      Minimally Invasive Surgery with Neuroscience Group

      As technology develops, so does our ability to provide patients with more options for surgical procedures. Minimally invasive surgery (MIS) is an emerging, advanced medical procedure.Minimally invasive spine surgery is a type of surgical technique that is used to treat spine conditions such as arthritis in the back, disc herniation and lumbar stenosis (nerves that are “pinched”). This procedure uses microscopes, magnified glasses called loupes and long tubes that are passed through tiny incisions to access the spine.

      This type of surgery allows the surgeon to remove broken or displaced discs and create more space for crowded nerves, all without having to cut through muscles and bones to operate. MIS also enables doctors to do spinal fusions and disc replacements. Many patients are surprised that they’re up walking the day of surgery and that they can go home within 23 hours. Minimally invasive surgery allows the surgeon to do everything an open procedure does, but in a much less invasive manner.
