Ask the MSK Expert: What is bi-level disc replacement and who is a candidate?


What is bi-level disc replacement and who is a candidate?

Dr. Rainey says: “Disc replacement surgery refers to removing a disc from the cervical spine that is pinching either the spinal cord or a nerve and replacing that disc with a mobile joint. Traditionally, this type of problem – a disc herniation in the neck – is treated surgically by removing the disc and replacing it with a spacer that fuses the spine, which causes limited movement. By replacing the disc with a mobile joint instead, motion in the neck is maintained, and a patient recovers more quickly.

“Patients with symptoms of arm pain, numbness or weakness resulting from a pinched nerve in the neck may be candidates for the procedure when nonoperative treatment has failed. Bi-level disc replacement refers to this procedure being performed at two different levels to address two different disc herniations; it is also performed as a one-level procedure.”
