spine is made of up 33 bones (vertebrae) that are cushioned by discs.  These vertebrae are divided by region: neck (cervical spine), mid-back (thoracic spine), and low back (lumbar spine).

  3. At the lower end of your spine, you also have the sacrum and the coccyx, which is commonly called your tailbone.  Discs are present between these bones.

  4.  The disks protect the bones by absorbing the shocks from daily activities like walking, lifting, and twisting. Each disc has two parts—a soft, gelatinous inner portion (nucleus pulpous) and a tough outer ring (annulus fibrosus) . Together, the vertebrae and discs form a tunnel through which the spinal cords and nerve pass.
