Medtronic PRESTIGE® Cervical Disc Artifical Disc Replacement

Artifical Disc - The PRESTIGE® Cervical Disc

The PRESTIGE® Cervical Disc is an artificial disc replacement which is designed to maintain motion for patients suffering from the symptoms of degenerative cervical disc disease or acute unresolved cervical disc herniation.

The PRESTIGE® Cervical Disc offers patients with radiculopathy and myelopathy related to degenerative cervical disc disease (DDD) in the cervical spine an alternative to spinal fusion surgery. Constructed of stainless steel in a unique, two-piece ball-and-trough configuration, the device is designed to maintain motion at the treated vertebral segment.

Each vertebra in the spine is separated by a shock absorbing disc, which is made up largely of water. As discs lose water content because of disease, injury or age, they compress, or lose height, which causes the vertebrae to move closer together. This reduces the disc's shock absorbing qualities, which may lead to bone spurs and narrowing of the nerve openings. If a disc ruptures, it can place pressure on the surrounding nerve roots and the spinal cord, resulting in pain, numbness and/or weakness.

Your doctor may recommend surgery if non-surgical treatment fails to provide relief from these symptoms. Traditionally, a procedure called an anterior cervical discectomy with fusion (ACDF) has been the "gold standard" for surgically treating DDD in the cervical spine. Using bone grafts and instrumentation such as metal plates and screws, this procedure fuses, or creates a bond between, two or more adjacent vertebrae, ideally stabilizing the segment and providing relief. Many patients have achieved excellent results with ACDF; however, a potential disadvantage associated with spinal fusion is the loss of motion and flexibility in the treated vertebral segment.

The PRESTIGE® Cervical Disc replaces a diseased or damaged disc and is designed to maintain motion. Made of stainless steel, the device has two articulating components (a ball on top and a trough on the bottom) that are inserted into the disc space and attached to the vertebral bodies on either side. The PRESTIGE® Cervical Disc was designed to allow for the following motions of a natural intervertebral disc: flexion, extension, side bending and rotation.

The PRESTIGE® Cervical Disc is available in a variety of sizes that allow your surgeon to closely match a patient's anatomy.

The PRESTIGE® Cervical Disc may be an appropriate surgical treatment option for patients with radiculopathy and/or myelopathy related to degenerative disc disease in the neck, or cervical spine.
Prestige Cervical Disc - Artificial disc replacement

Neck pain? Arm pain? Weakness? Numbness? The PRESTIGE® Cervical Disc is generally indicated for use in the C3-C7 levels of the cervical spine to treat symptoms such as arm pain or weakness caused by degenerative disc disease in the neck. Print out a handout to take to your doctor.

The PRESTIGE® Cervical Disc is not indicated for patients with any of the following conditions:

• Infection
  
• Local inflammation
  
• Segmental instability
  
• Morbid obesity
  
• Pregnancy
  
• Mental illness or incompetency
  
• Suspected or documented metal allergy or intolerance
  
• Rapid joint disease, bone absorption, osteopenia or osteoporosis
  
• A known hereditary or acquired bone friability or calcification problem
  
• Remaining general skeletal growth (pediatric)
  
• Severe osteomalacia, or metabolic bone disease
  
• Disease or surgical problem that would preclude the potential benefit of spinal implant surgery, such as tumors or congenital abnormalities, local operating site fracture, elevated sedimentation rate, or marked left shift in the WBC differential count
  
• Inadequate tissue coverage over the operative site
  
• Any condition not described in the indications
  
• Unwillingness to cooperate with postoperative instructions

It is important that you discuss the potential risks, complications, and benefits of the PRESTIGE® Cervical Disc with your doctor prior to receiving treatment, and that you rely on your physicians judgment. Only your doctor can determine whether you are a suitable candidate for this treatment.
