Dr. Ebraheim’s educational animated video describing disc herniation of the lumbo sacral spine, the etiology, signs and symptoms, diagnosis , and treatment options. The spine is comprised of bony vertebrae separated by discs. Spinal cord ends at level of T12-L1. Conus Medullaris is the lower end of the spinal cord. Cauda Equina is a division of multiple nerve roots beginning at the level of L1. Conditions of the lumbar spine including disc herniation are a main cause of low back pain. The lumbar spine (lower back) consists of five vertebrae numbered L1 to L5. These vertebrae are attached to the sacrum at the lower end of the spine. The discs between the vertebrae are round cushioning pads which act as shock absorbers. Inner disc layer is soft gelatinous tissue (Nucleus Pulposus). Outer disc layer is thick and strong tissue (Annulus Fibrosus). A disc herniation of the lumbosacral region could involve the nerve roots. In 95% of all disc herniation cases, the L4-L5 or L5-S1 disc levels a
