Abstract
An instrument for preparation of vertebral endplates and a method of preparing a surface of a vertebral endplate are described. The instrument includes a body having a frame, an endplate preparation member supported by the body, and a pivot point. A tilt axis is perpendicular to and intersects a sweep axis at the pivot point. The endplate preparation member is coupled to the frame and controllably pivotable in an arc about the first tilt axis to change a tilt of the endplate preparation member. The endplate preparation member is also controllably pivotable in an arc about the sweep axis while maintaining the tilt of the endplate preparation member. By sweeping the endplate preparation member at incrementally larger tilt angles, recesses in a vertebral endplate surface are gradually formed, which may allow greater precision and control of a depth of the recesses and reduce stress on the vertebral endplate, as opposed to more aggressive techniques.
