<p>An apparatus for retaining a bone site in a fixed position and guiding a high-speed power tool (400) for machining the bone, such as a patella, including a positioner frame (20) for rigid attachment about the bone site. The frame (20) includes a bone clamping mechanism (101) capable of adjustment and orientation of the bone site relative to the frame. A hinged power tool mount (250) attaches to the frame (20) and is adapted to receive a power tool (400) for machining the bone in a predetermined manner. A template (200) corresponding to the predetermined manner attaches to the positioner frame (20). The bone clamping mechanism (101) includes a plurality of gripping assemblies (100) adapted to grip the bone about multiple locations.</p> |
