Does the CONSERVE® PLUS acetabular shell with the big femoral head use the same clearance for all sizes?
No. The clearance between components is size-dependent. The larger the diameter, the larger the gap between the components. The range for the entire family of sizes is from 90 to 200 microns of diametral clearance, each bearing size having an optimized gap for maximum fluid film thickness. 5.) I’ve heard a lot about heat-treated cobalt chrome components versus “as cast” components. What are they talking about and is there a difference? Cobalt Chrome Molybdenum components that are cast usually go through the hot isostatic pressing (HIP) and solution annealing processes to remove microporosities often found in castings and to improve the ductility and homogeneity of the material. The microstructure of this type of heat-treated material looks different from that of the original casting. It is important to note that even though heat-treated material looks different, it doesn’t affect wear. Two global metal-on-metal resurfacing manufacturers use the heat-treated process for the castings (Co
