The primary difference lies in the backing of the acetabular component. The BHR (Midland Medical Technology) uses a cast porous surface with a hydroaxiphate (HA) coating to promote bone ingrowth. The Wright Conserve Plus using a sintering process to affix cobalt chrome beads to the back surface. The Corin Cormet device has a plasma sprayed titanium backing with an HA coating. MidMedtech asserts that the heating of the device in the sintering or plasma spray process weakens the metal integrity. It has been shown in laboratory tests however, that when the machining tolerances are identical, the wear rate is not affected by the heat treatment. (more…)
