The purpose of installing the artificial intervertebral disc is to eliminate pain and improve mobility in patients with chronic back pain. Currently, this surgery is a modern alternative to spinal fusion - fusion of two vertebrae. When spinal fusion there is a risk of degenerative changes in the vertebrae.
Intervertebral discs are located between the vertebrae and act as shock absorbers. In addition, the intervertebral discs of the spine movements promote its flexion, extension.
In the aging process erases intervertebral discs, they may form defects, degenerative changes. Through these defects can extend in a herniation of the nucleus pulposus, which is located in the center of the disc. The aim of the replacement of the intervertebral disc with an artificial one is to restore the movement between the vertebrae.
American organization FDA, which is responsible for approving new drugs recently approved the use of artificial intervertebral discs. There is currently no long-term results of this type of treatment of disc herniation.
Preparation for surgery
Preparation for surgery to replace the intervertebral discs is the same as with other operations in spinal surgery. It spent the whole spectrum of research, which are necessary before surgery (blood, urine, x-ray and other imaging techniques). Before the surgery, the patient visits the anesthesiologist. It turns out the presence of allergy to drugs.
The operation is performed transabdominal, that is, access to the spine through the abdomen is obtained. After incision abdominal contents is moved sideways and becomes visible spine. Struck by the intervertebral disc is removed. In its place installed two metal plates. Between them installed plastic backup to the vertebrae can move between them.
After operation
Most of the patients after surgery can have a little walk in the evening. After two or three days, the patient may be discharged. During the first month after surgery should limit physical activity. The recovery period after such operation takes about six to seven months.
