Proven Coating Fixation Technologies
Initial and long-term component fixation are key to restore joint function. With the PINNACLE® Cup, fixation is achieved through 180° of either POROCOAT®, DUOFIX® with Hydroxyapatite (HA) or GRIPTION® Coatings.
The proven cementless coating fixation technologies1-3 are based on the outstanding clinical performance4-6 of POROCOAT Porous Coating, which was introduced with the AML™ Cup in 1977, with the DURALOC® cup 1980 and with the PINNACLE cup in 2000. Therefore it has been clinically tracked for over 30 years.4-6 The DUOFIX Fixation System was introduced with PINNACLE cups in 2003 being an evolutionary combination of POROCOAT Porous Coating and highly amorphous hydroxyapatite (HA). Finally, in 2009 the GRIPTION cup fixation technology emulated the reliable foundation of the POROCOAT Porous Coating being also an evolutionary development in implant fixation technology due to an advanced 3D structure.5-10
