Abstract: A captive locating screw system comprising a captive locating screw assembly configured for use with a bushing assembly. The captive locating screw assembly has a gripping means attachable to be threaded shaft or stud and an optional protecting means disposed between the gripping means and the body of the shaft. The protecting means may be a washer or other similar structure, and remains statically in contact with a workpiece or work surface, to reduce damage or marring, even as the captive locating screw assembly is rotated by twisting the gripping means to fasten it to the workpiece or work surface.

Abstract: A method of manufacturing a distal femoral knee prosthesis includes the initial step of forming a rough prosthesis workpiece member that has the approximate size and shape of a final polished distal femoral prosthesis. The rough prosthesis workpiece member can be a casting, forging or a rough machined part. The prosthesis member is then attached to a fixator and movably supported adjacent a grinding wheel in a numerically controlled grinder. Relative motion between the grinding wheel and the prosthesis is controlled with a computer. An articular surface of the prosthesis is shaped by engaging the prosthesis with the rotary grinder. The grind program for the numerically controlled grinder is generated from data representing a CAD/CAM model of a joint prosthesis. The process of generating the grind program includes first the step of generating path data points for a ball-endmill having a radius equal to the nose radius of the rotary grinding wheel.
