1. A spinal compression instrument for compressing a first bone structure relative to a second bone structure, the instrument comprising:
a stanchion member having an elongate shaft comprising a stanchion proximal end and a stanchion distal end, the stanchion distal end adapted to engage a tulip portion of a first bone anchor;
a sleeve member at least partially encircling the stanchion member; and
a compression lever pivotably connected to the sleeve member at a pivot point to allow the compression lever to rotate relative to the stanchion member about an axis that contains the pivot point, the compression lever comprising a lever distal end and a lever proximal end, the lever distal end adapted to engage a tulip portion of a second bone anchor, the lever distal end further comprising an opening dimensioned to admit a spinal rod at least partially therein,
wherein the opening is adapted to allow a spinal rod passing through the tulip portions of the first and second bone anchors to pass unencumbered through the opening in a direction that is lengthwise with respect to the spinal rod passing through the tulip portions, and
wherein the pivot point is positioned between the lever proximal end and the lever distal end.
