Alternative Bearing Solutions

Longevity® Crosslinked Polyethylene Liners
Longevity Crosslinked Polyethylene was developed to address the issue of wear in total hip arthroplasty. To help ensure optimal wear resistance, Zimmer employs a proprietary process based in part on patents licensed from Massachusetts General Hospital and Massachusetts Institute of Technology.
Removable Longevity Liners are available in standard, 10-degree and 20-degree elevations, and 7mm offset. This offers a range of options to assist the surgeon in optimizing femoral head coverage and restoring proper hip kinematics. Read more > 


Limit Wear, Not Options
Patient longevity and active lifestyle have led to an increase in the physical demands placed upon THA bearing surfaces. As a result, implant manufacturers are continuing to search for ways to improve performance of these bearing surfaces and have introduced several products to help address the issue.
As with any bearing surface, the primary concern for orthopaedic surgeons is wear and the impact that wear debris has on THA. Although the vast majority of total hip arthroplasties are successful, in the small amount that do fail, literature reports osteolysis as a primary limiter of implant service life. Read more >


Durasul® Highly Crosslinked Polyethylene
A breakthrough in long-lasting joint replacement.
A leading problem in hip and knee replacement is the wearing down of the implant surface over time. Continuous motion between the metal and plastic polyethylene components can cause small particles to be removed from the surface of the polyethylene. Also, the polyethylene may degrade, or age, over time. Durasul polyethylene was developed to address the problems of wear and aging. Read more > 


Metasul®
The Strength of Metal-on-Metal
Developed and refined in Europe for over 40 years, Metasul has helped over 140,000 patients worldwide. In 1988, after rigorous testing at 15 independent clinical sites in the United States, Metasul was cleared for use in the United States. In the Metasul implant, the conventional plastic polyethylene insert has a cobalt chrome metal inlay. This helps minimize wear over time, potentially increasing the longevity of the implant. Read more >  


Metasul® LDH® Large Diameter Head
The Metasul bearing has been the target of continuous research and development, with clinical results since 1988. This technology is not only the basis for the modular large diameter heads – Metasul LDH components – but is also an industrial benchmark for combinations with low metal-on-metal wear.  The head size range includes 12 diameters from 38 to 60mm with neck length adaptors of -4, 0, +4, and +8mm.  Read more > 


BIOLOX® delta Ceramic Material   
The BIOLOX delta Ceramic femoral heads are made from a new alumina matrix composite developed by CeramTec AG. This material is a high-performance ceramic that meets the increased demands regarding durability of the implants in young, active and heavy patients. Read more >


BIOLOX® OPTION Head System   
Features and Benefits
The BIOLOX OPTION head system consists of two components:

  • Metal adapter sleeve Titanium alloy TiAl6V4 (ISO 5832-3), inner taper 12/14 or 8/10 that interlocks with the femoral stem.  
  • Biolox delta Ceramic head High-performance composite ceramic BIOLOX delta with a special inner taper. Read more >
