About ProDisc-L

The ProDisc-L Total Disc Replacement device is intended to treat a single degenerated (diseased) disc in the lower spine (L3-S1). The ProDisc-L implant was designed in collaboration with practicing spine surgeons and has been thoroughly tested in both laboratory and clinical settings.


The ProDisc-L implant allows the potential for motion through its ball and socket design.

  • A plastic inlay affixed to a bottom metal endplate forms the ball.
  • A polished concave metal surface in the top endplate forms the socket.
  • The socket can move over the surface of the ball to allow for controlled and predictable motion.



The ProDisc-L implant is secured to the bones (vertebrae) in the spine with a patented central keel on the top and bottom endplates. A coating has also been applied to all the implant surfaces that contact bone to allow for the bone to grow onto the implant.

Clinical History

The ProDisc I implant, the predecessor of the ProDisc-L implant, was first implanted in 1990. The ProDisc-L implant that is used today was introduced outside the United States in 1999. It was approved by the Food and Drug Administration (FDA) for use in the United States in August 2006.

A ProDisc-L IDE clinical study evaluated the ProDisc-L Total Disc Replacement surgery compared to spinal fusion surgery*. The study demonstrated that ProDisc-L surgery is a safe and effective alternative to fusion surgery* for qualified patients.

*The ProDisc-L surgery was compared to a “Circumferential” fusion surgery, which involves removing the diseased disc and inserting a disc spacer through an incision in the abdomen and attaching metal screws and rods to the back of the spine through incision(s) in the back.
