Abstract: A system and method for performing percutaneous spinal stabilization, comprising inserting a k-wire into skin and tissue proximal to the spine; drilling the k-wire into and through the spinous process, creating a narrow aperture therethrough; inserting one or more cannulas over the k-wire, through the skin and tissue and towards said bone, a second cannula configured to fit over the first; removing all but the outermost cannula, thereby creating a working channel through the skin and tissue, providing unobstructed access to the bone; inserting into the channel a screwdriver comprising a preferably flexible shaft long enough to extend through the cannula to the bone, and having releasably attached to the end a screw with external screw threads; and drilling one or more screws into and through the bone for securement to a cap secured to a hollow, oval, flat stabilizing plate positioned on the opposite side of the bone.
