Computer Guided Techniques in Spine Surgery - Cervical Disc Replacement Surgery in India

Cervical discectomy is surgery to remove one or more discs from the neck. The disc is the pad that separates the neck vertebrae; ectomy means to take out. Usually a discectomy is combined with a fusion of the two vertebrae that are separated by the disc. In some cases, this procedure is done without a fusion. A cervical discectomy without a fusion may be suggested for younger patients between 20 and 45 years old who have symptoms due to a herniated disc.

Different Approaches to treat Cervical Discectomy Spine Problem :-

• Anterior Approach: The patient is made to lie down on his back under general anesthesia. A horizontal incision is made just 2 inches above the clavicle on either left or right side. The thin muscle layer is cut and the trachea and esophagus are shifted to one side along with the nerves and vessels. 
  The surgeon has a clear view of the cervical vertebrae. An X-ray is done to confirm the involved disc. An operating microscope can also be used to get a better picture of the operating field. The anterior longitudinal ligament is gently removed to reach the osteophytes and the disc fragments. The osteophytes are scraped off and the intervertebral disc is dissected.Once the disc is removed the vertebral bodies are gently distracted to their original distance to fill the space with bone graft. This helps to relieve the compression from the nerves as the diameter of the intervertebral foramen is enlarged. Sometimes cervical discectomy is followed by spinal stabilization using screws and plates

• Posterior Approach: The patient is sedated under general anaesthesia and made to lie on his abdomen. The neck is slightly bent and head is supported on the head rest. An incision is made on the back of the neck in the midline. The skin, fascia and muscles are retraced to reach the vertebrae. An X-ray is done to confirm the level of affected disc.
  
  Edges of the lamina are shaved off to give a clearer vision. Incase of central herniation, both lamina may have to be removed in order to get full view of the fragmented disc. The posterior longitudinal ligament is incised and a small hole is made in the ligamentum flavum. The surgeon now uses a surgical microscope to magnify the operating area and the disc fragments and bony spurs are carefully removed. The muscles fascia and skin are stitched

Minimally invasive cervical disc replacement surgery entails inserting an artificial cervical disc between two cervical vertebrae after the inter- vertebral disc has been surgically removed in the process of decompressing the spinal cord or a nerve root. The intent of the device is to preserve motion at the disc space. It is an alternative to the use of bone grafts, plates and screws in pursuit of a fusion following procedures such a disc removal, which necessarily eliminates motion at the operated disc space in the neck.

Cervical disc replacement surgery is most typically done for patients with cervical disc herniations that have not responded to non-surgical treatment options and are significantly affecting the individuals' quality of life and ability to function.

The advantages of Minimally invasive cervical disc replacement surgery :

• Maintaining normal neck motion
• Reducing degeneration of adjacent segments of the cervical spine
• Eliminating the need for a bone graft
• Early postoperative neck motion
• Faster return to normal activity
• Postoperative neck braces are not required for disc replacement operations.

Our network hospitals have the most advanced spine surgery facilities. The spine surgeons here use minimally invasive and computer guided techniques in spine surgery. In a Minimally Invasive spine surgery the surgeon makes a few small incisions unlike the open surgery where a single large incision is made. Minimally Invasive spine surgery has several important benefits for the patients. If you have been advised spine surgery your first choice should be the latest minimally invasive technique developed by our world best hospitals in India. Most advanced Technology like Intra Operative MRI, Brain Suite and Computer Assisted Navigation System are deployed by highly trained surgeons for accurate and safe Spine Surgeries through a small incision.
