Disc Replacement, Lumbar (Charite'©)


This surgical procedure replaces a damaged or diseased disc in the lumbar spine with an artificial disc that restores the natural alignment of the spine. Unlike fusion surgery, which causes the vertebrae above and below the problem disc to grow together into a single bone, the artificial disc preserves spine motion at that level.


After anesthesia is administered and the patient is positioned, the surgeon creates a small incision in the abdomen to access the lumbar spine.

Clearing the Vertebrae

The surgeon carefully removes the problem disc material and prepares the surfaces of the vertebrae for the artificial disc.

Inserting the Endplates

The implant's metal endplates are positioned between the vertebrae. Tiny teeth on the upper and lower plates hold them in place.

Inserting the Core

The polyethylene core is inserted and seated between the endplates. The core's smooth surfaces will allow the adjoining vertebrae to twist and bend.

Securing the Implant

The spine is returned to normal posture, restoring its proper height and alignment. This fully seats the endplates in the vertebrae bones and secures the sliding core.

Pressure Relieved

Pressure from pinched nerve roots may be reduced which may relieve chronic pain in the legs. Removal of the painful disc relieves chronic back pain from degenerative disc disease.

End of Procedure and Aftercare

The incision is closed and bandaged. The patient will return home after a brief stay in the hospital, typically lasting for one to three days. The surgeon will determine the length of the hospital stay and will guide the post-operative recovery. Physical therapy may be needed.
