A spinal clip for creating a potential space within the spinal canal and thus stabilizing the spine without the need for additional spinal components is embodied in different forms. The spinal clips are configured to provide a clamping or holding force against and / or to the spinous processes, transverse processes and / or the lamina of adjacent vertebrae. In one form, the spinous process clips utilize pivoting to effect clamping or holding. In another form, the spinous process clips utilize rotation to effect clamping or holding. Such rotation may be between clamping or holding members or via a screw system. In yet another form, the spinous process clips utilize ratcheting to effect clamping or holding. In a still further form, the spinous process clips utilize expansion to effect clamping or holding. Depending on the form of clamping or holding, the spinous process clips can provide infinite adjustment of the clamping or holding force within an adjustment range, or provide discrete steps or levels of the clamping or holding force.
