What is a Lumbar Artificial Disc Replacement (ADR)?
As a lower back surgeon, Dr. Braxton performs artificial disc replacement (ADR) for patients suffering from lumbar spine degenerative disease. The goal of this surgical procedure is to improve the function of the lumbar spine with increased range of motion and load capacity to the lower back. Dr. Braxton works closely with patients to determine if artificial disc replacement is the recommended course of treatment.
There are a number of surgical artificial disc replacement techniques that Dr. Braxton may recommend. The right treatment plan will be recommended depending on a patient’s condition. Two common options of lumbar artificial disc replacement include a lumbar disc nucleus artificial replacement and a total lumbar disc artificial replacement. A lumbar disc nucleus artificial replacement involves removing the diseased disc nucleus and inserting the artificial disc nucleus in the disc space between adjacent vertebrae. In this case, the outer band disc (the annulus) is not removed. A total artificial disc replacement involves the removal of all or the majority of the disc material.
Both the artificial disc nucleus and the total artificial disc devices are made of materials that have a high success rate for patient outcomes. The total artificial disc device has a top and bottom metal plate designed to attach with adjacent levels of the lumbar spine. The artificial nucleus device design replicates the normal disc with a soft, compressible interior and a smooth, curved outer surface. The artificial disc nucleus has organic hydration capabilities of a healthy disc which helps facilitate the overall function of the disc. Dr. Braxton’s patient evaluation will determine which lumbar artificial disc replacement is the best choice for optimal outcome.
