Artificial disc products that are in development or in use are typically intended for use in patients with the following indications:
Diagnosis of degenerative disc disease (typically at a single level)
Are between the ages of 18 and 60
Suffer from low back pain as the major complaint (rather than leg pain)
Have not responded to a minimum of six months of conservative treatments (such as physical therapy, pain medications)
Are candidates for spine surgery (such as a lumbar fusion)
Overall, the current indications for implantation of an artificial disc are quite similar to indications for lumbar spine fusion.
