Artificial disc replacement surgery involves replacing a painful disc with an artificial disc. Artificial disc surgery may be performed on the lower back (lumbar spine) or the neck (cervical spine). Artificial discs are designed with the goal of mimicking the form and function of the spine's natural disc.

The spinal disc can cause pain in a number of ways, including degenerative disc disease or a herniated disc (sciatica). This article discusses the role of the spinal disc and how an injury to the disc can cause pain.

A 2-level cervical disc replacement addresses 2 adjacent offending cervical spine discs by replacing each with an artificial disc device.
