LinkedIn, visit:   / drdonaldcorenmanspinesurgeon   Dr. Donald Corenman is one of a handful of back doctors that are both a MD and doctor of chiropractic (DC). His practice with the Steadman Clinic in Vail, CO serves the Vail and Denver area with patients traveling from the US and abroad seeking resolution for chronic back pain and failed surgical treatment. Dr. Donald Corenman, MD, DC (http://neckandback.com), is an orthopedic spine surgeon with the Steadman Clinic in Vail, CO and is a passionate researcher and lecturer on all topics associated with the cervical, thoracic and lumbar spine. Dr. Corenman is a dedicated Vail spine surgeon and recently launched a spine resource site on the Internet for patients, physicians and other spine surgeons seeking additional information. You can visit his website at http://neckandback.com to learn more about his expertise and about all spinal conditions and surgeries. An artificial disc in the lumbar spine was created and has been designed to allow some motion of the defective segment by replacing the damaged disc with this implant. This spinal disc implant surgery theoretically reduces some stress on the segment above to prevent further degeneration of this superior segment. The artificial disc in the lumbar spine, however, has some significant deficiencies that need to be discussed. First-the artificial disc does not mimic the behavior of a normal lumbar disc. The normal lumbar disc allows motion but is restrained at the endpoint of motion. That is-the normal disc acts like a bushing where motion at the extreme limits is dampened by the fibers of the annulus. The artificial disc does not have this constraint and this puts more stress on the facets than the normal disc would. Also, the artificial disc does not have shock absorption capabilities like the normal disc does. This rigidity in compression can allow increased wear and can cause back pain after implantation. Second-spinal disc implant surgery to implant the disc is done from the front of the spine through the belly. The vena cava, aorta and great vessels need to be mobilized to implant this disc. This in itself can be a problem. The greater problem is if this disc needs to be replaced in the future. The adhesions that form from the initial spinal cord implant surgery can make removing or replacing this disc dangerous. In addition, injury to the sympathetic nerve plexus that lives next to this disc can occur. At the minimum, this would cause a "warm leg sensation" on one side and in males, there is a 3-5% chance of retrograde ejaculation. Abdominal hernias can occur as the belly wall needs to be incised to implant this disc. The third area to note with artificial discs in the lumbar spine is that over time, if the patient becomes osteoporotic, the disc can erode into the endplate of the vertebra, which causes increased pain, and dysfunction of this segment. Fourth is that the disc is made of chrome-cobalt alloy. This alloy obscures MRI images so assessment of this segment in the future becomes much more difficult. Finally the lack of "normal" motion of the artificial disc can wear out the facets in back which will lead to back pain and fusion of the segment. Also, this motion can allow bone spurs to occur which could lead to nerve root compression. Artificial discs in the lumbar spine inserted through spinal disc implant surgery should be carefully thought out before the procedure takes place. This surgery has proven to be very successful for many patients. Dr. Corenman, MD, DC, is Vail spine surgeon in Colorado and sees and treats patients from all over the world at his Vail, CO office.
