A lumbar disk replacement is typically used to treat those that are experiencing severe issues in their lower back. After running the appropriate tests, your doctor will discuss the results and decide if this type of surgical intervention is necessary for you. You may be a candidate for a lumbar disk replacement if: • You have severe back pain caused by specific disks in your lower spine • You don’t have joint disease • You don’t have nerve compression in your spine • You’re not significantly overweight • You haven't had spinal surgery before • You don’t have scoliosis • You don’t have a spinal deformity
