FDA Approves First Artificial Disc For Treatment Of Low Back Pain
New Motion Preserving Device Offers Alternative to Spinal Fusion Surgery
Raynham, MA – (October 26th) - The U.S. Food and Drug
Administration (FDA) has approved the CHARITÉ™ Artificial
Disc, a device that treats severe low back pain by replacing a damaged
or worn out spinal disc with an artificial one. The approval was announced
today by DePuy Spine, Inc., a Johnson & Johnson company, the manufacturer
of the disc.
While artificial replacements are commonly used in hips and knees, this
is the first FDA approval of such a device for spinal discs.
“The CHARITə Artificial Disc has the potential to revolutionize
spine surgery,” said Scott Blumenthal, MD, principal investigator
in the CHARITə Artificial Disc clinical trial and an orthopaedic spine
surgeon from the Texas Back Institute in Plano. “Until now, spine
surgery relieved pain by limiting motion. Now, for the first time, we
can relieve pain and preserve motion.”
The CHARITə Artificial Disc is a high-tech device made of two metallic
endplates and a movable high-density plastic center that, once implanted,
is designed to help align the spine and preserve its ability to move.
Spinal discs maintain the position of the spine and allow for the flexibility
to bend and twist.
Lumbar spinal fusion surgery, a common surgical treatment for low back
pain or degenerative disc disease, is often effective in reducing pain,
but limits range of motion and may transfer extra stress to discs above
and below the fusion site. More than 200,000 of these procedures are performed
each year in the U.S.
In clinical trials comparing artificial disc replacement to spinal fusion
surgery, CHARITə Artificial Disc patients maintained flexibility, experienced
improvements in pain and function, left the hospital sooner and were more
satisfied with the procedure. Complication rates for both groups of patients
were similar.
CHARITə Artificial Disc Patients Return to Work Sooner
According to John Regan, MD, a spine surgeon at Cedars Sinai in Los Angeles
and a clinical investigator, CHARITə Artificial Disc patients were able
to return to work and normal activity sooner than his spinal fusion patients.
“At our center, CHARITə Artificial Disc patients returned to work
in 12 weeks or less, which was far better than the spinal fusion patients
who were not able to go back to work for about six months,” said
Dr. Regan.
How the CHARITə Artificial Disc Procedure is Performed
Typically, two surgeons work together in performing the operation. A general
or vascular surgeon approaches the spine through an incision in the abdomen
and carefully moves internal organs and blood vessels out of the way to
provide access to the spine. A spine surgeon then uses special tools to
remove the damaged disc and creates a space between two vertebrae for
the implantation of the artificial disc. The procedure generally takes
one to two hours.
In spinal fusion surgery a damaged spinal disc is removed and vertebrae
are joined together using bone grafts and metal screws and/or cages so
that motion can no longer occur in this area of the spine. Patients usually
have to wear a brace for about three months after surgery.
Not for Everyone, Talk to Your Doctor
Artificial disc replacement is not for everyone. As with any major surgery,
there are possible complications that can occur including unresolved pain,
allergic reactions, bladder problems and/or infection. Patients should
ask their doctors to see if artificial disc replacement is appropriate
for them.
More information about the CHARITə Artificial Disc is available at www.charitedisc.com
or by calling 1-866-DISC523. These resources also provide information
that will help consumers find a doctor in their area who has been trained
in artificial disc replacement.
Currently, there are 15 spine centers throughout the U.S. who offer disc
replacement with the CHARITə Artificial Disc. Many more centers are expected
within the next several months as surgeons receive extensive training
in the procedure. Patients may have to wait several weeks or months while
surgeons complete this mandatory training.
Surgeon Training is Top Priority
DePuy Spine is sponsoring a comprehensive training and education program
for surgeons. The program is a combination of hands-on surgery, consultation
and visitation with top spine surgeons, lectures and web-based educational
materials. Much of the training will take place at The Center for Spine
Arthroplasty at the Endo-Surgery Institute. More than 50 regional training
centers throughout the country will also provide training.
“Training is critical to the appropriate and effective use of the
CHARITə Artificial Disc and it will be our top priority,” said
Earl R. Fender, Worldwide President, DePuy Spine. “Many leading
spine surgeons are involved in the design and conduct of the training
program to ensure surgeons have the required skills for this advanced
surgery.”
Back Pain One of the Most Common Problems
About 65 million Americans suffer from low back pain every year, according
to the American Association of Neurological Surgeons (AANS). Americans
spend about $50 billion each year on low back pain, the most common cause
of job-related disability and lost work days.
The CHARITə Artificial Disc is also available in more than 30 countries
throughout Europe, Asia, North America, Africa and Latin America.
