The spinal compression system includes systems and instruments that allow vigorous compression of two bone structures while minimally impeding visual access to the surgical site. This is achieved by use of a sleeve member that connects a stanchion to a lever. The system includes a stanchion member, a sleeve member dimensioned to at least partially encircle the stanchion member, and a compression lever including. The sleeve and the lever form a pivot point to allow the compression lever to rotate relative to the stanchion member when the sleeve is reversibly placed around the stanchion member.
