Why you might a lumbar disc replacement

Vertebrae and discs are what make up the spine. The vertebrae are bones stacked on each other, while the discs in the middle of each vertebra are like cushions that permit the movement and rotation of vertebrae without them pressing on each other. Located in the lower spine are the lumbar vertebrae and discs.

You can be a good candidate for the surgery if the pain you are feeling is located in the lower spine (particularly in one or two discs); you are not obese or overweight excessively; you do not have any significant joint disease or nerve compression on your spine; you did not undergo any previous surgery on your spine; and you do not have any spinal deformity such as scoliosis.
