X-alt™ and Biolox® delta

The Perfect balance between strength and wear.

Less wear is our strength.

Where is our strength?

Optimizing crosslinking parameters provide X-alt highly crosslinked polyethylene with maximum wear properties while maintaining maximum strength characteristics.  Biolox delta ceramic heads provide an increase in strength over traditional ceramics with approximately half the wear of a comparably sized Cobalt Chrome head.  In combination, X-alt highly crosslinked polyethylene and delta ceramics provide the perfect synergy of maximum strength and minimum wear.

X-alt™ crosslinking parameters provide an optimized balance between wear reduction and material strength. Lower wear means less chance for particle-induced osteolysis and subsequent implant loosening.

Melt-annealed for consistent material properties over time.  If not removed, free radicals can bond with oxygen, causing the material to degrade. The annealing step removes free radicals, providing stability against oxidation.

Larger diameter heads increase range of motion and head “jump distance”, enhancing joint stability and helping to avoid dislocation.
 

X-alt is crosslinked to address the number one cause of THA failure. Wear-induced osteolysis is caused by the body’s inflammatory reaction to polyethylene wear debris. Subsequent implant loosening is the number one cause of total hip failure. Highly crosslinked polyethylene shows dramatically reduced wear in hip simulator tests, and these results have been validated clinically.
