Degenerative spine conditions involve the gradual loss of normal structure and function of the spine over time. They are usually caused by aging, but may also be the result of tumors, Discitis (Inflammation of the intervertebral disc), Scoliosis, infections or arthritis. Pressure on the spinal cord and nerve roots caused by degeneration can be caused by:

• Slipped or herniated discs 
• Spinal stenosis, or narrowing of the spinal canal
• Osteoarthritis, or breakdown of the cartilage at the spinal joints

The lumbar vertebrae and disks are at the bottom of your spine. Disc between the vertebrae work like cushions to allow the vertebrae to rotate and move without the bones rubbing against each other. In lumbar disc replacement a team of surgeons (usually a vascular surgeon and an orthopedic or neurosurgeon) will do the procedure together. The surgeon will make an incision in your abdomen. Your organs and blood vessels will be moved to the side to allow access to your spine. The surgeon will remove and replace a worn or degenerated disc in the lower part of your spine with an artificial disk made of metal or a combination of metal and plastic. Your organs and blood vessels are put back in place and the incision will be closed.
