ABSTRACT:
A technique for producing a highly convoluted surface on a prosthetic device is achieved by applying a layer of aspherical metallic powder on the surface of the device. The metallic powder, which may be the same as or different from the material of the device, is applied in a thickness of up to approximately 200 microns and has a size range of approximately -80 to +635 mesh so as to result in a desirable surface roughness defined by a peak to valley variation of up to approximately 200 microns. A resulting device has an enhanced surface which provides, alternatively, an improved press fit into a receiving bone, or improved cement fixation, or improved reception of a ceramic coating.
