Abstract
A device and method for contouring articular processes of a facet joint includes a guide with a spacer extending outward in a longitudinal direction from a distal end of the guide. The spacer includes a width to space apart the articular processes in a widthwise direction. A cutting member that is offset the spacer in the widthwise direction includes a cutting edge oriented to contour one of the articular processes in the longitudinal direction. The cutting member may be fixed or moveable relative to the guide. If the cutting member is moveable relative to the guide, the guide may include a guide edge along which the cutting member moves to control the accuracy of the contouring. A second cutting member may be offset a second side of the spacer in the widthwise direction and include a second cutting edge oriented to contour the second articular process in the longitudinal direction.
