Spinous stabilizing system comprises spaced apart, pointed staples held to a connecting rod, a stabilizing plate and a set of locking caps for the staples tips. The tips are forced through the spinous process and captured/secured by the locking caps, pulling the stabilizing plate against the spinous process and toward the heads of the staples and connecting rod. A pair of pliers loaded with the components on the lever arms can be squeezed together to cause the tips of the staple to penetrate the spinous processes and then become frictionally captured within the locking caps. The spacing between the staples are adjusted, pre-installation, by a locking screw acting on the connecting rod or, alternatively, after the device is percutanteously inserted, by laterally directed locking screws which mate with and cam a locking wedge. Matingly engageable speculated plates, installed by pliers, can also be used for spinous fixation.
