Using an anterior or intra-abdominal surgical approach, the present tool is inserted between the adjacent displaced vertebrae such that the foot portion associated with the posterior compression member engages the posterior vertebral margin of one of the adjacent vertebrae and the foot portion associated with the anterior compression member engages the anterior vertebral margin of the other adjacent vertebrae. With the nut member and handle member properly positioned and engaged, rotation of the handle member will cause the nut member to tighten against the anterior compression member thereby causing relative movement between the two respective flange portions and thereby effecting reduction of the vertebral displacement. | |
