The retractor of the present invention has supporting arms connected at an angle to the retractor blades to remove the arms of the retractor from the top edges of the wound and thus allow for a greater amount of latitude in applying various mechanical devices to the spine. The angled arms on the retractor blades themselves placed these structures deep within the wound and thus apply distraction forces where they are needed the most--near the spine itself to spread the muscles away from the spine and make it easier to see. The blades of this spinal retractor apply distraction forces deep within the wound where they are needed the most. On either side of the angled arms deep within the wound are vertical fingers projecting deeper into the wound on the lower portion and up out of the wound on the upper portion. The distances between the fingers provide further lateral angulation of instruments used in the wound itself for the placement of the spinal fixation devices. This retractor also has a laterally projecting anchor peg extending from the muscle side of the retractor blade which is meant to lie beneath the dorsolumbar fascia.

This invention is a vertebral triplaner alignment facilitator to enable a surgeon to make minute vertebrae adjustments during spinal surgery. The vertebral triplaner alignment facilitator includes a support device which is adapted to support a tensioning device. The support device includes a support structure and a gurney. The gurney is adapted to support the tensioning device, while the support structure supports the gurney above a patient. The support structure typically includes a support rod, a sacral bridge, and adjustment rods. The support rod may be adapted to connect to a retractor. The sacral bridge may be adapted to sit on the iliac spines or crests of the pelvis. The adjustment rods movably engage the support rod and the sacral bridge such that the adjustment rods can move laterally over the patient and longitudinally relative to the retractor. A plurality of gurneys engage the adjustment rods such that they may move along the adjustment rods and may pivot about the adjustment rods. Each gurney tracks and pivots independently of the other gurneys, as does each adjustment rod.
