What is Spinal Disc Replacement?
Patients who don’t want the immobilization spinal fusion surgery brings may opt to have spinal disc replacement surgery instead. The problem with immobilizing the spine is that the nerves and tissues in and around the spinal cord can become damaged over time. Instead of fusing bones together to eliminate movement between two vertebrae, the degenerating spinal disc is replaced with a prosthetic. The prosthetic discs used in this procedure are often made out of metal, plastic, or ceramic, with hydrogel inside them.
This type of surgical implantation procedure is a great alternative to the more permanent fusion surgeries, but it is still a major surgical procedure. Doctors often recommend surgery as a last resort if medication and physical therapy fail to relieve the symptoms of degenerative disc disease.
Ideal Candidates for Spinal Disc Replacement
While most patients prefer this procedure over stabilizing the spine to treat the symptoms of degenerative disc disease, , not everyone is a good candidate for the procedure. The first thing a surgeon looks at before even considering this procedure as a treatment option, is the patient’s medical history. Patients who have their vertebral discs replaced with prosthetics should have enough bone strength to support the implants, or else the surgery will do more harm than good.
The next thing surgeons do is check to see if traditional non-surgical treatment methods have failed to bring relief. Unless the pain and the symptoms are getting progressively worse over a short period of time, most surgeons recommend holding off on surgery, and may instead recommend treating the symptoms with medication and special exercises first.
How the Procedure is Done
Spinal disc replacement usually takes several hours to complete, but this depends on the number of discs that need to be replaced and how badly damaged they are. The surgical techniques used in this type of procedure vary depending on the location of the affected discs – the approach and techniques for replacing discs in the cervical spine (neck area) is different from that of the thoracic spine (middle area) and lumbar spine (lower back area).
Patients are usually positioned facing up, and the incisions are done in the front for easier access to the discs. The muscles, tissues, and internal organs are retracted to clear the way to the spine, and to avoid damaging them during surgery. X-ray images and fluoroscopy are used to pinpoint the discs that need to be replaced. Once the surgeon spots the problematic discs, they are slowly and gently removed from the space in between the two vertebrae. After that, the gap where the disc used to be is cleaned out, and the prosthetic discs are put in their place.
When the surgeon finishes replacing all the deteriorating discs, they then remove the retractors and close up the incisions made. Extra care is needed when performing this procedure on the cervical spine, as the surgeon needs to move past muscles, arteries, veins, and organs in order to get to the spine.
