A minimally invasive spinal fusion back surgery results in less blood loss, less postoperative pain, smaller incisions, a shorter hospital stay and faster recovery and return to work. Rather than cutting through paraspinal (back) muscles, the surgeon spreads and dilates the muscles to obtain access to the lumbar (lower back) spine.
