- category: Acetabular Solutions
With over 10 years experience the PINNACLE® Acetabular Cup System is DePuy’s premium product for acetabular indications and can address all existing pathologies. For the first time surgeons have the choice between high performance bearings which all work within the PINNACLE® Acetabular Cup System. This has been made possible through the improved material characteristics in the ceramic liner and a unique taper technology that is specifically designed to not only give maximum support to hard on hard bearings but also guarantees an optimal thickness of polyethylene liners.
3 in 1 Versatility
With the patented VIP taper the PINNACLE® shell is able to house Polyethylene, Metal and Ceramic liners thus allowing for maximum versatility and Intraoperative flexibility. Unique Coating Technology 25 years of clinical heritage in POROCOAT® porous coating technology provides maximum bone in growth. PINNACLE® 100 and sector shells are also available with an additional Hydroxyapatite coating to further enhance bone on growth.
MARATHON® Cross–Linked Polyethylene Inserts
The PINNACLE® Acetabular Cup System combines optimal cup/ polyethylene insert congruency to help minimise micro motion. With the clinically established wear resistance of MARATHON® Cross–Linked Polyethylene, larger head diameters can be used to improve functional range of motion and reduce the risk of dislocation, while maintaining adequate thickness of the polyethylene insert.
ULTAMET® Metal–on–Metal
The PINNACLE® Acetabular Cup System’s ULTAMET® Metal–on–Metal Insert is manufactured from forged high–carbon wrought alloy. Precision controlled manufacturing of the bearing surfaces results in specially engineered articular surface clearances. Sophisticated manufacturing and advanced grinding and polishing techniques enable ULTAMET® Metal–on–Metal Inserts to achieve a very low surface roughness. All of these factors help contribute to exceptionally low wear rates.
CERAMAX® Ceramic–on–Ceramic
The ceramic material offered with the PINNACLE® Acetabular Cup System is CERAMAX® Ceramic, Biolox® delta a composite material with a unique combination of toughness and structural integrity. Through an exhaustive process of assessment and testing, CEREMAX® Ceramic has been developed to incorporate the best characteristics of ceramics as implant materials. The outcome is a material with the wear behaviour and excellent biocompatibility, but improved mechanical properties when compared to alumina, and the state-of-the-art performance of Ceramic–on–Ceramic joints.
PINNACLE® Ceramic–on–Metal
The ceramic-on-metal bearing combination brings a new option for the surgeon within the DePuy high performance bearing range. The use of differential hardness bearings has been common in many different industries, as a solution for optimised wear performance. DePuy has embraced this technology by extensively testing the combination of their CERMAX® ceramic head and their ULTAMET® metal liner. The results show improved wear performance and reduced metal ion release. Design flexibility allows for Ceramic–on–Metal bearings up to a head diameter of 44 mm for enhanced stability and to prevent dislocation. Ceramic-on-Metal bearings combine the extremely low wear of ceramic and toughness of metal, for active and demanding patients.
