Percutaneous arthrodesis method and system

A percutaneous fusion method to correct disc compression in a patient, comprising:

• making a posterolateral incision to access a desired spinal motion segment;
• determining a target level of a disc space between adjacent vertebral bodies for implantation of a spinal implant;
• locating a path to the disc space at the target level;
• inserting a guide wire to maintain the path to the disc space;
• selecting an appropriately sized graft implant;
• placing a spinal implant over the guide wire;
• sliding the spinal implant along the guide wire to position the spinal implant into the disc space at a desired position;
• removing the guide wire;
• and
• fixating at least a portion of the desired spinal motion segment.
