Types of disc replacement
Artificial disc replacement is typically categorized based on the location in the spine where the pain is felt. If the pain is in the upper part of the spine, neck, or arm, cervical disc replacement is used to replace the problematic discs. However, if the pain is in the lower part of the spine or lower back, your doctor might recommend lumbar spine disc replacement. Both treatments are modern alternatives to spinal fusion, a treatment that relieves pain but may limit a person’s ability to fully turn their neck or make movements that reply on the spine. Cervical and spinal disc replacement are designed to address pain without limiting spinal flexibility.
Cervical disc replacement surgery, also referred to as cervical disc arthroplasty, is a modern approach to addressing issues with discs in the upper spine that cause pain, numbness, or weakness due to pressure on the spinal cord or nerves. Unlike traditional methods that involve fusion, this procedure involves replacing the damaged disc with an artificial one to maintain neck motion and reduce stress on nearby vertebrae.
Lumbar disc replacement is a surgical procedure that treats issues in the lower part of the spine, specifically the lumbar vertebrae and discs. These discs serve as natural cushions between the vertebrae, making it easier to move and preventing bone-to-bone friction. This surgery becomes necessary when a disc in the lumbar region becomes worn or degenerated, causing pain and impairment.
