Disc Replacement, Lumbar
The disc replacement surgical procedure replaces a damaged or diseased disc in the lumbar spine with an artificial disc to restore the natural alignment of the spine.
After anesthesia is administered, the surgeon creates a small incision in the abdomen to access the lumbar spine. The surgeon carefully removes the problem disc material and prepares the surfaces of the vertebrae for the artificial disc. The upper and lower sections of the implant are placed together and positioned between the vertebrae. The spine is returned to normal posture. The implant restores the spine to its proper height and alignment.
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.
With this surgery, pressure from pinched nerve roots may be reduced and may relieve chronic pain in the legs. Removal of the painful disc relieves chronic back pain from degenerative disc disease.
