Abstract
In one form, a method for stabilization of a facet joint of the spinal column includes forming a cavity between adjacent bones defining the facet joint and positioning an implant in the cavity between the adjacent bones. In one aspect of this form, the method also includes positioning a bone anchor across the facet joint and engaging the bone anchor with each of the adjacent bones to force the bones toward one another and clamp the implant therebetween. In a further aspect of this form, the implant is a cancellous bone dowel and becomes fractured into a plurality of fragments upon being clamped between the adjacent bones and/or otherwise interacting with the bone anchor. In another form, systems and devices for performing percutaneous facet joint stabilization and/or fusion are provided. However, different forms and applications are also envisioned.
