A new design for a canine elbow joint replacement was manufactured and assembled. The design incorporates a ceramic ball for articulation with radius and ulna components and a bioactive ceramic for tissue contact. A variety of materials were considered, with zirconia-toughened alumina selected as the wear surface, stainless steel as the structural backbone, and osteoceramic as the bioactive bone interface. The ceramic components were manufactured by cold isostatic pressing the powders, firing the formed rods to an intermediate temperature for strength, and then machining them before a final sintering. A modified osteoceramic bone cement with better flow characteristics was chosen instead of poly(methylmethacrylate) bone cement for fixation of the ulna component.
