This is a brief technical report about a novel regional anesthesia technique in which local anesthetic was deposited around the thoracolumbar dorsal rami nerves via 4 multiorifice pain catheters to obtain analgesia for posterior spinal fusion surgery on scoliosis patients. Scoliosis is the most common deformity of the spine. Currently, most surgeons prefer a dual rod, segmental spinal fixation system that allows multiple anchor points for attachment to the deformed spine. Scoliosis surgery is an extremely painful surgical procedure due to the large incision, surgical trauma to superficial and deep muscles of the back, and the insertion of pedicle screws and metal rods directly into the vertebral column. Postoperative pain management remains very challenging.
