This Minimally Invasive Spinal procedure is performed with a posterior approach (from the back). First, the surgeon will make a small incision over the affected vertebra and begin gently moving muscle aside. Specialized instruments are then used to remove the lamina, to create the extra room in the spinal canal for the nerve roots. If a herniated disc is present, the surgeon may also remove that portion of the disc, along with any bone or soft tissue that may be the cause of pressure or pain.
