Back Surgery Studies Encouraging
By Shanida Smith, Ivanhoe Health Correspondent
LOS ANGELES (Ivanhoe Newswire) -- Researchers say ongoing studies on artificial disc replacement surgery are encouraging. John Regan, M.D., an investigator and orthopedic surgeon from Cedars-Sinai Medical Center in Los Angeles, says, "Early results are very promising."
Artificial disc replacement surgery involves the insertion of a small circular implant between the vertebrae. The disc is made up of three components: two steel outer layers that adhere to the vertebrae and a plastic center. This three-layer design allows maximum flexibility.
Dr. Regan adds, "People are very interested in this as opposed to spinal fusion." Degenerative disc disease is an injury to, or decaying of, the discs that provide flexibility between vertebrae. When the disc breaks down, the result can be restricted spinal movement and severe pain.
Traditional treatment includes spinal fusion, which is the permanent attachment of the affected vertebrae to each other. The immobilization of the portion of the spine prevents further pain but young and active patients may not be able to continue their lifestyles as a result of the procedure. Artificial disc replacement does not affect mobility like fusion does.
This phase of the study is expected to be completed and ready for FDA review in December 2003.
