Best-in-class just got better

Building on the clinical success of our POLARSTEM◊ Hip System,2 the CATALYSTEM System is designed to address the changing demands of primary hip surgery (including the growth of ambulatory surgery centers (ASCs) and increased adoption of anterior approaches); introducing distinct implant innovation.

  • Precise: Designed to address the global patient population,3 the CATALYSTEM System provides uniform proximal loading*4 and a reduced distal stem geometry, minimizing the risk of undersizing, distal potting and calcar fractures5-7
  • Confident: Achieve proven broach to implant reproducibility using proprietary ACCUBROACH Technology, giving you the confidence of predictable stem seating1
  • Efficient: A single modular tray, tailored to your approach, can provide efficiencies in facilitating more shelf space and reduced sterilization costs8

 

Advanced bearing science

The only cementless stem of its kind to feature OXINIUM◊ Technology bearing material, offering the durability of metal, the wear resistance of ceramic and corrosion resistance better than both.9-13 Demonstrating performance over 20 years of clinical use, OXINIUM Technology has been shown to minimize taper corrosion in total joint arthroplasty.14,15
The combination of unique OXINIUM Oxidized Zirconium heads with a highly cross-linked polyethylene (XLPE) liner has been shown to result in the lowest revision rate of all modern bearing combinations in four national joint registries.**16-19
