The METRx System surgical procedure is a minimally invasive operation on the lumbar (low back) or cervical (neck) spine and requires only a very small incision. It allows the surgeon to remove only the portion of your ruptured disc, which is “pinching” the spinal nerve root. The patient is under anesthesia and a small incision is made over the disc space. The muscle is then dilated to avoid any unnecessary muscle damage. The ruptured disc is removed through the small tube and the wound is closed with sutures followed by a small bandage.
